Why germination of cms pollen is low?
Cytoplasmic male sterile pollen is generally devoid of metabolic activities hence not capable of germination.
Why sterile pollen do not take acetocarmine stain?
Acetocarmine stains chromosomes and sterile pollen must lack them.
Which is not an example of cytoplasmic inheritance?
sterile pollen
What is produced by anther?
Male pollen grains
What are reproductive cells in the pollen?
Pollen are male sex cells. So they contain sperms.

What does pollen carry in the male flower?
Pollen is the male plant's reproductive cells (sperm).
The male sex cell from pollen grain?
The male sex cells from pollen grain are called male gametes.
What is produced by anther?
Male pollen grains
Does pollen come from the male or female part of the flower?
Pollen comes from male part of the flower.
What are reproductive cells in the pollen?
Pollen are male sex cells. So they contain sperms.
What is the male part of the plant that produces pollen called?
The male part that produces pollen is the Stamen, The female part with pollen receptors, is the stigma.
What is barnase-barstar system?
Barnase is a ribonuclease expressed by the bacterium Bacillus amyloliquifaciens. It degrades RNA at the GpN site and thus chews up all RNA. Barstar is a protein that blocks Barnase activity by binding to its active site making it thus unavailable for RNA degradation. Barnase -Barstar system is being used widely to develop male sterile lines. The Barnase gene in the male sterile plants are expressed under the control of a tapetum specific promoter. Thus expressed Barnase in the tapetum degrades tapetal RNA and makes the pollen sterile. The introduction of the Barstar expressing cassette in this system blocks the Barnase protein and thus restores fertility of the pollen.
What is a pollen tube?
A pollen tube is part of the male gametophyte of seed plants. It acts as a conduit to transport the male gamete cells from the pollen grain
What sentence can you give me with the word pollen?
The bees can transport pollen. Pollen is very male and very sexy.
