701. Which one of the following is called the ‘digestive bag’ in the cell?

1. Golgi body
2. Mitochondrion
3. Ribosome
4. Lysosome

Option “4” is correct
Lysosomes are called the digestive bags and also suicide bags. This is because they contain enzymes that help the cell to digest the food eaten by the organism.
702. Which one of the following is also called the ‘power house’ of the cell?

1. Golgi body
2. Mitochondrion
3. Ribosome
4. Lysosome

Option “2” is correct
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the power houses of the cell.
703. Food is stored in plants in the form which carbohydrate?
