Question

short note on plasmodesmata

Answer 1

Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells[2] and some algal cells, enabling transport and communication between them. Plasmodesmata evolved independently in several lineages,[3] and species that have these structures include members of the Charophyceae, Charales, Coleochaetales and Phaeophyceae (which are all algae), as well as all embryophytes, better known as land plants.[4] Unlike animal cells, almost every plant cell is surrounded by a polysaccharide cell wall.
