Transport in Plants

B7.1

​*non-woody dicotyledonous plants

Multiple Choice

Where is xylem found in the plant?

• leave -> roots -> stem

• roots -> stem -> leaves

• root hairs -> leaves -> veins

• stem -> roots

Multiple Choice

Which of these is true?

• Xylem vessels carry water and dissolved minerals up the plant
• Phloem tissue carry water and dissolved minerals up the plant
• Xylem vessels carry dissolved sucrose up and down the plant

Multiple Choice

Plant transports food made in the leaves to __________. 

• roots 
• stem
• flowers 
• all of the above

Multiple Choice

Vascular tissue that transports water and minerals UPWARDS from a plant's roots is know as ______.

• Chlorophyll
• Phloem
• Stomata
• Xylem

Multiple Choice

The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.

• Phloem
• Stomata
• Chlorophyll
• Xylem

Multiple Choice

Plant absorbs water through the _________. 

• stem
• roots 
• leaves 
• all of the above

Multiple Choice

What is the name of the part of the root that allows water and minerals enter?

• root hairs
• epidermis
• phloem
• phyla

Multiple Choice

This is the definition for which word: The movement of particles down a concentration gradient (from a high concentration to a low concentration)

• Osmosis
• Diffusion
• Active transport
• Transpiration

Multiple Choice

How do water enter the roots from the soil?

• diffusion
• osmosis
• transpiration
• active transport

Multiple Choice

what is the function of root hair?

• it is place to store the food
• it has large surface area to absorb more water

Transpiration

loss of water vapour from plant leaves by evaporation of water at the surfaces of the mesophyll cells followed by diffusion of water vapour through the stomata

Multiple Choice

Transpiration is

• the movement of water through a plant from the roots up the stem
• the loss of water from the leaves of a plant by the process of evaporation
• the flow of water into plant roots by osmosis from the soil
• the process of minerals and sugars moving through plant veins

Multiple Choice

Water vapour exits a plant leaf by

• the stomata
• the epidermis
• the palisade cells
• the spongy mesophyll

Multiple Choice

What happens to the transpiration rate as light intensity increases?

• It increases
• It stays the same
• It decreases

Multiple Choice

What happens to the movement of air bubble if apparatus is kept in front of a fan

• Air bubble does not move

• Air bubble moves very little

• Air bubble does not change its position

• Air bubble moves very fast

Multiple Choice

Adaptation to reduce transpiration

• Broader leaves

• Stunted growth

• More stomata

• Narrow leaves

Multiple Choice

Why is the evaporation of water from leaves important?

• It cools leaves and helps move water up the plant.
• It makes the plant wilt
• It helps the plant to respire
