What is the outermost structure that surrounds and supports plant and fungal cells? A) cell wall B) cytokinesis C) cytoskeleton D) cell membrane

Option A, cell wall

Explanation:

Cell wall is present only around plant cells and other few other organisms such as fungi and bacteria. It provides both structural support and protection the cell.

Cell wall is mainly composed of polysaccharides such as cellulose, hemicellulose and pectin. But in higher plants, it is composed of cellulose only.

Cell membrane is present around animal cells.

Cytoskeleton, composed of protien filaments is present, in the cytoplam of living cell and provide structural framework to the cell.

Cytokinesis is a process of cell division.

So among the given option, option a is correct.

The outermost structure that surrounds and supports plant and fungal cells should be A. Cell wall.
