Difference Between Vegetative and Generative Cell

The main difference between vegetative and generative cell is that vegetative cell produces a tube cell whereas the generative cell produces two sperm cells during the pollen development. ... Moreover, vegetative cells are non-reproductive while generative cells are reproductive.

What is the role of vegetative cell and generative cell?

The generative cell undergoes a second mitosis to generate two sperm cells. The vegetative cell forms the pollen tube that delivers the sperm to the embryo sac. One sperm cell fertilizes the egg to produce the zygote, and the second sperm cell fuses with the central cell to produce the endosperm (3).

What is generative cell?

A cell of the male gametophyte (pollen grain) of seed plants that divides to give rise directly or indirectly to sperm. ... See more at pollination.

What is vegetative cell?

Definitions of vegetative cell. noun. any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes. synonyms: somatic cell.

Is vegetative cell is larger than generative cell?

Vegetative cell is larger than generative cell. ... When pollen is shed at two celled stage, double fertilization does not take place. Answer Verified. Hint: Pollen grain gives rise to the tube of pollen that absorbs nourishment for its production from the style cells.

What do vegetative cells do?

A cell of a bacterium or unicellular alga that is actively growing rather than forming spores. 'These bacteria exist either as spores or as vegetative cells.

What is the function of vegetative nucleus?

one of them, the so-called vegetative, or tube, nucleus seems to direct the operations of the growing structure. The other two, the generative nuclei, can be thought of as nonmotile sperm cells. After reaching an ovule and breaking out of the pollen tube tip, one generative nucleus unites with the…

Where is generative cell found?

During division the generative cell is located in the centre of the pollen grain, near to the nucleus of a surrounding vegetative cell.

What is the ploidy of generative cell?

The generative cell divides by mitosis to produce two haploid sperm cells. The pollen tube reaches the micropyle of the ovule and digests its way into one of the synergids, releasing the sperm cells. The synergid degenerates as one of the two sperm cells fertilizes the egg cell, producing a diploid (2n) zygote.

What is Micro Sporogenesis?

What is microsporogenesis? Microsporogenesis is the process by which extremely tiny spores are formed in the pollen sacs of seed plants. They eventually develop into pollen grains, which are dispersed and help the plant reproduce.

Do vegetative cells contain DNA?

The endospores are structurally, metabolically and functionally very different from bacterial vegetative cells.

Difference between Bacterial Endospores and Vegetative Cells.

What is vegetative nucleus?

(vegetative cell) The large nucleus formed within the pollen grain of angiosperms along with one or two smaller generative nuclei. ... It is thought to control the growth and development of the pollen tube and disintegrates when the pollen tube penetrates the nucellus.

Are vegetative cells heat resistant?

Although pasteurization is known to inactivate the vegetative cells, spores of B. cereus are known to be highly heat resistant and are usually unaffected by physical, chemical and biological factors (Gaillard et al. 1998; González et al. 1999).
