Kelsea Willenbrock photos 19-26

Modified stem of a plant: this blackberry bush has modified its stem over time so that the thorns discourage predators from harming the plant.

Flower ovary: these blackberries are the ripened ovary from the flower that came before the fruit.

Adaption of a plant:  the thorny edges of this leaf are an adaption to protect the plant.

Autotroph:  plants are autotrophs, meaning that they go through the process of photosynthesis in order to gain nutrients.

Gymnosperm cone: the seed (in the cone) of a flowerless, seed bearing plant, like the pine tree.

Parasitism: parasitism is the relationship between two organisms where one is helped and the other is hurt. For example, the slug that ate this leaf had a tasty meal while the plant suffered from it.

Cuticle layer of a plant: the waxy layer on these leaves helps prevent water loss on the leaves and stem.

Fermentation: fermentation is the process of yeast interacting with sugar to produce ethanol. This is what happens to grapes when they become wine.
