Question

(a)what is meristematic tissue? name different types of meristamatic tissue and their function.
(b)how simple permanent tissues are different from complex permanent tissues?

Answer 1

a) There are two types of apical meristem tissue: shoot apical meristem (SAM), which gives rise to organs like the leaves and flowers, and root apical meristem(RAM), which provides the meristematic cells for future root growth. ... Furthermore, the cells are small and protoplasm fills the cell completely.
b) Complex permanent tissues are comprised of two or more types of cell in combination, usually with a complex structure that makes the cells interact with one another (otherwise they would probably be considered different tissues). Xylem and phloem are the two major types of complex permanent tissues.
