Unit 3 Cells

You are looking at a cell under a microscope. It has free floating genetic material and is covered with flagella. It is most likely a..?

• Eukaryotic plant cell

• Eukaryotic animal cell

• Prokaryote

Which organelle destroys wastes from the cell?

• Golgi Apparatus

• Lysosome

• Vacuole

• Mitochondria

This organelle is studded with ribosomes!

• Nucleus

• Rough ER

• Cytoplasm

• Chloroplast

Osmosis is best defined as..

• The movement of water particles across a cell membrane

• The movement of any particle across a cell membrane

• The transfer of sodium across a cell membrane

• The transfer of oxygen across a cell membrane

A hypertonic solution is defined as...

• A solution with less solute than what is inside the cell

• A solution with more solute than what is inside the cell

• A solution with equal solute than what is inside the cell

Which organelle is exclusively in eukaryotic cells?

• Genetic material

• Cell Membrane

• Cell Wall

• Nucleus

A cell containing a high amount of solute is placed in a hypotonic solution. What would happen to this cell after being placed in the solution?

• It would shrink

• It would grow larger and/or burst

• It would remain the same

Water travels from high concentration to low concentration.

• True

• False

This active transport process removes wastes from a cell

• Exocytosis

• Endocytosis

• Concentration gradient

• Diffusion

If a cell has 20% solute, and the solution has 50% solute, this means that the cell is in what type of solution?

• Hypotonic

• Isotonic

• Hypertonic

• I don't know
