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

1. What is the cell theory?
Ans. The cell theory is a fundamental concept in biology that states that all living organisms are composed of cells, cells are the basic unit of structure and function in living organisms, and new cells arise from pre-existing cells. This theory was proposed by Matthias Schleiden and Theodor Schwann in the 19th century and has since been widely accepted.
2. What is the function of the plasma membrane?
Ans. The plasma membrane, also known as the cell membrane, is a thin, flexible barrier that surrounds the cell. Its main function is to regulate the movement of substances into and out of the cell, allowing nutrients to enter and waste products to exit. It also plays a role in cell signaling, cell adhesion, and maintaining the cell's shape.
3. What is the role of the Golgi apparatus in the cell?
Ans. The Golgi apparatus, also called the Golgi complex, is an organelle found in eukaryotic cells. Its main function is to process, modify, and package proteins and lipids synthesized in the endoplasmic reticulum. It consists of a series of flattened membrane sacs called cisternae. The Golgi apparatus also plays a role in sorting and directing newly synthesized molecules to their appropriate destinations within the cell.
4. What is the function of mitochondria in cells?
Ans. Mitochondria are often referred to as the powerhouses of the cell because their main function is to generate energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. They have their own DNA and are capable of producing their own proteins. Mitochondria are found in large numbers in cells that require a lot of energy, such as muscle cells.
5. What is the significance of chloroplasts in plant cells?
Ans. Chloroplasts are organelles found in plant cells and some protists that are responsible for photosynthesis. They contain a green pigment called chlorophyll, which captures light energy and converts it into chemical energy through a series of reactions. This energy is used to produce glucose and other organic compounds, which serve as a source of energy for the plant. Chloroplasts are unique to plant cells and are not found in animal cells.
