What plant cell structure is analogous to animal cell's cleavage furrows?
In plant cells, instead of a cleavage furrow, a cell plate forms down the middle of the cell, separating it into two daughter cells. This process entails the delivery of Golgi-derived and endosomal vesicles carrying cell wall and cell membrane components to the plane of cell division and the subsequent fusion of these vesicles within this plane.After formation of an early tubulo-vesicular network at the center of the cell, the initially labile cell plate consolidates into a tubular network and eventually a fenestrated sheet. The cell plate grows outward from the center of the cell to the parental plasma membrane with which it will fuse, thus completing cell division. Formation and growth of the cell plate is dependent upon the phragmoplast, which is required for proper targeting of Golgi-derived vesicles to the cell plate.As the cell plate matures in the central part of the cell, the phragmoplast disassembles in this region and new elements are added on its outside. This process leads to a steady expansion of the phragmoplast, and concomitantly, to a continuous retargeting of Golgi-derived vesicles to the growing edge of the cell plate. Once the cell plate reaches and fuses with the plasma membrane the phragmoplast disappears.This event not only marks the separation of the two daughter cells, but also initiates a range of biochemical modifications that transform the callose-rich, flexible cell plate into a cellulose-rich, stiff primary cell wall.The heavy dependence of cell plate formation on active Golgi stacks explains why plant cells, unlike mammalian cells, do not disassemble their secretion machinery during cell division.
Are chromosomes a part of the plant cell?
Yes, chromosomes are part of plant cells. They are located in the nucleus of the plant cell and carry genetic information in the form of DNA. Chromosomes play a crucial role in cell division and inheritance of traits in plant cells.
What part of animal cell that the plant cell does not have?
One key organelle found in animal cells but not in plant cells is the centriole. Centrioles are involved in cell division and are composed of microtubules arranged in a specific pattern. Plant cells do not have centrioles but instead have structures called microtubule organizing centers that perform similar functions. This structural difference is one of the key distinctions between animal and plant cells.
How does mitosis in plants differ from mitosis in animals?
1. There are no centrioles in a plant cell whereas they are present in animal cells. 2. In cytokinesis, the final step of mitosis, a cell's cytoplasm separates in half with each half containing one nucleus. An animal cell membrane pinches in, creating a cleavage furrow until the mother cell is pinched in half. In plant cells, a new cell wall is constructed at what was the midline of the mother cell. 3. In plant cell during telophase, phragmoplast (acting myosin microtubules) forms in centre of cell where as in animal cell contractile ring forms approximately midway between the 2 nuclei of the dividing cell. 4. Plant cell has a cell wall & animal cell lacks it 5. In plant cell nuclear and cell division found in special regions called meristems where as in animal cell divides everywhere, all the time.
What part in a plant cell is strong and stiff?
The still part of a plant cell is called Cell Wall. This is the rigid outermost layer of a plant cell. It makes the cell stiff -providing the cell with mechanical support - and giving it protection. It is found just inside the cell wall and is made up of complex lipids (fats) and proteins.
Which part of plant cell has the highest cell division rating?
Not every plant cell can divide.Meristamatic tissue cells are capable of dividing.

Is centriole part of a plant cell?
no it is an animal cellThey are characteristic organelle for animals. They arrange spindle fibers in cell division
Are chromosomes a part of the plant cell?
Yes, chromosomes are part of plant cells. They are located in the nucleus of the plant cell and carry genetic information in the form of DNA. Chromosomes play a crucial role in cell division and inheritance of traits in plant cells.
Part of the cell which play a rule during cell division?
it is part of the animal cell which play a rule during cell division?
Is interphase considered part of cell division?
No, interphase is part of the cell cycle and so is cell division. They occur at differenttimes in the cell cycle.
Is the endoplasmic reticulum a part of a plant cell?
part of a plant cell
What cell organelles lack membranes as part of their structure?
Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
What part of a cell facilitates cell division?
cytoskeleton
Is a cell wall part of plant cell or animal cell?
a plant cell:)
What cell part makes up the greatest part of a plant cell?
The central vacuole in the plant cell.
what is stiff in a plant cell?
stiff part in a plant cell
