Parts of a Cell
Level 1
Level 1
Holds the DNA inside a membrane
nucleus
What is the difference between unicellular organisms and multicellular organisms?
Unicellular organisms have only one cell. Multicellular organisms have more than one cell.
What is a producer?
An organism that uses the sun's energy to make food.
Produces and transports proteins and other molecules
Endoplasmic reticulum (ER)
Manufactures most of the cell's ATP
mitochondrion
What are the two types of cells?
prokaryote and eukaryote
An organism that eats another organism to get energy.
Builds proteins
ribosome
Boundary of the cell
cell membrane
What is a tissue?
A group of similar cells that work together
What is a cell's energy molecule called?
ATP
Contains enzymes for breaking down cellular waste
lysosome
A jelly-like substance that surrounds organelles
cytosol (cytoplasm)
What is the difference between passive and active transport?
Passive transport is when osmosis and diffusion happen without the cell doing any work. Active transport is when the cell uses energy (protein pumps) to perform diffusion.
Describe photosynthesis.
A process that uses energy from the sun to turn carbon dioxide and water into glucose.
Which cell structure is failing if an algal cell cannot distribute proteins throughout the cell?
Golgi apparatus
Modifies and packages proteins into vesicles
Golgi apparatus
What is Cell Theory?
All living things are made of cells, all cells come from preexisting cells, and cells perform the functions of living things.
What is the difference between anaerobic and aerobic respiration?
Anaerobic processing does not use oxygen; aerobic respiration uses oxygen.
Which cell structure is failing if a bacterial cell dries up?
capsule
