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 - 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 enablesurvival of the multicellular plant or animal organism?© BrainMass Inc. brainmass.com October 25, 2018, 1:13 am ad1c9bdddf
Cell membrane: All prokaryotic cells have a cell membrane that safely encloses all the contents. These membranes also act to regulate the import and export of molecules and chemicals in and out of the cell - crucial for allowing key nutrients that the cell needs to surive to enter. It also stops potential toxins from entering the cell. The cell membrane is made up of a phospholipid bilayer. Proteins inpregnated in this bilayer work as gates to allow the transport of components in and out of the cell. Keeps the cell together and ...
This solution discusses cell membranes and ribosomes in prokaryotes as well as the nucleus and mitochondrion in both plant and animal cells (all eukaryotes) in 368 words.
Biology please provide brief answers
1) Explain the importance of a control group in scientific experiments.
2) Briefly discuss the differences between prokaryotic and eukaryotic cells.
5) Discuss how researchers decide that populations of organisms belong to the same biological species?
7) The origin of life on Earth would not have been possible if the primitive atmosphere contained __________.
8) How does energy flow differ from chemical cycling?
10) Briefly describe the difference in the outcomes of mitosis and meiosis. (There is no need to discuss the processes themselves -- only the differences in the end product).
17) What process results in offspring that are adapted to their current environment?
18) What is the difference between a phenotype and a genotype. Does knowledge of an organism's phenotype always allow you to determine the genotype? Why or Why not?
19) Briefly compare and contrast the processes of cellular respiration and photosynthesis.
20) Discuss the validity of the following statement (providing your reasoning): Cutting the tails off mice for 100 generations will result in a strain of mice with genes for short tails.View Full Posting Details
