1. What is the structure of a cell?
Ans. The structure of a cell refers to the various components that make up a cell, including the cell membrane, cytoplasm, nucleus, and organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
2. What is the function of the cell membrane?
Ans. The cell membrane, also known as the plasma membrane, acts as a protective barrier for the cell. It regulates the movement of substances in and out of the cell, maintains the cell's shape, and plays a role in cell signaling and communication.
3. What is the role of the nucleus in a cell?
Ans. The nucleus is often referred to as the control center of the cell. It contains the cell's genetic material, DNA, which directs the cell's activities and controls the synthesis of proteins. The nucleus also plays a role in cell division.
4. What are organelles?
Ans. Organelles are specialized structures within a cell that perform specific functions. Examples of organelles include mitochondria, which produce energy for the cell, and the endoplasmic reticulum, which is involved in protein synthesis and lipid metabolism.
5. How does the endoplasmic reticulum contribute to cell function?
Ans. The endoplasmic reticulum (ER) is a network of membranes that plays a crucial role in protein synthesis and lipid metabolism. It is involved in the production, folding, and transport of proteins within the cell. The ER also helps detoxify harmful substances and regulates calcium levels in the cell.
