The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
no. sugar grains are smaller than salt grains
A transverse section of the anther reveals four areas of tissue capable of producing spores. These tissues are composed of microsporocytes, which are diploid cells capable of undergoing meiosis to form a tetrad (four joined cells) of haploid microspores. The microspores become pollen grains and may eventually separate.

The cells found in the human body are eukaryotic cells. Organisms that have eukaryotic cells are usually multicellular like humans. Organisms that have prokaryotic cells are usually unicelluar, like bacteria.
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.

Animal cells that are capable of meiosis are typically diploid, meaning they have two sets of chromosomes. During meiosis, these diploid cells undergo two rounds of cell division to produce haploid gametes with only one set of chromosomes.
Generally, a somatic cell in a human body has 46 chromosomes, which are two complete sets of 23 chromosome pairs. Because they have two sets, these cells have a ploidy level of diploid.
The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
For biology class, we have to create a cereal box that deals with cells. I can't think of a name to call my cereal. Can you please help me? It could either be plant or an animal cell. What would be a catchy cereal name that has something to do with cells in it?
At the end of mitosis, the ploidy of the cell remains the same as it was at the beginning of the process. This means that the daughter cells produced from mitosis are genetically identical to the parent cell and have the same number of chromosomes.
Human cells are typically diploid, meaning they have two sets of chromosomes - one set inherited from each parent. However, gametes (sperm and egg cells) are haploid, containing only one set of chromosomes.
No, the ploidy of a cell does not change during mitosis. Mitosis is a type of cell division where a cell divides to produce two daughter cells with the same number of chromosomes as the parent cell. This ensures that the ploidy (number of sets of chromosomes) remains the same in the daughter cells.
Ploidy reduction is a process in which the number of sets of chromosomes in a cell is reduced. This can happen during meiosis, the process of cell division that produces gametes (sperm and egg cells) with half the normal number of chromosomes. Ploidy reduction is important for sexual reproduction to maintain the correct chromosome number in the offspring.
The grains that produce sperm cells in plants are called pollen grains. These grains contain the male gametes and are produced by the male parts of the flower.
