Organelle Function

What is the function of chloroplasts?

• They are responsible for cellular respiration.

• They are responsible for photosynthesis, converting sunlight into chemical energy.

• They store genetic information.

• They help in the synthesis of proteins.

What is the role of centrioles in cell division?

• Centrioles help organize the mitotic spindle during cell division, ensuring proper chromosome separation.

• Centrioles are responsible for DNA replication during cell division.

• Centrioles assist in the formation of the nuclear envelope during cell division.

• Centrioles play a role in the synthesis of ribosomes during cell division.

What organelle is known as the 'clean up crew' of the cell?

• Mitochondria

• Ribosome

• Lysosome

• Endoplasmic Reticulum

What is the difference between smooth and rough endoplasmic reticulum?

• The rough ER has ribosomes and is involved in protein synthesis, while the smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.

• The rough ER is involved in lipid synthesis, while the smooth ER is involved in protein synthesis.

• Both the rough and smooth ER are involved in protein synthesis only.

• The rough ER is found only in plant cells, while the smooth ER is found only in animal cells.

What is the role of the nucleolus?

• Producing ribosomal RNA (rRNA) and assembling ribosomes.

• Synthesizing proteins for the cell.

• Storing genetic information.

• Regulating cell division.

What is the function of ribosomes?

• They are responsible for DNA replication.

• They are the sites of protein synthesis, translating messenger RNA into polypeptide chains.

• They help in the transport of nutrients across the cell membrane.

• They are involved in the breakdown of waste materials in the cell.

What provides structural support to plant cells?

• The cell membrane

• The cytoplasm

• The cell wall

• The nucleus

What is the function of cytoplasm?

• Cytoplasm is the jelly-like substance that fills the cell, providing a medium for chemical reactions and supporting organelles.

• Cytoplasm is responsible for the synthesis of proteins within the cell.

• Cytoplasm acts as a barrier to protect the cell from external damage.

• Cytoplasm is involved in the storage of genetic material.

What is the function of peroxisomes?

• To synthesize proteins

• To detoxify harmful substances and break down fatty acids

• To store genetic information

• To produce energy through cellular respiration

What is the role of the cell membrane?

• It provides energy to the cell.

• It regulates what enters and exits the cell, providing protection and support.

• It stores genetic information.

• It synthesizes proteins.
