At the stage of cytokinesis during mitosis, plant cells develop cell plates, while animal cells form cleavage furrows. The cell plate is formed by vesicles that fuse at the center of the dividing cell, eventually leading to the formation of a new cell wall that separates the two daughter cells. In contrast, cleavage furrows pinch the cell membrane inward to divide the cytoplasm in animal cells. This distinction is crucial for the successful division of cells in these two types of organisms.
What else can I help you with?
The cytoplasm divides during which process?
The cytoplasm divides during the process of cytokinesis, which follows the division of the nucleus in mitosis or meiosis. Cytokinesis ensures that each daughter cell receives a portion of the cytoplasm along with the replicated chromosomes.
What stage does the cleavage appear in mitosis?
There are five stages of mitosis starting with prophase and ending with telophase. The cleavage furrow develops during cytokinesis which is after the telophase, so the cleavage furrow does not develop in mitosis at all.
What immediately happens after zygote form?
After a zygote forms through fertilization, it undergoes cell division through a process called cleavage. This gives rise to a multicellular structure called a blastocyst. The blastocyst will then implant into the uterine lining, where it will continue to develop into an embryo.
Among coelomates which of these develops by spiral cleavage and the mouth forms before the anus?
Annelids, such as earthworms, are coelomates that develop by spiral cleavage and have a mouth that forms before the anus during embryonic development.
What does a living cell always develop from?
A living cell always develops from a pre-existing cell through a process called cell division. This process involves the replication of genetic material and the division of the cell's cytoplasm, leading to two daughter cells that are genetically identical to the original cell. This principle is a fundamental concept in biology, encapsulated in the idea that all cells arise from other cells.
The cytoplasm divides during which process?
The cytoplasm divides during the process of cytokinesis, which follows the division of the nucleus in mitosis or meiosis. Cytokinesis ensures that each daughter cell receives a portion of the cytoplasm along with the replicated chromosomes.

There are five stages of mitosis starting with prophase and ending with telophase. The cleavage furrow develops during cytokinesis which is after the telophase, so the cleavage furrow does not develop in mitosis at all.
What are the six stages of animal development?
The six stages of animal development are fertilization, cleavage, gastrulation, organogenesis, growth, and adulthood. Fertilization occurs when the sperm and egg fuse to form a zygote, which then undergoes cell division during cleavage. Gastrulation involves cell movements that form the three germ layers, leading to organogenesis where organs begin to develop. Finally, growth occurs as the organism matures into adulthood.
What immediately happens after zygote form?
After a zygote forms through fertilization, it undergoes cell division through a process called cleavage. This gives rise to a multicellular structure called a blastocyst. The blastocyst will then implant into the uterine lining, where it will continue to develop into an embryo.
Among coelomates which of these develops by spiral cleavage and the mouth forms before the anus?
Annelids, such as earthworms, are coelomates that develop by spiral cleavage and have a mouth that forms before the anus during embryonic development.
What happens to the polar bodies formed during oogenesis?
During oogenesis, polar bodies are formed as a result of unequal division of cytoplasm during meiosis. These polar bodies do not have the ability to develop into a mature egg cell and eventually disintegrate or are reabsorbed by the body.
What is the difference between the crystal faces and cleavage faces?
cleavage surface are smooth and shiny as the fracture is due to weakness in the bonds between the atoms rather than a breakage. Crystal face is where the crystal development such as twinning take place.
What is the pattern of cleavage in amphibians?
In amphibians, the pattern of cleavage is typically holoblastic and unequal. This means that the entire egg undergoes cleavage, but the divisions are not equal; the animal pole (where the embryo will develop) divides more rapidly than the vegetal pole. The resulting cells, or blastomeres, vary in size, with smaller cells forming at the top and larger ones at the bottom. This unequal cleavage contributes to the organization and differentiation of the developing embryo.
Methds of paragraph development using division?
In division, you develop a topic by breaking it down into smaller parts.
How does one cell become many cells?
One cell can become many cells through a process called cell division, where a single parent cell divides into two or more daughter cells. This process allows organisms to grow, develop, and replace damaged or old cells. Cell division typically involves two main stages: interphase, where the cell prepares for division, and mitosis or meiosis, where the division of the genetic material and cytoplasm occurs.
Why is cell division important for a baby?
Cell Division is important for a baby because the child needs to grow and develop.
At what phase does a spindle develop during cell division?
A spindle develops during the metaphase stage of cell division.
