Why meristematic tissues have lots of cytoplasm, ribosomes and a large nucleus?
Answers
Answer:
Meristematic cells have dense cytoplasmand prominent nuclei because they areactively dividing cells ,so they require cytoplasm and nucleus to control their activities. Vacuole has the function of storing food ,but in meristematic tissue,cells keep on dividing and their is no needof storing anything.
Properties of Meristematic Cells
Cells within meristematic tissues have special characteristics that make them unique when compared to cells in mature, specialized plant tissue. Cells within meristematic tissue are self-renewing, meaning that every time they divide, one new cell remains meristematic, while the second heads off to become a programmed or specialized mature cell.
Additionally, all cells within meristematic tissue are living, while other plant tissue can be made of both living and dead cells. Meristematic cells have thin cell walls, small or no vacuoles, which are stored organelles, and large prominent nucleus. This compares to the thick walls and small nucleus of programmed cells, which also have one or more large vacuoles. Also, meristematic cells contain a significant volume of dense liquid, while specialized cells have only a small quantity of thin liquid.
