Which of these are functions of cytoplasm?

• suspending cell organelles.

• acting as a barrier between the cell and the environment

• creating and using energy in the cell

• pushing against the plasma membrane to help the cell keep its shape.

• providing a site for many of the biochemical reactions of the cell.

The eukaryotic cytoskeleton is made up of a network of long, thin lipid fibers and has many functions.

• true

• false

Which of these are functions of the cytoskeleton?

• It helps to maintain cell shape.

• It provides a place for chemical reactions to occur.

• It plays important roles in both the intracellular movement of substances and in cell division.

• It holds organelles in place, and for some cells, it enables cell movement.

• It creates new proteins, lipids, and other organic molecules

Which of these are cytoskeleton fibers?

• microtubules

• intermediate filaments

• microfilaments

• cytoplasm

• microflagella

Cytosol is a watery, gel-like material that makes up much of the cytoplasm.

• true

• false

These are hollow cylinders and are the thickest of the cytoskeleton structures and most commonly made of filaments which are polymers of tubulin.

• microtubles

• intermeadiate filaments

• microfilaments

• cytoplasm

These are made of two thin actin chains that are twisted around one another. They are found in almost every cell, and are numerous in muscle cells and in cells that move by changing shape

• microtubles

• intermeadiate filaments

• microfilaments

• cytoplasm

These organize the inside structure of the cell by holding organelles and providing strength. They are also structural components of the nuclear envelope. Some are made of the protein keratin are found in skin, hair, and nails cells.

• microtubles

• intermeadiate filaments

• microfilaments

• cytoplasm
