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.
