Why might plant cells not need centrioles for mitosis or meiosis?
Wiki User
∙ 11y ago
The centriole's function is currently unknown and because of this, it is considered to be useless. Plants don't have centrioles, and it functions just fine as a plant. Centrioles are probably unnecessary in animals as well.

∙ 10y agoIn animal cells, centrioles function as microtubule organizing systems that aid in separating duplicated genetic material in preparation for cell division. They are formed from centrosomes. On the other hand, plant cells do not have a need for centrioles because their centrosomes duplicate during interface and thus are capable of producing microtubule spindles to control the separation of genetic material themselves.

I don't know why higher plants don't have them.
Centrioles form astral rays during nulear division and formation of astral rays is not required in plant cells, therefore, centrioles are absent.

A cell's nucleus divides to form two identical nuclei during the stage of the cell cycle known as?
For body cells: mitosis For sex cells: meiosis
Centrioles might be observed in some of these cells with an electron microscope In which cells would these be observed and what is the function of these cell organelles?
because centrioles have a dagree and can use a electron microscope to see the nucleaus inside
For what reasons might a cell use mitosis?
To Heal Injuries by reproducing itself (Cell division).
What are uses of meiosis?
Meiosis is used to make gametes in the human body. The gametes will either be sperm or eggs depending on the gender.
Were you able to observe any of these organelles in these Cells?
what organelles are you referring to? Plants and animal cells each have a few organelles that the other one doesn't. for instant, plant cells have cell wall, but animal cells don't. and animal cells have centrioles but plant cells don't....
Which happens first mitosis or cell division?
Mitosis was first discovered and meiosis evolved out of mitosis. Mitosis stands for the first division of a cell into two genetic identically cells. Meiosis stands for two divisions into four genetic different cells.

During mitosis one cell divides into how many new daughter cells?
umm i think it is 2 but it might be 4 i get miosis and meiosis mixed up somtimes but i am pritty sur it is 2

For what reasons might a cell use meiosis?
All human cells have 46 chromosomes, 23 pairs. In sexual reproduction, if an egg and a sperm each with 46 chromosomes joined then the zygote would have 92 chromosomes. To keep this from happening, cells undergo meiosis. In meiosis the cells replicate the chromosomes and divide then divide again so they end up with only 23 chromosomes. Cells with half the number of chromosomes are called gametes.
How fast do human cells do mitosis?
very fast ................... ask your boi teacher not the world because .................. you might get someone like me that dosent know

When you are born do you have billions of cells?
yes you are made of billions of cells You always have to have have billions of cells, or you will have a genetic meltdown. So yes, you do (but before you're born you're still undergoing mitosis, so you might have a little less than a billion).
How might gametes production in male bees differ from normal meiosis?
They do not go through meiosis.
What is a cell called that gets stuck in mitosis and continuously divides?
I might not understand your question correctly but here is a possible answer.. A cell can get stuck in mitosis through various reasons. one of them is through inhibition of cyclin dependent kinases or perhaps due to unsatisfied spindle pole checkpoints. The cells that get stuck in mitosis this way will simply not progress further and will not divide. A big chance is that a lot of these cells will go into apoptosis when stuck in this phase for too long. you could check if your cells are stuck in mitosis by measuring the DNA contents with a FACS machine, an increased population with n=2 (or higher) probably reflects a defect in the dividing stage of the cells.
