In cytokinesis, how are the internal organelles 'distributed' to each daughter cell? Consider mitochondria in eukaryotic cells....
Homework Answers
During cell division, segregation of cell organelles first begins at metaphase and continues till the organelles are distributed by the completion of cytokinesis. Golgi stacks redistribute between the two daughter cells such that both have very similar golgi stack densities. Most cell organelles like, endoplasmic reticulum, centrioles, lysosomes and endosomes etc,become dispersed or fragmented during the stages of cell division and then during cytokinesis, segregate and reassemble in the two daughter cells.
Organelles like mitochondria and plastids [ only in plant cells], have their own DNA. Therefore, they make copies of themselves, which get distributed between the two daughter cells. It is believed that mitochondria remains intact during the entire process of cell division, most probably to provide energy required by the cell. So, plastids and mitochondria do not disperse or fragment, instead they make copies of themselves and get distributed between the two daughter cells.

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...

Read the following: Erythrocytes (red blood cells) have no nuclei, mitochondria, or other organelles when they are mature. These organelles are ejected when the erythrocyte enters the bloodstream or shortly thereafter. Post a paragraph that addresses the following: Should erythrocytes still be considered eukaryotic cells? Explain your rationale. What do you predict would be the effects of having no nucleus? Explain. In erythrocytes, the lack of mitochondria is an advantage. Why do you think this is true? Explain.

Question 19 (Mandatory) (2 points) Saved How is plant cell cytokinesis different from animal cell cytokinesis? The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase. The structural proteins of plant cells separate the two...

Directions: Mitochondria are organelles that supply most of the energy that cells require. Recently, scientists have discovered that mitochondria are also important in apoptosis: programmed cell death or cell suicide. If a cell starts growing abnormally, this can trigger the death of the cell. It is a natural defense that we have against cancer. Some cancer cells have special proteins in their mitochondria that prevent this apoptosis and allow the cancer cells to survive. Submission: Look for more information on...

Question 2 How is a protein targeted to the matrix of mitochondria in a eukaryotic cell? Describe the “travels” of a newly transcribed polypeptide as it goes from ribosome to its destination in the matrix. (Hint: the words “contact site” should occur somewhere in this description if your polypeptide is traveling the right path.)
