Question

1. Give the significance of cellular differentiation in
multicellular organisms.
2. Why the xylem is called a compound tissue?​

Answer 1

Answer:

1.Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. ... Differentiationdramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals.

2.When a plant tissue is made up of many kinds of cells, all working in coordination for a common main function we call thetissue as complex tissue. Xylem and Phloem are complex because they are made different cells, with different roles.
