through a series of metabolic reactions and electrons transferring energy to different forms in redox reactions
Irish potato
23. Explain the process by which plants get water from the soil into the leaves?
rain
node
the root hairs on the root tips absorb water into the soil through osmosis. this water travels up the roots - up the stems - and to the leaves throughout the plant by capillary action. once absored in leaves - the water leaves the plant through trans
