Study Notes

Plant Cell Structure

Plasmodesmata allow materials to pass from the cytoplasm of one plant cell to the cytoplasm of an adjacent cell.
The cell wall is the extracellular structure that distinguishes plant cells from animal cells.
There is no key role of collagen in plant tissues, as collagen is a protein found in animal connective tissue.
The main component of the plant cell wall is cellulose.
Plasmodesmata facilitate the exchange of molecules between adjacent plant cells.
The apical surface of a cell is involved in secretion and absorption.
Plant cells are distinguished from animal cells by the presence of a cell wall, which is composed of cellulose.
