Bacterial cells are prokaryotic. Select two structures of bacterial cells and briefly describe them; what do they look like, what are they composed of? Then, explain how these two structures allow bacterial cells to survive as unicellular organisms.
There are many examples of eukaryotic cells. Algae, Fungi, Plants, and Animals are all composed of eukaryotic cells. Some algae and fungi are unicellular organisms, but other algae and fungi, and all plants and animals are multicellular organisms that are composed of specialized eukaryotic cells that interact to support the life of the multicellular organism.
Choose either a plant or an animal cell. Choose two structures or organelles of the cell (not used in part one above.) Describe these two structures or organelles â what do they look like, what are they composed of? Then explain how these plant or animal cell structures or organelles function. How do these functions support activities of the plant or animal cell and enable survival of the multicellular plant or animal organism?
Be sure to state how the structures in the eukaryotic cells ALSO contribute to the life of the entire organism and not just the cell. Listen to the chat for examples of what is meant by this.
Cellular Respiration and Photosynthesis co-exist as paired metabolic processes.
Photosynthesis uses light energy to convert carbon dioxide into glucose, a simple sugar, in two steps, the light dependent and light independent reactions. Oxygen is produced as a by product during photosynthesis. This reaction stores energy in the chemical bonds of glucose.
Sugar and other carbohydrates are used as fuel sources by cells. During the process of Aerobic Cellular Respiration, glucose is broken down using oxygen. This reaction releases energy which is used to create ATP molecules, the energy carrier molecule of cells. The process also releases Carbon Dioxide as a byproduct.
