How are the tapetal cell in microsporangium binucleate?
The tapetal cells in the microsporangium are binucleate because they contain two nuclei per cell. These nuclei are essential for the functions of the tapetal cells in nourishing and supporting the developing pollen grains. The presence of two nuclei allows for synchronized and coordinated activities within the tapetal cells during pollen development.
What will happen if a cell does not divide?
If a cell does not divide, it may become too large and have difficulty obtaining nutrients and disposing waste effectively. This can lead to cell stress or death. In some cases, cells may enter a dormant state called G0 phase where they remain alive but do not actively divide.
What is cytokinsis?
Cytokinisis is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. It is the division of the cytoplasm. It usually initiates during the late stages of mitosis, and sometimes meiosis, splitting a binucleate cell in two, to ensure that chromosome number is maintained from one generation to the next.
What is an aeciospore?
An aeciospore is a binucleate spore of a rust fungus, formed in a chainlike series in an aecium.
How is the binucleate condition of liver cells explained?
The binucleate condition of liver cells is due to incomplete cytokinesis during cell division, resulting in the retention of two nuclei in a single cell. This allows for continued cell function and growth without the need for increased cell division. It is a unique adaptation that helps liver cells maintain their metabolic functions.

What is an example of a binucleate cell?
An example of a binucleate (containing two nuclei) cell is a cardiomyocyte, a muscle cell found in the heart. Cardiomyocytes can have two or more nuclei to support their large size and contractile function.
If a cell undergoes mitosis but not cytokinesis the product is?
The product would be a cell with two nuclei, resulting in a binucleated cell. This can often be found in certain cancer cells and is known as a bi/multinucleated cell.
How is secondary mycelium formed?
Commonly, the dikaryotic mycelium is produced by fusion of monokaryotic hyphae from different mating types. resulting in formation of a dikaryotic(binucleate), or secondary mycelium because karyogamy does not immediately follow plasogamy.
What will happen if a cell does not divide?
If a cell does not divide, it may become too large and have difficulty obtaining nutrients and disposing waste effectively. This can lead to cell stress or death. In some cases, cells may enter a dormant state called G0 phase where they remain alive but do not actively divide.
Does independent assortment provide new genetic combination?
Cytokinesis,from the greek cyto- (cell) and kinesis (motion, movement), is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. It usually initiates during the late stages of mitosis, and sometimes meiosis, splitting a binucleate cell in two, to ensure that chromosome number is maintained from one generation to the next. In animal cells, one notable exception to the normal process of cytokinesis is oogenesis (the creation of an ovum in the ovarian follicle of the ovary), where the ovum takes almost all the cytoplasm and organelles, leaving very little for the resulting polar bodies, which then die. In plant cells, a dividing structure known as the cell plate forms across the centre of the cytoplasm and a new cell wall forms between the two daughter cells.

If a cell undergoes nuclear division but not cytoplasmic division the product is a?
The product is a multi-nucleated cell. In the early Drosophila embryo, for example, the first 13 rounds of nuclear division occur without cytoplasmic division, resulting in the formation of a single large cell containing 6000 nuclei. Nuclear division without cytokinesis also occurs in some types of mammalian cells. Osteoclasts, trophoblasts, and some hepatocytes and heart muscle cells are multi-nucleated.. You're welcome -Scott
What are the three stages of prenatal development?
24 hours after fertilization:the single celled egg has split into two identical sister cells32 hours after fertilization:the two identical sister cells have divided into four cells36 hours after fertilization: the egg has divided into eight cells4 days after fertilization: embryo enters the uterus at the morula stage of development6-7 days after fertilization:the egg enters the blastula stage7-8 days after fertilization:the blastula hatches from the pelucida2 weeks after fertilization: the blastocyst elongates and comes in contact with the uthrine wall14-16 days after fertilization: binucleate cells begin to differnentiate in the trophoblast16 days afer fertilization:20 days after fertilization: the embryo's heart begins to beat30 days after fertiliziation: the embryo is about a ½ inch long31-42 days after fertilization:major growth is taking place42 days after the fertilization:the embryonic period is at an end and it is about 1½ inches long60 days after fertilization: the fetus is about 4 inches long and eyes, eyelids, and nostrils can be identified3 months after fertilization:the fetus is about 10 inches long and fine hair is visible on the head145-150 days after fertilization:the lambs are born

Cytokinesis is the division of cytoplasm. Cytokinesis is distinguished from the prokaryotic process of binary fission.
