FAQs on Cell- The Unit of Life Practice Questions - DPP for NEET

1. What is the function of a cell in living organisms?
Ans. Cells are the basic building blocks of life and have various functions. They provide structure and support, carry out biochemical reactions, store genetic information, and help in the transportation of materials within an organism.
2. What are the different types of cells found in living organisms?
Ans. There are two main types of cells: prokaryotic and eukaryotic cells. Prokaryotic cells, found in bacteria, lack a nucleus and membrane-bound organelles. Eukaryotic cells, found in plants, animals, and fungi, have a nucleus and various organelles.
3. How does a cell maintain its internal environment?
Ans. Cells maintain their internal environment through a process called homeostasis. They regulate the concentration of molecules and ions, control pH levels, and regulate temperature to ensure that the cell functions optimally.
4. What is the role of the cell membrane?
Ans. The cell membrane is a selectively permeable barrier that surrounds the cell. It regulates the movement of substances in and out of the cell, maintains the cell's shape, and protects the cell from its external environment.
5. How do cells communicate with each other?
Ans. Cells communicate with each other through various mechanisms, such as chemical signals and direct physical contact. They release signaling molecules, such as hormones, which bind to specific receptors on target cells and trigger a response. Cells can also communicate through gap junctions, which allow direct exchange of ions and small molecules between adjacent cells.
