Explain the importance of active transport in ion uptake by root hair cells
Explain the importance of active transport in ion uptake by root hair cells
1 AnswerQuestions and Answers
1 AnswerDescribe active transport as the movement of molecules or ions into or out of a cell through the cell membrane, from a region of their lower concentration to a region of their higher concentration (i.e. against a concentration gradient), using energy released during respiration

1 AnswerInvestigate the factors that influence diffusion, limited to: surface area, temperature, concentration gradient and distance
Investigate the factors that influence diffusion, limited to: surface area, temperature, concentration gradient and distance
1 AnswerUnderstand diffusion as the net movement of molecules or ions from a region of their higher concentration to a region of their lower concentration (i.e. down a concentration gradient), as a result of their random movement
