21. Why do plant cells need cell walls?

22. What organelle would control the wilting of a plant? Explain.

Answer :

Final answer:

Cells are enclosed by a membrane, with the nucleus being the largest visible organelle. The endoplasmic reticulum is involved in protein production, while the Golgi apparatus processes and delivers proteins. The mitochondria supplies energy to the cell. Plant cells have a cell wall, chloroplasts carry out photosynthesis, and a vacuole stores materials. Ribosomes are involved in protein synthesis, and lysosomes contain digestive enzymes. Prokaryotic cells lack a nucleus and organelles, while eukaryotic cells have them. Plant cells need cell walls for support and protection. The central vacuole controls wilting in plants.
