• Prokaryotes only have chloroplasts

• Prokaryotes don't have a nucleus

• Eukaryotes are more simple organisms

From the following, choose which reason does not support the statement: cell membranes are semipermeable.

• They help maintain homeostasis

• They help obtain nutrients

• It helps the cell make DNA

• It helps the cell maintain equilibrium with the environment

The mitochondria is the "powerhouse" of the cell because it makes:

• Protein

• ATP

• DNA

Define cell membrane

• The control center of a cell

• Selectively permeable, lets things in and out of cells

• The site of photosynthesis and cellular respiration

• The liquid portion of the cell

Nucleus

• Contains genetic information

• Specialized structure that carries out a specific function

• creates proteins

• converts glucose to ATP

Define diffusion

• Movement of water

• Movement of molecules from low to high concentration

• Concentration gradient

• Movement of molecules from high to low concentration

If we had a higher concentration of outside of the cell than inside the cell, which direction would water move?

• Into the cell

• Out of the cell

• Remain the same
