This remarkable capacity, until now a puzzling phenomenon, is fully expressed when plant cells are cultured in vitro , allowing the regeneration of new plants completely modeled on their mother plant. The finding that transition from mitosis to meiosis may occur in cultured plant cells, and ...
What are examples of somatic cells? The term somatic cells refers to any type of cells that contain the diploid number of chromosomes. Examples include nerve, blood, muscle, and bone cells. How many types of somatic cells are there? There are over 220 types of somatic cells, each having ...
It also indicated that it was possible for the DNA in differentiated somatic (body) cells to revert to an undifferentiated embryonic stage, thereby reestablishing pluripotency—the potential of an embryonic cell to grow into any one of the numerous different types of mature body cells that make ...
The water-conducting cells that make up the xylem are nonliving. The accumulated xylem often forms annual rings composed of two zones: a relatively wide zone of spring wood (made up of large cells, characteristic of rapid growth) and a narrower zone of summer wood (smaller cells). Such ...

What is the purpose of crossing over? When and in what types of cells does crossing over occur?Cell Cycle:The cell cycle is the process where the cell divides, proliferates, and matures into a new cell. During this process, the cell undergoes several phases ...

Fat cells, also called adipocytes, are a major cell component ofadipose tissue. Adipocytes contain droplets of stored fat (triglycerides) that can be used for energy. When fat is stored, its cells become round and swollen. When fat is used, its cells shrink. Adipose cells also have a criti...
