The nucleus in each cell in the stem of a plant contains 32 chromosomes How many chromosomes are there in the nuclei of its pollen grains?
Pollen grains are produced via meiosis, which halves the chromosome number. Therefore, the pollen grains would contain 16 chromosomes.
How many chromosomes does a peanut have?
Peanuts have 40 chromosomes, with 20 coming from the male parent (pollen) and 20 from the female parent (ovule).
Does the pollen come from a male or female part of the flower?
The 'pistil' is a female part of a flower. However flowers usually have both male and female parts, it is unusual for a plant to be just male or female (although there are examples such as 'holly' and 'cannabis').
How many chromosomes in a pollen cell?
This is an impossible question to answer the way it is phrased. One needs to know what plant species is being discussed before the question can be answered. Each species will have a unique number of chromosomes and its pollen will have half as many as the parent species.
In seed plants the sperm make it to the egg via?
By swimming in watery fluid through the neck of archegonium the sperm reaches to the egg in seedless plants.
How many chromosomes are there in the male nucleus in a pineapple pollen grain?
There are 50 chromosomes in both male and female pineapple pollen grain.
How the nucleus from a pollen grain fertilizers a female egg cell?
How the nucleus from a pollen grain fertilize a female egg cell
How nucleus from a pollen grain fertilize a female egg cell?
How the nucleus from a pollen grain fertilize a female egg cell
The nucleus in each cell in the stem of a plant contains 32 chromosomes How many chromosomes are there in the nuclei of its pollen grains?
Pollen grains are produced via meiosis, which halves the chromosome number. Therefore, the pollen grains would contain 16 chromosomes.
How the nucleus form a pollen grain fertilize a female egg cell?
During pollination, the male nucleus in a pollen grain is transferred to the female egg cell within the ovule of a plant. This transfer is facilitated by a pollen tube that grows from the pollen grain to the ovule. Once the pollen tube reaches the egg cell, the male nucleus fuses with the female nucleus to form a zygote, which eventually develops into a new plant embryo.
How the nucleus form a pollen grain fertilizers a female egg cell?
by raping it
How many chromosomes does a peanut have?
Peanuts have 40 chromosomes, with 20 coming from the male parent (pollen) and 20 from the female parent (ovule).
Does the pollen come from a male or female part of the flower?
The 'pistil' is a female part of a flower. However flowers usually have both male and female parts, it is unusual for a plant to be just male or female (although there are examples such as 'holly' and 'cannabis').
Does pollen have a nucleus?
Yes, pollen grains have a nucleus. The nucleus contains the genetic information necessary for the pollen to fertilize a plant's ovule.
How many chromosomes would a pollen grain have to compare to an ovule?
Half of the individual cell of ovule except female gametophyte cells
How does the pollen tube nucleus function in fertilization?
The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary
What does a pollen grain and ovule each contain?
Pollen grains contain the male gametes required for sexual reproduction of a plant/ flower. These are haploid, and only contain half the full set of chromosomes; the other half is contributed by the female gamete (or ovule).A grain of pollen contains:a larger vegetative cell (also called the tube cell) inside of which is aa smaller germ cell (also called the generative cell).The pollen grain "germinates" on the stigma of the receptive flower and grows down the style, once it reaches the ovule the germ cell/ nucleus fuses with the nucleus of the ovule and an embryo is formed
