Exploring the Fascinating World of Plant Cells

The distinctive features of plant cells include primary cell walls containing cellulose, hemicelluloses, and pectin, the presence of plastids capable of photosynthesis and starch storage, a large vacuole that regulates turgor pressure, the absence of flagella or centrioles (except in gametes), and a unique method of cell division involving the formation of a cell plate or phragmoplast.

Plant cell walls are made of cellulose, hemicelluloses, and pectin.

Plant cell walls differ from the cell walls of fungi (made of chitin), bacteria (made of peptidoglycan), and archaea (made of pseudopeptidoglycan) in their composition.
