Cells divide. This makes cells small. Why do cells divide? Why must cells be small? Asexual Reproduction Mitosis Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals? 4 How do little elephants grow up to be BIG elephants?
When animal cells do not get enough oxygen to satisfy the requirements for cellular respiration, how can the cells continue to produce ATP from glucose? Explain. Cellular respiration occurs in all cells. State, with a reason, what type of ...
Why do cells perform mitosis? Why are proteins important to cells? Why do body cells (somatic cells) need to divide and how do they know when to divide? How do plant cells differ from animal cells? What makes an organism alive? Why aren't chloroplasts in animal cells? Why do cells...
"Carry on genes to the next generation" is a reasonable answer, but this is really more an attribute of cells than a function they perform. "Divide into two equal cells" is a defensible reply, too, but this is something cells by definition do at the very ends of their own lives, not...
In many eukaryotic cells, the cell cycle proceeds as a sequence of contingent events. A new cell must first grow to a sufficient size before it can begin DNA replication. Then, the cell must complete DNA replication before it can begin mitosis. Finally, the cell must successfully organize a...
Their generative cell contains a few plastids which, however, are selectively degraded (by an unknown mechanism) prior to division of the generative cell into the two sperm cells in pollen mitosis II. Both mechanisms must be under genetic control of the paternal gamete. Species of...
Why is the whitefish used to study mitosis? Why do we use oil immersion to view specimens under the 100x objective? Why are concave mirrors used in telescopes? Why are protists important? Why was adaptive optics developed? Why is embryology important for doctors? Why are functional MRIs usefu...
