Notebook drawing, not to scale
a rounded cell with letters A, B and C. A sits on the thin boundary line around the cell. B sits on the jelly-like fill between the other parts. C sits on a large round body near the middle. Job column: A | controls what goes in and out of the cell; B | the jelly-like region where the other parts sit and many reactions happen; C | holds the DNA and directs the cell's activities.
Ari's job column says part B is the jelly-like region where the other parts sit and many reactions happen. What is part B called?
- Ribosomes
- Cell wall
- Cytoplasm
- Mitochondria
Notebook drawing, not to scale
a rounded cell with letters A, B and C. A sits on the thin boundary line around the cell. B sits on a large round body near the middle. C sits on a small bean-shaped part with a folded inside. No job column.
Bo sketches a cell and circles part C. What job does part C do for the cell?
- Controls what goes in and out of the whole cell
- Releases energy from food for the cell to use
- Makes energy for the cell to use
- Makes proteins for the cell
No job column. Jun studies a bean leaf cell and circles part C. What job does part C do for the cell?
- Supports the cell and gives it shape
- Makes food and energy for the cell
- Holds the DNA and directs the cell's activities
- Stores extra water and keeps the cell firm and full
“not to scale” Kira fills in a job column for a bean leaf cell. Which job belongs in the blank row for part D?
- Stores extra water and keeps the cell firm and full
- Makes proteins for the cell
- Makes sugar using light energy
- Releases energy from food for the cell to use
Bean leaf cell drawing, not to scale
a boxy cell with letters A and B. A sits on the thin boundary line just inside a thick outer layer. B sits on that thick outer layer. Job column: A | controls what goes in and out of the cell.
Luz reads a job column: part A controls what goes in and out of a bean leaf cell. What is part A called?
- Nucleus
- Cell membrane
- Cell wall
- Cytoplasm
Job cards, not to scale
a rounded cell with letters A, B and C. A sits on the thin boundary line around the cell. B sits on a small bean-shaped part with a folded inside. C sits on tiny dots in the jelly. Job column: A | controls what goes in and out of the cell; B | blank box; C | makes proteins.
Milo makes a job card for each part of a cell. Which job goes on the card for part B?
- Holds the DNA and directs the cell's activities
- Makes energy for the cell to use
- Releases energy from food for the cell to use
- Stores extra water and keeps the cell firm and full

Noah's class reads this sentence about a cell: one part releases energy from food for the cell to use. Which part is it?
- Nucleus
- Mitochondria
- Cell membrane
- Ribosomes
Pia circles part D on a cell drawing. What job does part D do for the cell?
- Makes proteins for the cell
- Controls what goes in and out of the whole cell
- Holds the DNA and directs the cell's activities
- Releases energy from food for the cell to use
Poster corner, not to scale
a boxy plant cell with letters A, B and C. A sits on a large open space in the middle. B sits on a thick outer layer around the whole cell. C sits on a green oval part with stacks inside. Job column: A | stores water and keeps the cell firm; B | supports and protects the cell and gives it shape.
Ren reads a class poster that lists a job for part A of a plant cell: it stores water and keeps the cell firm. What is part A called?
- Central vacuole
- Cytoplasm
- Chloroplasts
- Cell membrane
