• All cells come from pre-existing cells.

  Which invention was the most important thing that helped scientists develop the cell theory?

• compound light microscope

• petri dish

• scanning electron microscope

• dissection tools

Sac within the cytoplasm that STORES fluid, plants have a larger one that stores food and water.

• vacuole

• lysosome

• cell wall

• ribosome

Is the jelly-like substance in the cell that contains the organelles

• ribosome

• cytoplasm

• cell wall

• chloroplast

This structure is only found in plants and prokaryotes (Gives it a rigid shape)

• cell wall

• cytoplasm

• centriole

• nucleus

The control center of the cell that HAS DNA

• cytoplasm

• ribosomes

• lysosomes

• nucleus

The outer part of the cell that is in both plants and animal cells.

"The fence"

• cell membrane

• cell wall

• nucleus

• cytoplasm

This organelle make PROTEINS for the cell
