Question

a)identify the labelled structures in this figure b)give one function of each of the labelled structures. this is a generalized cell with arrow a pointing to a blue membranous system enclosing a cavity and arrow b pointing to yellow paired cylindrical structures. a - centriole - formation of mitotic spindle; b - rough er - transport of proteins a - smooth er - drug detox; b - cytoskeleton - provide shape to the cell a - rough er - transport of proteins; b - centriole - cell division a - rough er - transport of proteins; b - centriole - spindle formation in cell division and microtubule organization

Explanation:

1. Structure A is a rough endoplasmic reticulum (Rough ER). It has ribosomes attached to its surface and is involved in protein synthesis and transport.
2. Structure B is a centriole. Centrioles play a key - role in spindle formation during cell division and microtubule organization.

Answer:

A. Rough ER - transport of proteins; B. Centriole - spindle formation in cell division and microtubule organization
