Respiration
D
Photosynthesis
Verified step by step guidance1
Understand that roots uptake nutrients primarily through a process called active transport, which involves the movement of ions and molecules against their concentration gradient using energy, typically in the form of ATP.
Recognize that active transport is necessary because the concentration of nutrients in the soil is often lower than inside the root cells, requiring energy to move these nutrients into the cells.
Differentiate active transport from other processes like transpiration, which is the movement of water through a plant and its evaporation from aerial parts, and respiration, which is the process of breaking down sugar to release energy.
Acknowledge that photosynthesis is unrelated to nutrient uptake in roots, as it is the process by which plants convert light energy into chemical energy in the form of glucose, occurring in the chloroplasts of leaf cells.
Conclude that active transport is the correct process for nutrient uptake in roots, as it specifically involves the energy-dependent movement of nutrients into the plant cells.
