Exploring Plant and Animal Cells

What is the function of the cell membrane?

(a)  

• The cell membrane generates energy for the cell.

• The cell membrane stores genetic information.

• The cell membrane controls the passage of substanc
• The cell membrane is responsible for protein synthesis.

Identify the structure that provides support in plant cells.

• Cell wall

• Cell membrane

• Chloroplast

• Cytoplasm

Compare the presence of chloroplasts in plant and animal cells.

• Chloroplasts are found in both plant and animal cells.

• Chloroplasts are present in all eukaryotic cells including fungi.

• Animal cells contain chloroplasts but plant cells do not.

• Chloroplasts are present in plant cells but absent in animal cells.

Label the nucleus in a diagram of a cell.

• Nucleus

• Cytoplasm

• Mitochondria

• Cell membrane

What is the role of mitochondria in a cell?

• Mitochondria store genetic information for the cell.

• Mitochondria are responsible for protein synthesis.

• Mitochondria produce energy (ATP) for the cell.

• Mitochondria regulate cell division and growth.

Differentiate between prokaryotic and eukaryotic cells.

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

• Eukaryotic cells are always unicellular; prokaryotic cells are multicellular.

• Prokaryotic cells have a nucleus; eukaryotic cells do not.

• Prokaryotic cells contain membrane-bound organelles; eukaryotic cells do not.

Describe the process of photosynthesis in plant cells.

• Photosynthesis is the process by which plants convert light energy, water, and carbon dioxide into glucose and oxygen.

• Photosynthesis is the process of plants breathing in oxygen and releasing carbon dioxide.

• Plants absorb nutrients from the soil and convert them into sunlight.

• Photosynthesis occurs only at night using stored energy.

What structure is responsible for protein synthesis?

• Ribosome

• Golgi apparatus

• Nucleus

• Mitochondria

Identify one key difference between plant and animal cells.

• Animal cells have a cell wall; plant cells do not.

• Plant cells have lysosomes; animal cells do not.

• Animal cells can photosynthesize; plant cells cannot.

• Plant cells have a cell wall; animal cells do not.

Explain the function of the vacuole in plant cells.

• The vacuole is responsible for photosynthesis in plant cells.

• The vacuole acts as a barrier against pathogens in plant cells.

• The vacuole generates energy for the cell through respiration.

• The vacuole stores substances, maintains turgor pressure, and supports cell growth in plant cells.
