Question

Draw a well labelled diagram of animal cell and mention one function of the main call organells.

Answer 1

• Nucleus - It controls all the activities of a cell and acts like the brain of a cell.
• Mitochondria - The energy required for various cellular activities is released by mitochondria in the form of ATP (adenosine triphosphate) molecules. Thus, mitochondria are referred to as the power houses of the cell.
• Endoplasmic reticulum - It is the site where many important chemical reactions take place, including the synthesis of important proteins, lipids and many other materials. It functions as a packaging system.
• Lysosome - They contain digestive hydrolytic enzymes such as acid hydrolase. With the help of these enzymes, they are able to digest a variety of substances including worn out organelles, proteins, nucleic acids, lipids and carbohydrates.
• Golgi apparatus - It is involved in the transport of lipids in cells.
• Vacuole - They help in the removal of unwanted structural debris and maintaining the turgor pressure within cells.
