What do we call joining a pollen grain with a ovule?
Of course, it's called 'Pollination'
What do we call the joining of the pollen grain with the ovule?
Pollination.
What makes seeds when combined with a flower's eggs?
This tiny grain is called pollen grain.
How pollen grains reach pistil?
Pollen grains reach the pistil through pollination. The pollen grains are placed on the stigma of the carpal, and it transfers by wind, insects, built in mechanical discharge, and men. When the pollen lands on the stigma, it starts a series of chemical reactions that allow the pollen grain to produce a structure called the pollen tube. At the same time, the generative nucleus divides and produces two sperm nuclei. The pollen grain with the pollen tube and three nuclei is a mature gametophyte. The pollen tube works its way through the style of the carpal and touches the micropyte of the ovule. The sperm nuclei enter the embryo sac and fertilizes the egg and two polar nuclei, referred to as double fertilization. The fertilized egg develops into the immature seed plant, and the central cell develops into the endosperm, or food storage ares, of the seed.

A structure grown by a pollen grain that contains two sperm nuclei is called what?
The structure grown by a pollen grain that contains two sperm nuclei is called the pollen tube. The pollen tube is responsible for delivering the sperm nuclei to the ovule for fertilization in plants.

What is the joining of the male nucleus from the pollen grain with the egg cell in the ovule called?
The joining of the male nucleus from the pollen grain with the egg cell in the ovule is called fertilization. This process results in the formation of a zygote, which eventually develops into an embryo within the seed.
How do the sperms nuclei in a pollen grain reach the egg nucleus in an ovule?
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.

A pollen grain produce a narrow tube called?
The pollen grain produces a narrow tube called the corbicula.
The male sex cell from pollen grain?
The male sex cells from pollen grain are called male gametes.
What is the purpose of the pollen tube?
Pollination is the placement of the pollen on the stigma of the carpal. This pollen transfer can be accomplished by wind, insects, built in mechanical discharge, and man. Once the pollen lands on the stigma, a series of chemical reactions takes place allowing the pollen grain to begin producing a structure called the pollen tube. As this is happening, the generative nucleus will divide and produce 2 sperm nuclei. This pollen grain with the pollen tube and 3 nuclei is considered the mature gametophyte. The pollen tube will work its way through the style of the carpal and touch the micropyle of the ovule. Here the sperm nuclei will enter the embryo sac and fertilize the egg and the two polar nuclei; hence the term double fertilization. The fertilized egg (2N) will develop into the immature seed plant, while the (3N) central cell will develop into the endosperm or food storage area of the seed.
