Modified Root of a Plant

This radish plant is an example of a modified root of a plant. The radish is used to store a significant amount of carbohydrates, the plant uses these carbs as food so the radish is essentially food storage. This plant uses the taproot system where there is on large root with small off shoots, as opposed to the  fibrous root system some other plants use where there are many small roots.

Rhizome

The roots of this Aspen are an example of a rhizome. The roots of this plant are act as a modified subterranean stem that the plant uses to propagate, when the part of the plant above ground is harmed the stem below is still intact making the Aspen very prolific.  One Aspen grove in Utah may have been living over one million years. 

Modified Root of a Plant

The carrot in the picture above is an example of a modified root of a plant. This carrot plant uses the  taproot system, which is where the plant has one large root with smaller branch roots coming off of it. The root and stem of a carrot are used to store large quantities of carbohydrates for the plant also.

Population

This group of daisies are an example of a population because they are a group of the same species who  live in the same area and reproduce together.

Detritivore

This picture is an example of a detritivore, which are organisms that feed and break down dead animals and dead plant matter. The detritivores are very important to the ecosystem because they return the essential nutrients from the dead organisms back into the environment. Detritivores include fungi, insects worms and microorganisms like bacteria and protists.

Introduced Species

Mullen is an example of an introduced species because it is not native to the united states. Mullen originally came here from eurasia in the colonial times because they used Mullen as a medical herb.

The Calvin Cycle

This picture is an example of the calvin cycle although is is too small to see happen in this picture. The calvin cycle is metabolic pathway in the stroma of the chloroplasts in which carbon enters in the form of Co2 and leaves in sugar form.
