Plant Survival! Quiz By M. Ibrahim Khan 15371

What is transpiration?

• Transpiration is the process of water movement through a plant and its evaporation from aerial parts, primarily from the leaves.

• Transpiration is the movement of water from the soil to the roots.

• Transpiration refers to the absorption of nutrients by plant roots.

• Transpiration is the process of photosynthesis in plants.

What do stomata allow to enter the plant?

• Oxygen

• Nutrients

• Carbon dioxide

• Water

What is the main function of xylem?

• The main function of xylem is to transport water and minerals.

• To facilitate photosynthesis in leaves.

• To provide structural support to the plant.

• To store food for the plant.

Can stomata close? Why is this important?

• Stomata only close at night for photosynthesis.

• Closing stomata increases water loss.

• Yes, stomata can close, and this is important for conserving water and regulating gas exchange.

• Stomata cannot close under any circumstances.

What do phloem tissues transport?

• Carbon dioxide

• Water and minerals

• Sugars and other organic nutrients

• Oxygen and nitrogen

In which direction does xylem carry water?

• Downward, from leaves to roots

• Horizontally, between branches

• Upward, from roots to leaves

• Inward, from the atmosphere to the roots

How does transpiration benefit a plant?

• Transpiration benefits a plant by facilitating water and nutrient uptake, cooling the plant, and maintaining turgor pressure.

• Transpiration helps plants absorb carbon dioxide for photosynthesis.

• Transpiration prevents plants from losing water during drought.

• Transpiration increases soil nutrient levels directly.

What happens to water absorbed by the roots?

• Water absorbed by the roots is transported through the plant for various functions and may be lost through transpiration.

• Water is only used for photosynthesis.

• Water is converted into glucose immediately.

• Water is stored in the roots indefinitely.

Why is carbon dioxide important for plants?

• Plants do not require carbon dioxide for photosynthesis.

• Carbon dioxide is important for plants because it is a key ingredient in photosynthesis, enabling them to produce energy and oxygen.

• Carbon dioxide is harmful to plants and inhibits their growth.

• Carbon dioxide is primarily used by animals for respiration.

How do phloem and xylem work together in a plant?

• Phloem and xylem are both responsible for photosynthesis in plants.

• Phloem absorbs sunlight while xylem stores carbon dioxide.

• Phloem transports nutrients and sugars, while xylem transports water and minerals, working together to support plant growth.

• Phloem transports water and minerals, while xylem transports nutrients and sugars.
