Short Answer Questions
- What is the primary function of the mitochondria?
Answer: The primary function of the mitochondria is to generate energy for the cell through cellular respiration.
- Describe the structure and function of the endoplasmic reticulum (ER).
Answer: The ER is a membranous organelle composed of two types: rough ER (RER) and smooth ER (SER). The RER is involved in protein synthesis, while the SER is involved in lipid synthesis.
- What is the role of the lysosome in cellular biology?
Answer: The lysosome is a membrane-bound organelle responsible for cellular digestion and waste removal.
