It can be the source for the whole structure of the work; in that case it is called a generative cell."

The cells subsequently divide and ultimately serve as storage or generative cells.

Gametangia are sexual structures formed from hyphae, and are the generative cells.

The first of the cells (the generative cell) is small and is formed inside the second larger cell (the tube cell).

While this pollen tube is growing, a haploid generative cell travels down the tube behind the tube nucleus.

These new microspore cells then undergo mitosis and form a tube cell and a generative cell.

Cytoplasmic streaming is responsible for movement of organelles and vesicles and of generative cells and vegetative nuclei in pollen tubes.

A microspore undergoes mitosis and cytokinesis in order to produce two separate cells, the generative cell and the tube cell.

Using immunofluorescence, myosin was localized to vesicles, organelles and generative cells and vegetative nuclei in grass pollen tubes [ 39].

As the pollen tube grows the vegetative cell remains in the pollen grain while the generative cell enters the pollen tube and migrates toward the ovule.

GCS1 may also refer to "generative cell specific 1", also called HAP2 (hapless2), a gene of lower eukaryotes which is thought to be responsible for gametes fusion .

In many gymnosperms and all angiosperms, the male gametophytes have been reduced to pollen grains and their antheridia have been reduced to a single generative cell within the pollen grain.

Storage cells contain starch and are multinucleate; whereas generative cells are situated further from the auxiliary cell, are uninucleate, and form the terminal lobes in the ensuing carpospores.

When viruses are transmitted by seeds, the seed is infected in the generative cells and the virus is maintained in the germ cells and sometimes, but less often, in the seed coat.
