The plant body consists of many different types of cell, each enclosed in its own cell wall and united with other cells by means of a cementing intercellular sub-stance. Within this united mass certain groupings of cells are distinct from others structurally or function-ally or both.

31 paź 2023 · Mature pollen grains contain two cells: a generative cell and a pollen tube cell. The generative cell is contained within the larger pollen tube cell. Upon germination, the tube cell forms the pollen tube through which the generative cell migrates to enter the ovary.
Each carpel has an ovary at the base where ovules are housed. The style emerges from the ovary and is topped by the stigma . Pollen grains land on the stigma and must grow a tube down the style to reach the ovule and complete fertilization.
