Is pollen N or 2n?

Is pollen N or 2n?

(b) Anther- It is the part of the stamen where pollens are produced. It is the male part of the flower and it contains pollen grains. It is diploid in structure (2n).

Which letter represents the flower structure that makes it possible for it to attract pollinators?

Letter “A” represents showy parts that can attract insects. Letter “B” represents parts of the plant that protect the flower bud and are underneath/behind the petals. Letter “C” represents the female organ of the plant. Letter “D” represents the male organs of the plant.

Where does the pollen grain formed in a flower?

anther
In flowering plants, pollen grains are formed with the anther. If you look at the diagram to the right, you will see that the anther is a part of the stamen. Essentially, the anther is where the pollen grains are produced!

Where does pollen formation occur?

Formation. Pollen is produced in the microsporangia in the male cone of a conifer or other gymnosperm or in the anthers of an angiosperm flower. Pollen grains come in a wide variety of shapes, sizes, and surface markings characteristic of the species (see electron micrograph, right).

Is the pollen haploid or diploid?

Pollen is the haploid microgametophyte generation in seed plants and is considered the male partner in sexual reproduction. In flowering plants pollen comprises either two or three cells when shed from the flower.

Where are pollen grains formed in the anther sac?

Pollen grains are the male gametes. These are formed in the anther sac, by meiosis cell division each microspore mother cells produces four microspores or pollen grains. Answer verified by Toppr

How is Pollen formed in a flowering plant?

Pollen Formation In coniferous plants, pollen is formed in the microsporangia of the male cone, whereas it is produced in the anthers of flowering plants (also termed angiosperms). Each microsporocyte is diploid and forms four haploid cells, termed microspores, via meiosis. This process is termed microsporogenesis.

What is the meaning of the word pollen?

Pollen Definition. Pollen refers to the powdery product synthesized by seed plants responsible for the production of the male gametes of the plant (shown below).

When does the pollen grain land on a receptive stigma?

When the pollen grain lands on a receptive stigma it grows into an elongate pollen tube containing a tube nucleus and a generative nucleus, the latter of which divides into two sperm nuclei. A binucleate angiosperm pollen grain containing a generative nucleus and a tube nucleus.
