Which cell structure serves as a cell's boundary from its environment?
The Cell Membrane, and also the cell wall in the case of a bacteria or plant cell.In Animal cells, it is the Cell Membrane. It may also be referred to as the Plasma Membrane.I Plant cells, it is the cell wall.
What is it important for the nuclear memebrane to distintegrate in mitosis?
The breakdown of the nuclear membrane during mitosis allows for the separation of replicated chromosomes into two daughter cells. This ensures proper distribution of genetic material and accurate cell division. It also allows for the formation of the mitotic spindle, which helps in segregating the chromosomes.
What is the difference in plant cells and animal cells?
Plant cells have cell walls made of cellulose, chloroplasts for photosynthesis, and large central vacuoles. Animal cells do not have cell walls, chloroplasts, or large central vacuoles, but may have specialized structures like cilia or flagella for movement.
What is the name for the fibers that become visible during metaphase?
The strands are called chromatids. Druing prophase, the chromosomes coil and shorten and the nuclear memebrane dissolves. Each chromosome is made up of a pair of strands called chromatids, which are connected by a spindle of fibers called a centromere.
Do centrioles organize the mitotic spindle in cell division?
No they do not, centrioles are the only organelles in a cell which are not synthesised during the G1 phase. During the telophase of cell division the two pairs of centrioles in each of their own centrosomes break down. Whilst a new nuclear memebrane is forming around the chromosomes a new par of centrioles is synthesised. Therefore centrioles are made during the telophase of the mitotic phase. Centrioles then divide into two pairs during the Synthesis phase. Each pair of centrioles then move to opposite poles of the nucleus during prophase.
What does the cell memebrane do for the plant cell?
It is the mussle of the cell. In the mussle cell there is more of it
How does chloroplast work on a plant cell?
it help the cell memebrane
What is a rigid structure surrounding the cell memebrane?
cell wall
Is the cell memebrane selectively permeable?
Yes.
What is a cell memebrane's job?
It helps control what enters and leaves the cell.
What type of cell have a cell membrane?
All cells have a cell memebrane. Prokaryotic and eukaryotic.
Do plant cells have a cell memebrane?
Yes,they have a membrane.It is inside cell wall.
How can one cell pass the cell membrane but the other can't?
because of its selectival memebrane
Do plant cell have a cell memebrane?
Yes, plants have both cell walls (outside) and cell membranes (inside).
What does the cell memebrane do in a animal cell?
Protects cell and controls what goes in and out through passive and active transport
What model is used to describe the cell memebrane?
kind of like the orange peel of an orange
What is a nuclear memebrane?
It is the double-layered membrane surrounding the nucleus of a eukaryotic cell, separating the nucleoplasm from the cytoplasm.
