FAQs on Cheat Sheet : Cell - The Unit of Life - Biology Class 11 - NEET

1. What is the basic structure of a cell?
Ans. The basic structure of a cell includes the cell membrane, cytoplasm, and nucleus. The cell membrane is a protective barrier that controls the movement of substances in and out of the cell. The cytoplasm is a jelly-like substance that contains organelles, which are specialized structures that perform various functions. The nucleus houses the cell's genetic material (DNA) and regulates cellular activities.
2. What are the differences between prokaryotic and eukaryotic cells?
Ans. Prokaryotic cells are generally smaller and simpler than eukaryotic cells. They lack a nucleus and membrane-bound organelles, and their genetic material is found in a single circular chromosome. Eukaryotic cells, on the other hand, have a defined nucleus that contains their DNA, and they possess various organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which carry out specific functions within the cell.
3. What is the role of the cell membrane in cellular function?
Ans. The cell membrane plays a crucial role in maintaining homeostasis within the cell. It acts as a selective barrier, allowing certain substances to enter or leave the cell while keeping others out. The membrane is composed of a phospholipid bilayer with embedded proteins that facilitate transport and communication between the cell and its environment.
4. How do cells obtain energy?
Ans. Cells obtain energy primarily through the process of cellular respiration, which converts glucose and oxygen into ATP (adenosine triphosphate). In eukaryotic cells, this process occurs in the mitochondria, where glucose is broken down in the presence of oxygen to release energy. Additionally, some cells can generate energy through anaerobic processes when oxygen is not available.
5. What are organelles and their functions?
Ans. Organelles are specialized structures within a cell that perform specific functions vital for the cell's survival and operation. For example, mitochondria are responsible for energy production, ribosomes synthesize proteins, the endoplasmic reticulum aids in the processing and transport of proteins and lipids, and lysosomes break down waste materials and cellular debris. Each organelle plays a unique role in maintaining cellular health and function.
