In an angiosperm, how many microspore mother cells are required to produce 100 pollen grains? View Solution How many microspore mother cells are required to produce 80 male gametes in angiosperms View Solution View Solution View Solution View Solution ...
Pollen grains are, in essence, plant sperm. Or perhaps more technically, sperm sedans. Inside, they contain the male gametes, which is the portion of DNA needed for plant reproduction. There are many unique adaptations to help the pollen get where it needs to go -- namely, its own species...
flower and/or fruit or seeds.A flower is the part of the plant that makes the seeds.The main parts of a flower are the carpels and stamens.These parts are often found in the center of the flower.There are egg cells in the carpel and pollen cells in the stamen.All flowers have ...

How do cells created through meiosis differ from somatic cells? In the diploid stage, how are there gametes when there is only one set of chromosomes (n)? What is the difference between somatic cells and gametes? How many sex chromosomes are in a human gamete?
How does the stamen release sperm in pollen?Sexual Reproduction in Plants:While many plants are able to reproduce asexually, producing genetically identical copies of themselves, sexual reproduction is what allows them to evolve over time. The most advances plants, the angiosperms, use flowers to ...

In recent years, the local high temperature climate in the world has brought a certain impact on the rice industry, and the abiotic stress factor of high temperature has had to be highly valued. High temperature has many effects on plants, including but not limited to shortening the plant ...
cells when terminally differentiated: a vegetative cell that develops a tip-growing pollen tube to deliver the two sperm cells to the ovule. However, the apparent structural simplicity of the male gametophyte underlies a highly complex life history. Pollen tubes change neighbors throughout their life...
in the calculation: taxonomic family, body size category, pollen selectivity (oligolectic, polylectic, parasitic), foraging range and proboscis length. As a second step, we calculated the ecological similarity and rarity of species in the wild bee community per grid cell using community-weighted ...
