Auxin producing area of a plant

The auxin is a plant hormone that causes the elongation of cells in plants. It regulates plant growth and is found in new shoots or buds on leafy plants. Auxin can be found in the stem tip as shown on this flowery tip.

Autotroph

An Autotroph is any organism that has the ability to form oxygen and glucose. This tree is an example because it goes through photosynthesis and produce oxygen and glucose.

ATP

ATP is part of photosynthesis and cellular respiration. The plants will produce glucose through sunlight and then animals will consume the glucose to create ATP. The plant pictured is producing glucose for an animal to eat and to continue on the process. ATP is energy that every living utilizes in daily processes.

Asexual reproduction

Asexual reproduction is the reproduction from one parent only. The offspring inherit all of the traits from its parent, becoming an exact replica of its parent. The strawberry patch that I have pictured above has spread the same way, the parents produce shoots that start a new plant.

Archaebacteria

Archaebacteria is a domain of a single celled microorganism. These microbes are prokaryotes, meaning they have no nucleus. Many archaea thrive in extreme conditions such as hot sulfur pools or in minerals and rock deep inside the earth. As the boiling water above represents these harsh conditions that the archaebacteria can live in. They even found a new group of archae in an acid mine drainage, they called it arman.  

Anther and filament of stamen

The stamen is the male reproductive part of a flower. It produces pollen, and consists of the anther and stalk. The anther is the sac in which pollen grains develop and is located at the stamen's tip. The filament is the stalk that supports the anther. The flower I have pictured has small filaments and anthers that are hard to see but you can kinda see it in the very bottom flower. The pollon on the anther will spread by animals and wind to other flowers. 

Animal with a segmented body

A segmented body is a division of an animal's body plan. There are 3 different sections, whether individually or together with other segments. The sections are called the head, thorax, and abdomen. The dragonfly pictured has a segmented body.
