Understanding Phloem Tissue in Plants

What is the primary function of phloem tissue in plants?

• To store nutrients

• To provide structural support

• To transport organic compounds like sugars

• To transport water from roots to leaves

Which component of phloem is primarily responsible for transporting sugars?

• Phloem parenchyma

• Phloem fibers

• Companion cells

• Sieve tube elements

What role do companion cells play in the phloem tissue?

• They support the metabolic activities of sieve tube elements

• They transport water

• They store starch and other substances

• They provide structural support

How do phloem fibers contribute to the phloem tissue?

• By transporting sugars

• By storing nutrients

• By participating in photosynthesis

• By enhancing stability and resisting mechanical stress

What mechanism is involved in the translocation of sugars in plants?

• Active transport

• Osmosis

• Pressure flow mechanism

• Diffusion
