Autotroph (1) 
autotroph

Flowers are examples of autotrophs. Autotrophs are organisms that, unlike heterotrophs, do not feed on other organisms to obtain organic food molecules. Autotrophs, such as plants, undergo the process of photosynthesis and use sunlight, water and carbon dioxide to create their own source of food and energy.

Connective Tissue 
me
Connective tissue is one of four types of tissues a human has. The connective tissue serves a "connecting" purpose. It supports and binds other tissues.There are many types of connective tissue in the body. It adds support and structure to the body. Most types of connective tissue contain fibrous strands of protein that add strength. Examples of this tissue are inner layers of the skin, tendons, ligaments, cartilage, etc.

C4  
grass
A c4 plant adapts in an environment with high daytime temperatures, intense sunlight and drought. A C4 plant is a plant in which the carbon dioxide is first fixed into a compound containing four carbon atoms proir to entering the Calvin cycle or photosynthesis.

Bilateral Symmetry 2 
bilateral
The picture above is of my friend holding a leaf presenting bilateral symmetry. When both sides of this leaf are compared, they are exactly the same -- symmetrical.

Phloem 
phloem
Phloem makes up a part of the transportation system of vascular plants. As the tree gets bigger, it is more difficult to transport nutrients, water, and sugars. Phloem cells are laid out end to end throughout the entire tree, transporting sugars and other molecules created by the plant. Unlike xylem, phloem is always alive. For example, sap dripping out of a tree is a prime example of phloem production.

Xylem 
xylem
Xylem is the system of tubes and the transportation for cells that circulates water and dissolved minerals. Xylem is made of vessels that are connected end to end for the maximum speed to move water. They have a secondary function of support, as well. For example, once a tree is cut down, the xylem is the set of rings. The rings of the xylem reveal the amount of years the tree was alive.

Carpel of a Flower 
floahhh
The carpel is the stalk in the middle of the flower. it is the female part of the flower. The carpel has three parts: stigma, style, and the ovary. The stigma is where the pollen has to land. Below the stigma is the style and the ovary which is where seeds are formed.

Krebs Cycle 
petls
The Krebs Cycle is a part of aerobic respiration. In this form of respiration, ATP is produced. Krebs Cycle also produces electron carriers called "NADH" which creates an electron transport chain. This chain regenerates NAD. In this transport chain, energy is the final product in the form of ATP. ATP is a form of energy that drives the metabolic process.

Ethanol Fermentation (alcohol) 
alcohol
Ethanol fermentation is a process where sugars like glucose, fructose, and sucrose produce ethanol and CO2. Alcohol fermentation process is carried out by teast cells using enzymes. Alcohol remains in the liquid which is great for making an alcoholic beverage -- but not for the yeast cells. The yeast cells die when the alcohol exceeds its tolerance level.

Fermentation (bread) 
bread
The fermentation process can be found in bread. It serves three primary purposes: to produce CO2 gas to create a light and airy texture in the bread, to enhance the flavor of the bread, to change the protein structure of the bread to prevetn a chewy texture. Also, the fermentation process is the time during which the yeast converts the sugar present in the flour and the dough into CO2 and alcohol.
