Question

All eukaryotic cells have a cytoskeleton, including plant cells, which have cell walls as well. What does the cytoskeleton in a plant cell do that the cell wall cannot?

Answer 1

It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing.
It helps keep the organelles in place and directs their movement as needed.
It keeps the DNA safely enclosed in the nucleus and holds the nucleus together.
It provides anchoring places for the cell cytoplasm and helps it move molecules.

Answer 2

The cytoskeleton is a network of microfilaments, intermediate filaments, and microtubules. The cytoskeleton functions to:

1) give shape to cells lacking a cell wall;

2) allow for cell movement, eg, the crawling movement of white blood cells and amoebas or the contraction of muscle cells;

3) movement of organelles within the cell and endocytosis;

4) cell division, ie, the movement of chromosomes during mitosis and meiosis and the constriction of animal cells during cytokinesis.

Answer 3

The cytoskeleton maintains cell shape and protects it

Answer 4

think of cytoskeleton as the frames or scaffoldings inside a cell.
I would seriously think of the functions of each organelle in a cell if I were you. These things aren't just for memorization.
