Cell Basics
What is the smallest unit of life?
A Cell
I am the control center of the cell. What am I?
Nucleus
Which type of cell has a cell wall: plant or animal?
plant cell
What jelly-like material fills the cell and holds organelles?
Cytoplasm
True or False: All living things are made of more than one cell.
False
What is an organism made of only one cell called?
Unicellular
I control what enters and leaves the cell. What am I?
Cell membrane
What organelle uses sunlight to make food?
Chloroplast
What organelle stores water, food, and waste?
Vacuole
Is a bacterium prokaryotic or eukaryotic?
prokaryotic
What is an organism made of many cells called?
Multicellular
I make energy available for the cell. What am I?
Mitochondria
Which type of cell usually has one large central vacuole?
Plant cell
What structure gives plant cells extra support and protection?
Cell wall
A student compares a nucleus to a school principal. Why does this analogy work?
Both help direct or control activities.
Explain the difference between prokaryotic and eukaryotic cells.
Prokaryotic cells do not have a nucleus, while eukaryotic cells have a nucleus.
I make proteins for the cell. What am I?
Ribosomes
Name two structures plant cells have that animal cells do not.
Cell wall and chloroplasts
What organelle helps break down waste and worn-out cell parts?
Lysosome
A cell has a nucleus, cell membrane, and mitochondria but no cell wall or chloroplasts. What type of cell is it most likely?
Animal cell
What are the three main parts of cell theory?
All living things are made of cells, cells are the basic unit of life, and all cells come from existing cells.
I package and ship materials around the cell. What am I?
Golgi body
Why do plant cells need both chloroplasts and mitochondria?
Chloroplasts make sugar using sunlight, and mitochondria release usable energy from sugar.
What organelle network helps move and process materials such as proteins through the cell?
Endoplasmic reticulum (ER)
What would happen if a cell membrane stopped controlling what enters and leaves?
The cell could not maintain proper conditions and might die.
