What is the cell membrane's role?
What is the cell membrane's role?
The cell membrane is a thin, flexible barrier that encloses the cell and controls what enters and leaves.
What is the role of ribosomes?
What is the role of ribosomes?
Ribosomes are responsible for protein synthesis. They read genetic information from messenger RNA (mRNA) and assemble amino acids into proteins.
What is Mitosis?
What is Mitosis?
Mitosis is a type of cell division that produces two identical daughter cells from a single parent cell. It's used for growth and repair.
