Biology

The cytoskeleton is important because

• It gives the cell its shape

• It strengthens the cells

• It helps the cells move and divide

• All of the above

The following features are found only in the plant cell

• Lysosome

• Cell wall

• Chloroplast

• Central vacuole

The following is found inside the nucleus

• Cytoplasm

• DNA

• Mitochondria

• Nucleolus

The nucleus is the

• Power house of the cell

• Waste collector in the cell

• Control center of the cell

• protein factory in the cell

Centrosome and centrioles play a major role in

• Cell movement

• Cell division

• Cell contraction

• Cell membrane

It provides the cell with energy

• Vesicle

• Nucleus

• mitochondria

• Vacuole

Directs all cell activities "Brain or Control Center of cell"

• Lysosomes
• Nucleus
• ribosomes
• Mitochondria

Jelly-like substance found inside cell that acts as a medium for chemical reactions within the cell

• Nuclear Membrane
• Golgi Body
• Cytoplasm
• Ribosome

"powerhouse of the cell" breaks down sugar molecules to release energy, site of cellular respiration, double membrane, self-replicating, contains own DNA, cristae

• Mitochondria
• Chloroplast
• Cell Wall
• Vesicle
