🎓 Quick Viva
1. What is the function of the nucleus?
The nucleus contains most nuclear DNA and helps regulate gene expression and cellular activities.
2. What is the function of mitochondria?
Mitochondria are major sites of aerobic cellular respiration and ATP production.
3. What do ribosomes do?
Ribosomes synthesize proteins.
4. What is the function of chloroplasts?
Chloroplasts carry out photosynthesis in photosynthetic plant cells.
5. Do animal cells have a cellulose cell wall?
No. Animal cells have a plasma membrane but do not possess a cellulose cell wall.
6. What does the Golgi apparatus do?
It modifies, sorts and packages proteins and lipids.
7. What does the cell membrane do?
It forms a selectively permeable boundary regulating movement between the cell and its environment.
8. Do all plant cells contain chloroplasts?
No. Chloroplasts occur mainly in photosynthetic plant cells. Many non-photosynthetic plant cells do not contain developed chloroplasts.
✅ Result
The virtual investigation demonstrates that plant and animal cells share many eukaryotic structures, including the nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus and plasma membrane. Plant cells additionally possess a cell wall, typically have a prominent central vacuole, and photosynthetic plant cells contain chloroplasts.
