Plant Water Movement and Root Functions

The video tutorial provides an overview of plant organs and their functions, focusing on roots, stems, and leaves. It explains the roles of different plant tissues, including dermal, vascular, and ground tissues. The structure and function of roots are detailed, highlighting tap and fibrous roots. The video also covers water and nutrient transport mechanisms, emphasizing osmosis and root pressure. Finally, it explains the process of transpiration and the forces driving water movement in plants.

What is the primary function of the root in plants?

• To anchor the plant and absorb water and nutrients

• To transport nutrients and water

• To produce food through photosynthesis

• To facilitate gas exchange

Which plant tissue is responsible for protecting the outer surface of the plant?

• Ground tissue

• Vascular tissue

• Meristematic tissue

• Dermal tissue

What is the main role of the xylem in plants?

• To transport glucose

• To protect the plant

• To store nutrients

• To carry water and minerals

Which type of root system is primarily found in monocots?

• Taproot system

• Fibrous root system

• Adventitious root system

• Aerial root system

What is the function of root hairs?

• To increase surface area for absorption

• To transport water

• To protect the root

• To store nutrients

What is the role of the endodermis in roots?

• To produce glucose

• To control water and nutrient entry into the vascular system

• To facilitate gas exchange

• To store water

How does water move from the soil into the root?

• Through active transport

• Through capillary action

• By osmosis following ion transport

• Via diffusion

What creates the negative pressure that helps pull water up through the plant?
