Choose the incorrect pair

• Ribosomes - Protein synthesis

• SER - Formation of lipid molecules

• Golgi apparatus - Synthesizing and packaging the substances

• Lysosomes - Storage of energy in the form of ATP

Answer explanation

Option 1 - Ribosomes present in endoplasmic reticulum are responsible for protein synthesis in the cell. Option 2 - Smooth endoplasmic reticulum (SER) is responsible for formation of lipids and fat molecules. Option 3 - Golgi apparatus synthesizes substances like proteins and lipids from endoplasmic reticulum via vesicles and stores, modifies and pack the material, and send them to different locations inside and outside the cell. Option 4 - Lysosomes are responsible for digestion of dead cells or any bacteria in the cell. Mitochondria is responsible for storage of energy in the form of ATP molecules. So correct answer is option 4.

Find the incorrect statement among the following.

• Cytoplasm is also called protoplasm

• Mitochondria stores energy which is used for various chemical activities and mechanical work.

• Lysosomes are formed by the golgi apparatus

• Nucleus, mitochondria and plastids have their own DNA.

Answer explanation

Option 1 is the incorrect statement. Nucleus and cytoplasm is collectively called protoplasm.
