50. Spore


A fern is a organism which reproduces through spores. Spores are reproductive part of an organism that is capable of bringing new life directly or indirectly.

49. Predation


 
Predation is the act of an organism preying on another for food. I used a pciture of spiderweb because spiders prey on flies as their source of energy.

48. Gibberellins

Gibberellins is a plant hormone in which regulates growth.

47. Pollinator

 
Being a target for pollinators, we have these flowers in which need pollonators in order to reproduce. Pollinators can go plant to plant transmitting pollen from anthers to stigmas in flowers to fertilize their egg. Bees and hummigbirds are examples of pollinators.

46. ATP


Hidden within the plant's cells, you are able to find the home of production of ATP at a microscopic level in the chlorophlat's mitochondira. ATP's purpose is to store engery for the plant.

45. Krebs Cycle


All organisms requiring oxygen to live carry on the Kerbs Cycle, such as the insect pictured here. This process of biological reactions has its purpose in making it possible for these types of oxygen needing organisms to break down carbs and fats to turn into fuels.

44. Modified Stem of a Plant

A stem modifies in order to extend or provide a more sufficient life for the plant. This plant specifically has adapted its stem to wrap around its environment in order to form a stucture for itself, getting it off the ground safer from non-flying insects.   

43. Calvin Cycle


Taking place in the plant's stroma of the chloroplast, the Calvin Cycle is one that begins with carbon dioxide and goes through this process/cycle to create gluclose.  Carbon fixation, reduction, and regeneration of Rubulose are the steps this process must go through in order to meet its product of sugar molecules used as the plan'ts source of food.

42. Parenchyma Cells

Parenchyma cell's make up most plant's internal tissues and walls of leaves, and both inter an outermost tissues of stems and roots.

41. R-Strategist




R-Strategists are a group of organisms that reproduce early on in life. They produce offspring in large numbers, which generally have short life spans. Examples of these types of organisms include fish and spiders.

40. Stigma and Style of Carpel

The carpel of a flower represents its female reproductive system which is composed of the stigma, ovary, and style. The stigma is the tip in which receives the pollen. This pollen is transported down its tub, the style, leading straight for the ovary so the flower can be fertilized.

39. Cellulose


Cellulose is an organic molecular compound found in abundance in nature. Being composed of carbon, hydrogen, and oxygen it can be located in numerous plants used to strengthen its cell walls. Cellulose has many uses in the food we consume today, with its four main purposes being fiber supplement, appetite suppresser, thickener, and it's ability to prevent sticking. I used a picture of grated parmesan cheese, because within it is cellulose helping to prevent the cheese from getting clumpy and caking.

38. Lipid Used for Energy Storage

Lipids are fats, waxes, or steroids that are insoluble in water, ready to be energy storers. They also contain hormones used to control our metabolism. Being composed of fatty acids, the body must shelve them in specific ways to get the most out of the lipids. Nuts are a good source of lipids as we see in this bag of almonds.

37. Dominant Vs. Recessive

Of course dominant alleles dominate recessive ones, hence its name. In this example, we see a picture of blue eyes and brown eyes. Brown is the dominant allele, while the blue is recessive. Depending on the offspring's parents, the percentage or chances of either blue or brown eyes varies. In my case, my mother has brown eyes, yet still carries the recessive allele for blue, while my father has blue eyes. This gave me and my brothers a 50% chance of getting blue eyes.
