Tube cell

Vedclass · Answer

(B) In angiosperms,the pollen grain is typically shed at the two-celled stage,consisting of a vegetative cell (also known as the tube cell) and a generative cell.Upon landing on the stigma,the vegetative cell (tube cell) absorbs nutrients and water,leading to the germination of the pollen grain.The nucleus of the tube cell directs the growth of the pollen tube through the style towards the ovary.Therefore,the tube cell is responsible for the formation and elongation of the pollen tube.
