If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a ...
What does nucleus mean cell? In cell biology, the nucleus is the large, membrane-bounded organelle that contains the genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. In cell biology, the nucleus function is to act asthe control center of...
When the vacuole losses water (and the plant does not absorb water), turgor pressure is lost, the vacuole pulls the cytoplasm and thus the cell membrane away from the cell wall, causing the plant to start wilting and eventually die.
What is the role of the nucleus in cell division? The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process ...
A Structure Unique to Plant Cells Plant cells are the only cells which have a cell wall. The cell wall surrounds and protects each cell, with a very rigid and firm structure. This allows plants to maintain their height and keep their shape. ...
