Animal Cells

1. What is an Animal Cell?

Answer: 

Animal cell is a basic unit of life in animals. It lacks a cell wall but is surrounded by a plasma membrane. Organelles like the nucleus, mitochondria, and endoplasmic reticulum, which perform functions like producing energy, and help in protein synthesis are present.

2. State the various types of animal cells..

Answer:

The various type of animal cell are:

• Blood Cells
• Nerve cells
• Skin Cells
• Muscle Cells
• Fat Cells

3. What is the role of lysosomes?

Answer:

Lysosomes are spherical organelles enclosed by a membrane. It contains enzymes that aid in breaking down cellular waste, debris, and foreign materials through a process called hydrolysis. This helps maintain cellular cleanliness and recycles useful components.

4. What is the size of an animal cell?

Answer:

Animal cells generally have diameters ranging from 10 to 30 micrometers. However, this size can vary based on cell type and function. Like nerve cells can extend to over a meter in length, while red blood cells are usually around 7 micrometers in diameter.

5. Who invented animal cell?

Answer:

Robert Hook discovered the animal cell in 1665. Theodor Schwann and Matthias Schleiden gave the cell theory, which states that cells are the basic units of life in both plants and animals. It help us understanding the animal cell in detail.

Animal cell forms the basic structural and functional unit of organisms. Unlike plant cells, it lacks a cell wall and chloroplasts but consists of various membrane-bound organelles like the nucleus, Golgi apparatus, mitochondria, etc. In animal cells, these organelles function together to perform essential cellular processes like energy production, immune response, protein synthesis, and cellular communication.
