Vegetative cell

Vedclass · Answer

(C) In angiosperms,the pollen grain at the time of shedding is usually $2$-celled,consisting of a larger vegetative cell and a smaller generative cell.When the pollen grain lands on the stigma,it absorbs moisture and nutrients.The vegetative cell (also known as the tube cell) grows out through the germ pore to form the pollen tube.Therefore,the pollen tube develops from the vegetative cell.
