Transport System in Plants: Transpiration and Translocation

The video explores plant transport systems, focusing on transpiration and translocation. It covers the roles of root hair cells, phloem, xylem, and guard cells in transporting water, minerals, and sugars. The video explains how these components work together to support plant functions like photosynthesis and growth.

What is the primary function of the plant organ system consisting of roots, stems, and leaves?

• To produce flowers

• To absorb sunlight

• To transport substances like water, food, and minerals

• To protect the plant from pests

How do root hair cells increase their efficiency in absorbing water?

• By reducing the number of mitochondria

• By increasing their surface area

• By having a thick cell wall

• By having a small vacuole

What is the main role of phloem tissue in plants?

• To store nutrients

• To transport water from roots to leaves

• To provide structural support

• To transport dissolved sugars

In which direction can sucrose move through the phloem tissue?

• Only downwards

• Both upwards and downwards

• Only upwards

• It does not move

What is the primary function of xylem tissue?

• To store energy

• To transport water and mineral ions

• To produce seeds

• To transport dissolved sugars

What is the transpiration stream?

• The process of photosynthesis

• The movement of sugars through the phloem

• The loss of water from the plant

• The movement of water from roots to leaves

What role do guard cells play in plants?

• They transport water

• They control the opening and closing of stomata

• They store nutrients

• They produce chlorophyll
