What is the cytoskeleton?
Q: What is the cytoskeleton?
A: The cytoskeleton is a scaffolding present in all cells made of protein.
Q: What are the functions of the cytoskeleton?
A: The cytoskeleton keeps cell shape, protects the cell, enables cells to move, helps transport inside the cytoplasm and in cell division.
Q: Who introduced the concept and term "cytosquelette"?
A: French embryologist Paul Wintrebert introduced the concept and term "cytosquelette" in 1931.
Q: How many main kinds of cytoskeletal filaments are present in eukaryote cells?
A: Eukaryote cells contain three main kinds of cytoskeletal filaments which are microfilaments (actin filaments), intermediate filaments, and microtubules.
Q: What do cytoskeletal elements interact closely with in cells?
A: Cytoskeletal elements interact closely with the cell membrane and the endoplasmic reticulum.
Q: What role does the cytoskeleton play in transporting inside the cytoplasm?
A: The cytoskeleton helps in the movement of vesicles and organelles inside the cytoplasm.
Q: What is the primary function of the cytoskeleton in cell division?
A: The cytoskeleton plays a role in cell division.
