Know dnt do this,
The leaves are the engines of the plant. They are adapted to bring together the raw materials, water, carbon dioxide and light to produce energy for the plant in the form of sugars (glucose) through photosynthesis. These sugars will then be transported from the leaves to use elsewhere in the plant.
The leaf does this in three basic stages:
1. Collecting light - The leaf uses pigments in the form of chlorophyll cells to capture the light energy.
2. Light dependent phase - The effect of light on the chlorophyll cell causes a flow of electrons which splits the water into hydrogen ions and oxygen.
3. Production of sugars - The hydrogen ions are used in the reduction of carbon dioxide to produce sugars (glucose)
Transpiration.
This is evaporation of water from the plant. This evaporation happens through tiny pores on the leaf surface called stomata and helps create a pressure gradient to draw new water up from the roots into the xylem, where nutrients (minerals) can be carried up the plant in the transpiration stream until they get to where they are needed. Here, they can diffuse or be transported into the cells where they are required. Evaporation (transpiration) helps keep the movement of water going up the plant, creating our main transport system, the transpiration stream.
Nutrient uptake and transport.
All plants need certain minerals which we call nutrients . We put them in a bottle and when mixed with water we have a nutrient solution which can be used to feed our plants. The nutrient solution can be absorbed through the leaves as a foliar spray but is more commonly applied to the roots and absorbed through the root hair cells through diffusion, osmosis and through proteins that span the root membrane.
Once into the plant via the root hairs, the water and nutrient molecules will move through and around root cells until the nutrients enter the xylem where the transpiration stream will transport them to where they are needed.
The nutrients and water are used at their destination to make more complex molecules and help perform normal metabolic functions. Water again reaches the leaves where it transpires from the plant and also goes to play it's part in photosynthesis, and the whole process starts all over again
