asters are formed only in plant cells during its cell division true of false
Answers
Answer:
false
Explanation:
An aster is a cellular structure shaped like a star, consisting of a centrosome and its associated microtubules during the early stages of mitosis in an animal cell. Asters do not form during mitosis in plants.
False
An aster is a cellular structure shaped like a star, consisting of a centrosome and its associated microtubules during the early stages of mitosis in an animal cell. Asters do not form during mitosis in plants. This allows the cell to divide properly with each daughter cell containing full replicas of chromosomes
An aster is a star-shaped cellular structure formed around each centrosome during mitosis or meiosis in an animal cell. They are considered part of the cytoskeleton. Astral rays are made of microtubules which are the largest of the three main cytoskeleton components (microfilaments, intermediate filaments and microtubules) and radiate from the centrosphere. Before asters are formed, centrosomes are formed. These are also cytoskeleton structures consisting of two bundles of microtubules called centrioles which are stuck to each other at a right angle and normally stay near the cell's nuclear envelope. Right before mitosis or meiosis begins, the centrosome divides into two daughter centrosomes, and each centrosome migrates to the opposite side of the nucleus. As mitosis or meiosis begins, centrosomes create two new structures:
