What are Stalks that form pollen?
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
What is the size and the pollen grains?
The size of pollen grains can vary depending on the plant species, but most are typically between 10 to 100 micrometers in diameter. Some larger pollen grains can reach up to 200 micrometers. Pollen grains are microscopic structures produced by seed plants for reproduction.
What do flowers produce?
A flower produce pollen sacs which has pollen grains in it
What the function of the pollen grains?
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.
What are grains that produce sperm cells called?
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
Is pollen grains released from a flower reproduction?
Yes
Which is true statement about conifer?
Conifers release pollen grains.
Is this reproduction pollen grains are released from a flower?
Yes because the pollen then will later produce more and provide which is considered reproduction in term.
During sexual reproduction in a flowering plant microspores produce?
During sexual reproduction in a flowering plant, microspores produce pollen grains through the process of microgametogenesis, which involves the formation of male gametophytes. These pollen grains contain the male gametes, or sperm cells, that are essential for fertilization when they are transferred to the ovule of a flower.
What is a saccus?
A saccus is a bladder-like structure found on the pollen grains of many species of conifer.
A conifer that has both male and female cones will produce many more pollen grains than ovules How does that help the conifer reproduce?
The wind usually scatters the pollen grains of conifers. The likelihood of pollen reaching female cones is increased when there are large amounts of pollen.
What is the correct order in which these structure form during the plant reproduction process?
Pollen grains are produced in the anther of the flower. Pollen grains are transferred to the stigma of the flower. A pollen tube forms and grows down through the style towards the ovary. Fertilization occurs when the sperm cells in the pollen reach the ovule in the ovary.
What is the function and parts of the stamen?
The stamen provides pollen grains and male gametes are released from pollen grains during pollen germination and fertilization
Why do conifers produce more pollen than grains used to fertilize conifer eggs?
Because conifers are pollinated by wind hence to ensure fertilization of each egg clouds of pollen grains are formed.
Pollen grains develop in what?
Pollen grains are often called as microspores or male gametes. They are produced in pollen sacs present in pollen chambers in the anthers of the flower. They are produced due to repeated division of microspore mothercells and are haploid (n).
Is a rock disintegrates by chemical weathering into small grains of similar composition considered reproduction?
No, the disintegration of a rock through chemical weathering into small grains of similar composition is not considered reproduction. Reproduction involves the creation of new individuals that are similar to the parent organism, which is not the case in the scenario you described.
If a rock disintegrates by chemical weathering into small grains of similar composition, would this be considered reproduction?
No, disintegration of a rock by chemical weathering into smaller grains is not considered reproduction. Reproduction involves the creation of new individuals through biological processes like budding, fission, or sexual reproduction. Weathering only involves the breakdown and alteration of existing materials.
