Question

The term Eumitosis is used for
A:- Mitosis is higher plants.
B:- Mitosis in animals.
C:- Mitosis where the spindle is extranuclear.
D:- Mitosis in the intranuclear spindle.

Answer 1

In cell biology, cell division could be a part of the cell cycle, during which, replicated chromosomes are separated into two new nuclei. The cellular division offers rise to genetically identical cells in which the whole variety of chromosomes is maintained.

Complete answer:
Eumitosis is a form of mitosis wherein the nuclear membrane dissolves at some point of prometaphase in order that there stays no difference between cytoplasm and nucleoplasm. The chromosomes stay connected to the spindles via their centromeres.
• Mitosis in Higher plants- Life goes through an open division wherein the nuclear envelope (NE) breaks right all the way down to permit the mitotic spindle to connect to the chromosomes, exposing the genetic cloth to the cytoplasm.
• Mitosis in animals- Mitosis is a cell division that takes place in animal cells in which the cell divides into 2 daughter cells. The quantity of chromosomes withinside the mom cell is equal to that during every ensuing daughter cell.
• Mitosis where the spindle is extranuclear- If the mitotic spindle forms in the nucleus, it’s far intranuclear mitosis, while if the spindle bureaucracy outside the nucleus, it’s far stated to be extranuclear mitosis.
• Mitosis in intranuclear spindle- Fungal mitotic divisions are intranuclear: in this ‘closed mitosis’ the department spindle forms in the nucleus. This is pretty special from the ‘open mitosis’ visible in maximum animals and plant life in which the nuclear envelope disassembles and microtubules invade the nuclear area to shape the department spindle.
Whereas, the appropriate option is (C)-Mitosis where spindle is extranuclear.

Note: During mitosis, the body’s, that have already duplicated, condense and connect to spindle fibers that pull one copy of every chromosome to opposite sides of the cell. When the spindle fibers formed outside the nuclear, it is called open mitosis or eumitosis.
