What are the stages of mitosis in Whitefish?
Mitosis consists of 4 major stages: Prophase, Metaphase, Anaphase, and Telophase.
What stage of mitosis is indicated in the Whitefish blastula slide?
prophase stage
Cell Division – Mitosis – in Whitefish Blastula Cells The arrows (A) in the photo point to a cell in the prophase stage of mitosis. During this stage the chromosomes become visible, the nucleoli disappear, the nuclear membrane is broken down and the spindle begins to take form.
Why is the Whitefish blastula used for viewing mitosis?
To study mitosis, biologists often look at particular cells. Two specimens are commonly used by biologists to study mitosis: the blastula of a whitefish and the root tip of an onion. The whitefish embryo is a good place to look at mitosis because these cells are rapidly dividing as the fish embryo is growing.
What is Whitefish blastula?
Whitefish blastula is the early stage of embryo development of whitefish. The blastula is formed after an egg is fertilized and divides numerous times…
What do Whitefish blastula cells and Allium root tip cells have in common which make them good for illustrating mitosis?
O Both Whitefish Blastula and Allium Root Tip cells have multiple nuclei and therefore we can see all stages of Mitosis in one cell. They are not actively dividing because the organism is no longer growing.
What are the four stages of mitosis?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What stage of mitosis are most cells in?
prophase
Question 2: Based on the data provided, the longest stage of mitosis is prophase, which we can see because a majority of the cells are found in prophase.
What is a Whitefish blastula?
Why is the whitefish used to study mitosis quizlet?
Explain why whitefish blastula and onion root tip are selected for the study of mitosis. These plants are selected because whitefish blastula and onion root tip have cells that rapidly divide, making it easier to see the different stags of mitosis under a microscope.
How does mitosis differ between the onion root cells and the Whitefish blastula cells?
For mitosis experiments, onion root tips are used. The root tip cells are actively dividing meristematic cells and mitosis can be observed in them very easily. Whitefish blastula cells are used for studying mitosis. These cells are constantly dividing cells just like meristematic cells of plants.
