How does the egg of a flower become fertilized?

Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.

What part the pollen grains are initially located?

Pollen grains are produced by meiosis of microspore mother cells that are located along the inner edge of the anther sacs (microsporangia). The outer part of the pollen is the exine, which is composed of a complex polysaccharide, sporopollenin.

What gives rise to pollen grains by the process of meiosis?

Pollen development occurs in a structure called the microsporangium (micro = small), located within the anthers. Within the microsporangium, the diploid microspore mother cell divides by meiosis to give rise to four microspores, each of which will ultimately form a pollen grain, illustrated below.

Where a pollen grain is dropped to fertilize an ovule is sticky?

The top of the pistil is called the stigma, which is a sticky surface receptive to pollen. The bottom of the pistil contains the ovary and the narrowed region in between is called the style. The male contribution or pollen is produced in the anther, and seeds develop in the ovary.

What is another name for Microsporangia?

What is another name for microsporangia? Male Gametophyte Cell: Generative cell.. what does it produce?

What is the difference between Microsporangium and anther?

As nouns the difference between anther and microsporangium is that anther is (botany) the pollen-bearing part of the stamen of a flower while microsporangium is (botany) a case, capsule or container that holds microspores.

What is the other name of pollen sac?

The typical anther is bilocular, i.e. it consists of two thecae. Each theca contains two microsporangia, also known as pollen sacs. The microsporangia produce the microspores, which for seed plants are known as pollen grains.

Is pollen a Microspore?

Pollen is same as microspore.

What is difference between the Microspore and pollen grain?

The main difference between microspore and pollen grain is that the microspore is a small spore in land plants, which develops into the male gametophyte whereas the pollen grain is a fine granule in seed plants, consisting of a reduced male gametophyte.
