Biology S1: Mid-Unit 3 - Part 1

Which statement is part of the cell theory?

• Cells are independent structures.

• Cells are able to make new organisms.

• All cells are the same.

• All cells are produced from other cells.

Where does most of the metabolic activity in the cell occur?

• Nucelus

• DNA

• Cytoplasm

• Cell Wall

• Organ Systems

• Organs

NGSS.HS-LS1-2

Which structure would not be found in a prokaryotic cell?

• Membrane-Bound Organelles

• DNA

• Cytoplasm

• Cell Membrane

Which statement is true of both active transport and facilitated diffusion?

• Both require ATP.

• Both move materials down a concentration gradient.

• Both involve proteins in the cell membrane.

• Both occur in only one direction.

Which phrase best defines diffusion?

• movement of particles from a region of low concentration to a region of high concentration

• movement of particles from a region of high concentration to a region of low concentration

• movement through a cell membrane using energy from ATP

• active transport of particles up a concentration gradient

Which process does osmosis involve?

• movement of solute up a concentration gradient

• movement of solute across the cell membrane

• movement of water across a cell membrane

• movement of water up a concentration gradient

Which term names the process whereby molecules in vesicles are exported out of the cell?

• Diffusion

• Osmosis

• Exocytosis

• Endocytosis

In a eukaryotic cell, where is most of the DNA located?

• Nucleus

• Cytoplasm

• Cell Wall

• Golgi Body

The inner membrane of mitochondria consists of many folds.

What is the purpose of this membrane?

• provide structural support for the mitochondria

• decrease the surface area so substances can’t diffuse in

• increase the surface area to allow more space for ATP synthesis

• house enzymes needed for digestion
