CCEA Osmosis and Plant Transport

Osmosis only concerns the movement of particles of

• salt
• water
• sugar
• solute

A potometer is used to

• measure photosynthesis
• measure water uptake
• find the rate of diffusion from a plant
• measure respiration

If plant cells become plasmolysed the plant will 

• die instantly
• stand upright
• become turgid
• wilt

Of all the water taken in by a plant, only a little is needed for

• supporting the plant

• respiration

• photosynthesis

• transporting minerals

In order for transpiration to take place water must

• diffuse and then evaporate
• evaporate and then undergo osmosis
• evaporate and then diffuse
• evaporate through the stomata

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

Which of the following is NOT a way in which plants use water?

• Transport
• Support
• Energy
• Photosynthesis

The evaporation of water from leaf tissue is mostly from

• spongy mesophyll 
• epidermis
• waxy layer
• stomata

Water vapour moves out of the plant leaf by the process of

• osmosis
• evaporation
• active transport
• diffusion

Water vapour exits a plant leaf by

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