How do plants get their energy?

• through a reaction called chlorophyll 
• by a process called photosynthesis 
• by absorbing mineral nutrients from soil 
• by eating other organisms 

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

• all of the above

Absorption of water in plants take place by

• osmosis

• diffusion

• both (a) and (b)

• none of the above

Ascent of sap in plants takes place through

• Cortex

• Epidermis

• Xylem

• Phloem
