NDD#5 Water Balance In Plants

What is the primary role of water in plants?

• It acts solely as a reactant in photosynthesis.

• It is used exclusively for structural support.

• It is only used for temperature regulation.

• It serves as a primary transport mechanism and is involved in chemical reactions.

Which process is water a product of in plants?

• Transpiration

• Respiration

• Osmosis

• Phototropism

What is the function of guard cells in plants?

• To facilitate photosynthesis

• To regulate water loss through stomata

• To store water

• To transport nutrients

What adaptation helps plants reduce water loss from their leaves?

• Increasing the number of stomata

• Thickening of the cuticle

• Decreasing the number of chloroplasts

• Thinning of the cuticle

What is a characteristic of sclerophyll leaves?

• They are very soft and water-rich.

• They are thin and easily breakable.

• They are hard and crisp to reduce water loss.

• They are large and flat for maximum water absorption.

How do succulents like cacti adapt to their environment?

• By having thin, permeable skin

• By growing large leaves

• By increasing transpiration

• By storing water in their stems

What is the role of fine hairs on some plants?

• To capture prey

• To attract pollinators

• To reduce water loss

• To increase water absorption from the air

Why do deciduous plants lose their leaves in autumn?

• To prepare for photosynthesis in winter

• To attract pollinators for the next season

• To increase water absorption

• To recoup important chemicals like chlorophyll

What is the significance of sunken stomata in some plants?

• To help with temperature regulation

• To increase gas exchange

• To capture more sunlight

• To store more water

How does reducing the surface area of leaves affect a plant?

• Increases the rate of photosynthesis

• Reduces water loss but may also reduce photosynthesis

• Promotes faster growth

• Enhances gas exchange
