The Cell in Action

What is the difference between Passive and Active Transport?

• Passive transport requires energy; active transport does not.

• Passive transport moves particles from low to high concentration; active transport moves them from high to low.

• Passive transport moves particles from high to low concentration without energy; active transport moves them from low to high concentration with energy.

• Passive transport and active transport both require energy.

What are the 2 types of Passive Transport?

• Endocytosis and Exocytosis

• Osmosis and Diffusion

• Active Transport and Passive Transport

• Photosynthesis and Cellular Respiration

What is the difference between Osmosis and Diffusion?

• Osmosis involves the movement of particles from low to high concentration; diffusion involves water molecules.

• Osmosis is the movement of water molecules through the cell membrane; diffusion is the movement of particles from high to low concentration.

• Osmosis requires energy; diffusion does not.

• Osmosis and diffusion both require energy.

In which organelle does Photosynthesis occur?

• Mitochondria

• Nucleus

• Chloroplasts

• Ribosomes

Which process requires energy to move particles into the cell?

• Osmosis

• Diffusion

• Endocytosis

• Exocytosis

Which process requires energy to move particles out of the cell?

• Osmosis

• Diffusion

• Endocytosis

• Exocytosis

How do cells produce more cells?

• By photosynthesis

• By going through the cell cycle

• By cellular respiration

• By fermentation

Does Mitosis occur in Eukaryotic cells or Prokaryotic cells?

• Prokaryotic cells

• Eukaryotic cells

• Both

• Neither

What are homologous chromosomes?

• Identical chromosome copies

• Coiled structure of DNA

• Similar chromosomes

• Chromosomes with different genes

What is the centromere?

• Identical chromosome copies

• The region that holds chromatids together

• Coiled structure of DNA

• Simple cell division
