Side-by-side cell diagram, not to scale. Cell 1 is boxy; Cell 2 is rounded. Matching parts carry the same letter in both cells: Cell 1 has letters A, B, C, D, E, F and G; Cell 2 has letters B, C, D and G. No part names are printed on the drawing. Word bank: cell wall, cell membrane, cytoplasm, nucleus, mitochondrion, chloroplast, large central vacuole.
Ari labels a drawing of two cells. Part B is the outer edge of Cell 2 and sits just inside part A in Cell 1. Which part is B?
- Cytoplasm
- Large central vacuole
- Cell membrane
- Cell wall
Bo labels a drawing of two cells. Part D appears in both Cell 1 and Cell 2. Which word from the bank could D be?
- Large central vacuole
- Mitochondrion
- Cell wall
- Chloroplast
Esme labels a drawing of two cells. Part A is the outermost layer of Cell 1, and Cell 2 has no part A. Which part is A?
- Cell wall
- Nucleus
- Mitochondrion
- Cell membrane
Two cell drawings, not to scale, with each part named. Cell 1 is rounded. Cell 2 is boxy. Jun looks at two cell drawings. Which cell is the plant cell, and what shows it?
- Cell 1, because its outer edge is a cell wall
- Cell 2, because it has a cell wall and chloroplasts
- Cell 2, because it has no cell membrane
- Cell 1, because it is rounder and smaller
Two cell drawings, not to scale, with each part named. Cell 1 is boxy; no chloroplasts. Cell 2 is rounded. Kira looks at two cell drawings. Which cell is the plant cell, and what shows it?
- Cell 2, because Cell 1 has no chloroplasts
- Cell 1, because it has a cell wall and a large central vacuole
- Cell 1, because it has a wall instead of a membrane
- Cell 2, because its outer edge is a cell wall
Milo fills in a parts chart. What belongs in the box marked “?”
- No: the cell wall leaves no room for them
- Yes: plant cells have mitochondria too
- Yes: but they switch on when the leaf is in the dark
- No: chloroplasts do that job in plant cells
Noah fills in a parts chart. What belongs in the box marked “?”
- No: the cell wall takes the membrane’s place
- No: plant cells have no mitochondria or membrane
- Yes: the membrane sits just inside the cell wall
- Yes: but it sits outside the cell wall
Pia fills in a parts chart. What belongs in the box marked “?”
- Yes: the membrane counts as its cell wall
- Yes: animal cells have a stiff wall too
- No: animal cells have a membrane but no cell wall
- No: and plant cells have a wall instead of a membrane
Cell theory card
(1) All living things are made of one or more cells. (2) The cell is the basic living unit. (3) New cells come only from cells that already exist.
Tala reads about cell theory. Where do new cells come from?
- From cells that already exist, which divide
- From nonliving matter, such as soil
- From the food a living thing eats
- From nowhere: a living thing keeps the same cells as it grows
Zee reads about cell theory. Which of these is made of cells?
- A drop of rainwater
- A plastic leaf
- A smooth river rock
- A blade of grass
