Eukaryotic cells topic 1.2

Question 1

Organelles are compartmentalized structures that serve specific purposes, eg:

Answer 1

• 80S ribosomes – Responsible for protein synthesis (translation)
• Nucleus – Stores genetic information (site of transcription)
• Mitochondria – Site of aerobic respiration (ATP production)
• Endoplasmic reticulum – Transports materials between organelles
• Golgi complex – Sorts, stores, modifies & exports secretory products
• Centrosomes – Involved in cell division (mitosis and meiosis)

Question 2

Key distinctions of Animal cells from plant cells

Answer 2

1. No chloroplasts
2. No cell wall
3. No plasmodesmata
4. Temporary vacuoles
5. Cholesterol present in the cell membrane
6. Glucose -> glycogen

Question 3

Key distinctions of Plant cells from animal cells

Answer 3

1. Have chloroplasts
2. Cell wall (cellulose)
3. Plasmodesmata
4. Large central vacuole
5. No cholesterol in the cell membrane
6. Glucose -> starch
