Real Cells as Building Blocks practice questions
Which statement about plant cells is correct?
Plant cells are always larger than the whole plant
Plant cells have a rigid, fixed shape ✓
Plant cells cannot be seen under a microscope
Plant cells can easily change shape like animal cells
Plant cells keep a fixed, rigid shape, which is different from most animal cells.
Which statement about animal cells is correct?
Animal cells can be seen easily without a microscope
Animal cells generally do not have a fixed, rigid shape ✓
Animal cells always have a rigid, fixed shape
Animal cells are not part of any living thing
Unlike plant cells, animal cells generally do not keep one fixed, rigid shape.
What is one key difference between plant cells and animal cells at a simple level?
Plant cells can be seen without a microscope while animal cells cannot
Plant cells have a fixed shape while animal cells often do not ✓
Plant cells do not exist in real plants
Plant cells are never alive while animal cells are always alive
A simple difference is that plant cells keep a rigid, fixed shape, while animal cells can vary more in shape.
Why do scientists use microscopes to study cells?
Because cells are too colourful to see normally
Because cells only exist at night
Because cells move too fast to be seen
Because cells are too small to be seen clearly with the naked eye ✓
Cells are far too tiny to be seen in detail without the magnifying power of a microscope.
