Scavenger Hunt: 46-50

50. Endosperm

Endosperm is the tissue produced in the seeds of most flowering plants. It is the tissue containing stored food in a seed that surrounds the embryo and is eventually digested by the embryo as it grows at the time of fertilization.

49. Xylem

Xylem is the wood of a tree, made up of strong fibers, tracheids and vessels. It is vascular tissue designed to help transport water and minerals from the root to the leaves. This is a picture of the bottom of a tree. Xylem helps this tree's leaves recieve enough water.

48. Rhizome

A rhizome is a horizontal underground stem, with leaves and buds, that serves as a storage organ and a means of vegetative propagation. It is a horizontal underground stem of some plants that sends out roots and shoots from its nodes.

47. Biome

This is a picture from Shelter Island. Beyond the water is a forest, which is an example of a biome. A biome is aliving community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region. Biomes include: permanent ice, mountain, desert, grassland, scrub forest, chaparral deciduous forest, taiga, and tundra.

46. Radial Symmetry

This lemon is a picture of radial symmetry. Radial symmetry is a form of symmetry in which the parts of an organism are arranged concentrically around a central oral/aboral axis and more than one imaginary plane through this axis results in halves that are mirror-images of each other.

Scavenger Hunt: 41-45

45. Dominant vs. Recessive

This picture shows a dominant gene vs. a recessive gene. Brown hair is dominant (D) over blonde hair (d).

44. Endotherm

This is a picture I took on a fishing trip this summer. It is a seagull which is also and endotherm. An endotherm is a warm-blooded animal species is one whose members maintain a constant body temperature or thermal homeostasis.

43. Cambium

Cambium is a layer of active cells that separates the xylem and the phloem. These cells produce the new xylem and phloem that are represented by the annual rings of trees. This picture is part of a tree stump.

42. Evidence of different alleles for the same trait

Alleles are either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character. Some alleles are dominant over others. My mom's eye is brown and my sister's eye is blue/gray.

41. Adaptation of a Plant

Plants have adaptations to help them survive (live and grow) in different areas. In this picture, this plant adapted to conditions of growing in between concrete.

Scavenger Hunt: 36-40

40. Auxin Producing Area of a Plant

Auxin is a plant harmone that stimulates growth. Auxin moves only downward but gravity does not cause its movement. It is generally produced by apical shoot meristems and developing leaves.

39. Mating Behaivor

I was being "very careful" when I took this picture of "mating behaivor." Mating is a very essential process for all living organisms on this earth. In order to keep a species alive, mating is necessary. Many animals exhibit different mating behaivors.

38. Pollinator

Although it is hard to see the bee in this picture, it is an example of a pollinator. The bee is an insect that carries pollen from one flower to another.

37. Modified Root of a Plant

This carrot is considered to have a modified root. A modified root is the usual underground portion of a plant that lacks buds, leaves, etc. These include carrots, turnips, and beets.

36. Modified Stem of a Plant

Modified stems located below ground are bulbs, corms, rhizomes, and tubers. This picture is an onion which is considered to be a bulb.

Scavenger Hunt: 31-35

35. Genetic Variations within a Population

In this picture, you can see the same species of flowers. However, the physical colors of them are different. This shows a genetic variation.

34. Difference between Monocots and Dicots

In this picture, the grass is a monocot while the carrot is the dicot. A monocot is any of various flowering plants, such as grasses, orchids, and lilies, having a single cotyledon in the seed. A dicot hsd two cotyledons and the stem grows by deposit on its outside.

33. Gymnosperm Cone

This is a picture of a gymnosperm cone. Their female sex germs reside in ovules, as in regular flowers, but the ovules themselves are not enclosed within the flower's ovaries, as they are among flowering plants.

32. Flower Ovary

A flower ovary is an ovary in a part of the female reproductive organ of the flower or gynoecium. In this picture, I zoomed in so the inside of this flower's reproductive organs are visible.

31. Cuticle Layer of a Plant

This is a cuticle layer of a plant. The cuticle layer is a protective layer covering the outer cell layer (epidermis) of the green, aerial parts of land plants. Cuticles protect plants against various kinds of physical and chemical hazzards.

30. Spore

A spore is a haploid reproductive cell, usually unicellular, capable of developing into an adult without fusion of another cell. In this picture, the middle part of the flower contains the spores used for asexual reproduction.

29. Calvin Cycle

The Calvin cycle (or Calvin-Benson-Bassham cycle) is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms. In this picture, you can see the dark spots or dark reactions of C3 photsynthesis on these leaves.

28. Parasitism

Parasitism is a living arrangement in which an organism lives on or in an organism of a different species and derives nutrients from it. In this picture, a fly feeds off of the microorganisms on this piece of dog feces.

27. Tropism

Tropism is a response to an external stimulus. This plant has the tendency to move towards a specific target (the sun). You can tell that it is growing more towards the left where the sun shines through the window.

26. Lipids for Storing Energy

Lipids are any group of organic compounds including the fats, oils, waxes, sterols, nucleic acids, and triglycerides. Lipids are characterized by being insoluble in water, and account for most of the fat present in the human body. This picture displays a person and one of the "fatty" parts of the body.

Scavenger Hunt: 21-25

25. Animal with a segmented body

This lobster is an example of an animal that contains a segmented body. The segmented body of the lobster consists of a large cephalothorax (made up of 14 segments) and a moveable, muscular abdomen (composed of 7 segments).

24. Different Species in Same Family

This is a growing spider plant which displays different species within the same family. It may be difficult to see, but some leaves contain white lines while others do not. The ones with lines indicate a male while the ones without indicate a female.

23. Predator

A predator is an organism that is hunting which feeds on its prey (the organism that is attacked). In this picture, a spider is making a web to catch insects to feed off of.

22. Population

A population is a group of organisms of the same species inhabiting a given area. There is an ant hill near by this piece of bread which contains groups of the same species of ants. This picture shows a population.

21. Commensalism

Commensalism is the relation between two different kinds of organisms when one receives benefits from the other without damaging it. This is a butterfly bush. Butterflies sometimes feed off this bush and the bush goes unchanged while benefitting the butterflies.

20. Proteins

Meat is one of the many foods that contain protein. Protein is a molecule composed of amino acids linked together in a particular order specified by a gene's DNA sequence. Proteins perform a wide variety of functions in the cell, including serving as enzymes, structural components, or signaling molecules.

19. Redox Reaction

This is rusting iron which displays a redox reaction. A redox reaction is where the atoms in a chemical reaction change their oxidation numbers and there is a loss of electrons resulting in rust.

18. Seed Dispersal

Seed dispersal is the movement or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of ways to disperse its seeds. These include water, wind, and even animals. This pine cone contains seeds in which will eventually disperse to create a new tree.

17. Niche

A niche is the role a particular species plays in its environment and how it can adapt to its surroundings. This is a bird nest located by my pool. Although this is not a usual place for a bird nest to be, it shows how the birds adapted to their environment using the natural surroundings.

16. Long Day Plant

This Iris plant is an example of a long day plant. A long day plant is stimulated by short nights to induce flowering in the spring.

15. Homeostasis

This is John and he is maintaining homeostasis. Homeostasis is the ability of a living organism to maintain an internal equilibrium despite external conditions. His body temperature remains constant while the heat outside is constantly changing.

14. Frond

Frond is the term used to describe the branch and leaf structure of a fern or members of the palm family. This plant is made up of big compound leaves which apply to those of palms.

13. Ethylene

Ethylene is a colorless gas with a sweet ether-like odor that is produced by many fruits and vegetables. It is a hormone that accelerates the ripening of many fruits. This picture is of a very ripe mango.

12. Epethelial Tissue

This picture is an arm which displays epithelial tissue. Epithelial tissue contains cells in animals that are closely packed in either single or multiple layers, and which cover both internal and external surfaces of the animal. It forms an outer layer of body surface such as skin.

11. Autotroph

An autotroph is an organism that is capable of producing complex organic compounds from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions. This is a picture of a dandelion which undergoes the process of photosynthesis to produce its own nutrients.
