Exploring Plant Cell Structure

What is the primary function of the cell wall in plant cells?

• To facilitate photosynthesis in plant cells.

• To store nutrients and waste products.

• To regulate the movement of water in and out of the cell.

• To provide structural support and protection.

Name the organelle responsible for photosynthesis in plant cells.

• Chloroplasts

• Nucleus

• Ribosomes

• Mitochondria

What is the role of the vacuole in a plant cell?

• The vacuole stores substances and maintains turgor pressure in plant cells.

• The vacuole produces energy for the cell.

• The vacuole is responsible for photosynthesis.

• The vacuole transports nutrients throughout the plant.

Describe the function of chloroplasts in plant cells.

• Chloroplasts function to conduct photosynthesis in plant cells.

• Chloroplasts store water for the plant.

• Chloroplasts are responsible for cellular respiration.

• Chloroplasts help in the absorption of nutrients from the soil.

What is the difference between a plant cell and an animal cell?

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

• Plant cells are smaller than animal cells.

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

• Plant cells have a nucleus; animal cells do not.

Which structure in plant cells is responsible for maintaining turgor pressure?

• Vacuole

• Cell wall

• Chloroplast

• Mitochondria

What is the function of the endoplasmic reticulum in plant cells?

• The endoplasmic reticulum is responsible for photosynthesis in plant cells.

• The endoplasmic reticulum transports water in plant cells.

• The endoplasmic reticulum synthesizes proteins and lipids in plant cells.

• The endoplasmic reticulum stores nutrients in plant cells.

How do plasmodesmata contribute to cell communication in plants?

• Plasmodesmata allow direct communication and transport of substances between plant cells.

• Plasmodesmata prevent communication between plant cells.

• Plasmodesmata are involved in photosynthesis only.

• Plasmodesmata are structures that store nutrients in plant cells.

What is the significance of the central vacuole in plant cells?

• The central vacuole helps in the movement of nutrients between cells.

• The central vacuole is primarily responsible for photosynthesis.

• The central vacuole is significant for storage, maintaining turgor pressure, and supporting cell growth in plant cells.

• The central vacuole is involved in protein synthesis.

Identify the main components of the plant cell membrane and their functions.

• Nucleic acids, which store genetic information

• Cellulose, which provides energy storage

• The main components of the plant cell membrane are phospholipids, proteins, carbohydrates, and cholesterol.

• Lipids, which are only found in animal cells
