Transpiration 13th

What is the primary function of the xylem in plants?

• To transport glucose

• To transport water and minerals

• To regulate transpiration

• To transport amino acids

What are the vascular bundles in plants?

• Groups of phloem cells

• Tubes that carry food to the roots

• Arrangements of xylem and phloem

• Cells that absorb water from the soil

What is transpiration in plants?

• The process of photosynthesis

• The movement of glucose through the phloem

• The evaporation of water from the plant’s aerial parts

• The absorption of minerals by root hairs

How does the transpiration pull work?

• By pushing water from the leaves down to the roots

• By generating negative pressure that draws water upwards

• By actively pumping water from the soil into the roots

• By opening and closing the stomata

Which cells in the plant regulate the opening and closing of the stomata?

• Phloem cells

• Guard cells

• Xylem cells

• Root hair cells

What role do root hairs play in water absorption?

• They store food for the plant

• They maximize surface area for water absorption

• They transport glucose from the leaves

• They produce lignin to strengthen the plant

What is the primary factor that influences the rate of transpiration?

• The size of the plant

• The age of the plant

• Environmental factors such as temperature and humidity

• The amount of glucose produced

What is the function of lignin in xylem cells?

• To transport food throughout the plant

• To strengthen and toughen the xylem cells

• To regulate water loss through stomata

• To produce glucose during photosynthesis

Why is the transpiration stream important for plants?

What will be explored in the next part of the video?

• The movement of glucose throughout the plant

• The process of photosynthesis

• The absorption of minerals by roots

• The factors influencing transpiration
