What cell part helps distribute chromosomes to new cells during cell division?
Describe the structure and function of a centrosome. It’s a non membranous structure composed of 2 rodlike centrioles. It helps distribute chromosomes to new cells during cell division.
What distributes chromosomes to new cells?
The are cellular organlles consisting of two centrioles. During mitosis they distribute chromosomes to new cells. … When two centrioles are found next to each other, they are usually at right angles. During division, you may also see groups of threads attached to the centrioles.
What is the name of the structures responsible for generating the spindle fibers?
Spindle fibers are produced in the centrosome from cylindrical microtubules called centrioles.
What is Golgi apparatus function?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.
What does a centrosome look like?
Centrosomes are made up of two, barrel-shaped clusters of microtubules called “centrioles” and a complex of proteins that help additional microtubules to form. This complex is also known as the microtubule-organizing center (MTOC), since it helps organize the spindle fibers during mitosis.
How do dividing cells distribute chromosomes to daughter cells?
Mitotic Cell Division: the division of the nucleus into two nuclei. (Brooker, 306) Divides one cell nucleus into two nuclei, distributing the duplicated chromosomes so that each daughter cell will receive the same complement of chromosomes. … (Brooker Online, C15 Animation) Also referred to as ‘mitosis.
When a cell divides by meiosis it produces new cells which have?
During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
What is the interphase of a cell?
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
What is the phase where chromatin condenses to form chromosomes?
During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.
What does the mitotic spindle control?
The mitotic spindle accurately segregates genetic instructions by moving chromosomes to spindle poles (anaphase A) and separating the poles (anaphase B) so that, in general, the chromosomes and poles are positioned near the centers of the nascent daughter cell products of each cell division.
