You are using a computer program to design a new single-celled organism. Discuss why a flat, plate-like cell will be more efficient in transporting materials than a spherical, ball-like cell of the same volume.
Use the analogy of the cell as a manufacturing factory to describe the function of the following cell structures: plasma membrane, mitochondria, nucleus, Golgi, ribosomes, lysosomes, endoplasmic reticulum.
True or False
Cell walls are present in the cells of archaea, bacteria, algae, fungi, and plants only.
Photosynthetic unicellular prokaryotes such as Oscillatoria exhibit a green color when viewed under a microscope because of the presence of numerous chloroplasts.

- A cell is moved from its normal environment in a freshwater river and is suddenly placed into the ocean. What would be the effect of this change in environment on the cell? O 1) It would shrivel because it would lose water. O 2) It would shrivel because it is responding to a hypotonic environment. O 3) It would swell because it is experiencing a hypertonic environment. O 4) It would swell because it would gain water. O 5) Nothing would happen to the cell.arrow_forwardChoose TWO of the cell structures from the list provided.

- You observe organelles moving within the cytoplasm of a cell and conclude that this movement must be associated with either microtubules or actin filaments. The reason that intermediate filaments could not be associated with this motility phenomena is because _________? They are not intrinsically polar The cell can not control their assembly They are found only at certain cell junctions They can not interact with membranes They can not disassemblearrow_forwardYou are studying a plant and inject fluorescein, a fluorescent dye, into a single cell on the surface of the plant. After a brief period of time, the dye spreads to cells neighboring the injected cell. What do you conclude? only one options: The cells are connected by the cell wall. The cells are connected by tight junctions. The cells are connected by gap junctions. The cells are connected by plasmodesmata.arrow_forwardYeast are unicellular microorganisms that use sugar as a food source to produce energy for growth. Yeast cells can convert sugar to energy in the presence or absence of oxygen. When in the absence of oxygen, sugar is broken down into carbon dioxide and alcohol. The sugar molecules cannot pass through the cell membrane directly due to their large size. For the yeast to acquire sugar, the cell must use a transport protein to move the sugar into the cell. Sugar molecules enter the cell with a hydrogen ion. This process continues if there are sugar and hydrogen ions present in the environment. The cell uses the ATPase enzyme shuttle to remove the hydrogen ions from the cell. The image shows this transport process in a yeast cell. Why are active and passive transport both required to move sugar? The active transport process provides the concentration gradient necessary to allow alcohol to help move hydrogen ions into the cell. The active transport process provides the concentration gradient…arrow_forward
