The anaphase takes only a few minutes to complete, making it the shortest of the five phases of mitosis. Despite the short duration, the phase consists of two parts known as anaphase A and B.
During the first part of anaphase, the sister chromatids split apart and start their journey to two opposite poles of the cell. The spindles are shortened at this point. During late anaphase, the chromatids reach the opposite poles, which then move farther apart from one another to ready the cell for the final stage of mitosis known as telephase. At this point, the cell contains eight chromosomes.Learn More
An ionotropic receptor is a molecule in a cell membrane that can open or close a channel into the cell. When the ionotropic receptor is open, small particles called ions can travel into or out of the cell.Full Answer >
Endocytosis and exocytosis are similar because they both allow patches of the membrane to flow from one compartment to another. According to Pearson Education, both processes require the cell to be dynamic instead of static.Full Answer >
Euglena gracilis is a tiny, single-celled organism with a long, oval body, tail-like flagella and chloroplasts for producing food energy from sunlight. Although they photosynthesize like plants, they are able to swim using their flagella and eat other organisms. They are classified as protists rather than as animals or plants.Full Answer >
Examples of single-celled organisms include species in the Kingdom Protista, the Kingdom Monera and a few representatives of the Kingdom Fungi. Monera includes both conventional bacteria, called eubacteria, and a very strange group of organisms known as archeobacteria.Full Answer >
