FAQs on Overview: Cell Structure Video Lecture - Biology for Grade 12

1. What is the basic structure of a cell?

Ans. The basic structure of a cell consists of a cell membrane, cytoplasm, and a nucleus. The cell membrane acts as a protective barrier, allowing certain substances to enter and exit the cell. The cytoplasm is a gel-like substance that fills the cell and contains various organelles. The nucleus is the control center of the cell, containing the genetic material and regulating cell activities.

2. How are plant cells different from animal cells in terms of structure?

Ans. Plant cells differ from animal cells in several ways. One major difference is the presence of a cell wall in plant cells, which provides rigidity and support to the cell. Animal cells do not have a cell wall. Additionally, plant cells contain chloroplasts, which are responsible for photosynthesis and give plants their green color. Animal cells do not have chloroplasts.

3. What are the different types of organelles found in a cell and their functions?

Ans. There are several types of organelles found in a cell, each with its specific function. The nucleus contains the cell's genetic material and controls cell activities. The mitochondria are responsible for producing energy through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism. The Golgi apparatus modifies, sorts, and packages proteins for transport. Lysosomes contain enzymes that break down waste materials. The vacuoles store water, nutrients, and waste products. The cytoskeleton provides structural support and helps with cell movement.

4. How do cells maintain their internal environment?

Ans. Cells maintain their internal environment through a process called homeostasis. They regulate the concentration of substances such as ions, nutrients, and waste products through the cell membrane. This is done through active transport, passive transport, and facilitated diffusion. Cells also regulate their internal pH, temperature, and water balance to ensure optimal functioning.

5. What is the significance of cell structure in relation to cellular functions?

Ans. The cell structure plays a crucial role in determining cellular functions. Each organelle within the cell has a specific function that contributes to overall cell activity. For example, the mitochondria are responsible for energy production, which is essential for cell metabolism. The nucleus contains the genetic material that controls cell growth and reproduction. The cell membrane regulates the passage of substances in and out of the cell, allowing for communication and maintaining homeostasis. Without the specific structures and functions of each organelle, cells would not be able to carry out their necessary functions for survival.
