Plant, Animal & Other Cell Types — Drills · Grade 7 Science
Chapter: Cells, Transport & Cellular EnergyWhat these drills covers
By the end of Plant, Animal & Other Cell Types you should be able to:
- I can explain plant, animal & other cell types.
- I can use evidence, a model, and stated assumptions to support a biological explanation.
4 questions, multiple choice and written answer, each with a worked explanation.
Vocabulary used: cell wall, chloroplast, vacuole, turgor, specialized cell.
Problem 1
Which statement is accurate?
- Every root cell photosynthesizes
- Plant cells can respire
- Fungi are animals because they lack chloroplasts
- Walls replace membranes
Answer and explanation
Plant cells can respire
Plant cells release usable energy through respiration; a wall does not replace selective membrane exchange.
Problem 2
Why might a leaf cell and root cell have different visible structures?
Answer and explanation
Their functions differ. Many leaf cells photosynthesize and contain chloroplasts; many root cells obtain and transport materials without photosynthesis.
Problem 3
What shared energy process occurs in both plant and animal cells?
Answer and explanation
Both can carry out cellular respiration; plant photosynthesis does not replace it.
Problem 4
Does absence of chloroplasts prove a root cell is an animal cell?
Answer and explanation
No. Many plant cells are not photosynthetic; other structures and tissue context help identify them.
