Answer 1

Fill-in-the-blanks (using the word bank)

- The nucleus stores DNA and directs cell activities.
- The cell wall provides structure and support in plant cells.
- The chloroplast is the site of photosynthesis in plant cells.
- The lysosome breaks down waste materials.
- The mitochondria produces energy for the cell.
- The cell membrane surrounds the cell and controls entry/exit.
- The cytoplasm is a jelly-like substance that holds organelles.
- The cell wall is found only in plant cells and provides rigidity.
- The nucleus is responsible for controlling cell processes.
- The lysosome helps digest worn-out cell parts.

Matching (corrected)

21. Nucleus — Stores DNA and directs cell activities (controls cell processes)
22. Lysosome — Breaks down waste / digests worn-out cell parts
23. Chloroplast — Photosynthesis
24. Mitochondria — Produces energy for the cell (ATP)
25. Cell membrane — Controls entry/exit of substances into/out of the cell
