Where does mitosis occur in garlic?


Where does mitosis occur location?

Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Why are the cells in mitosis located near the tip of the root?

Many cells lose the capacity to divide as they mature or divide only rarely. … For example, as plant roots grow, cells near the tip of the root, in the apical meristem, divide rapidly to push the root through the soil. The root cap detects the pull of gravity and directs the rapid growth of cells near the tip.

What evidence do you have that mitosis occurred in the roots?

The evidence we found that mitosis was a continuous process was that many of the cells we observed in a small part of the onion root was that they were between stages meaning they never stopped and started, the process kept going.

What organs does mitosis occur in?

Some cells go through mitosis as the organism grows but will eventually reach a stage where they no longer go through mitosis. This occurs in cells making up the various organs (heart, spleen, pancreas, etc.) and tissues of the central nervous system.

Where is mitosis most common in the onion root?

The meristematic region in the root tip is the actively growing region and thus the mitotic index is high.

How cell divides in an onion?

Onion Root Mitosis

  1. 1) Interphase is considered the first and last stage of plant cell division. …
  2. 2) Prophase. …
  3. 3) Metaphase is the middle stage at which point all the chromosome pairs line up in the center of the cell along spindle fibers that pull to either side of the cell.
  4. 4) Anaphase. …
  5. 5) Telophase.
