What is the basic unit of life?

• organism

• atom

• molecule

• cell

What is the function of the cell membrane?

• Regulates what enters and leaves the cell

• Helps in cell division

• Stores genetic information

• Provides energy for the cell

What organelle is responsible for producing energy in the cell?

• nucleus

• ribosomes

• mitochondria

• endoplasmic reticulum

What is the function of the nucleus in a cell?

• Regulates the movement of substances in and out of the cell

• Control center and stores genetic material (DNA)

• Produces energy for the cell

• Provides structural support for the cell

What are the differences between plant and animal cells?

• Presence of cell membrane, chloroplasts, and small central vacuole in animal cells

• Absence of cell wall, chloroplasts, and large central vacuole in plant cells

• Presence of cell wall, chloroplasts, and large central vacuole in plant cells

• Presence of cell wall, mitochondria, and small central vacuole in plant cells

What is the function of the endoplasmic reticulum?

• Cell division and replication

• Waste elimination

• Energy production and storage

• Protein and lipid synthesis, and material transportation

What is the role of ribosomes in a cell?

• Energy production

• Waste elimination

• Cell division

• Protein synthesis

What is the function of the Golgi apparatus?

• Regulating cell division

• Packaging and processing proteins and lipids

• Storing genetic information

• Producing energy for the cell

What are the differences between prokaryotic and eukaryotic cells?

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

• Prokaryotic cells are larger in size compared to eukaryotic cells.

• Prokaryotic cells and eukaryotic cells are the same and have no differences.

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack a nucleus and membrane-bound organelles.

Green plants produce their own food through the process of photosynthesis.

• All living things use energy
• All living things contain cells
• All living things maintain homeostasis
• All living things grow
