Transport : Transport in Plants
What do you know about transport in plants? : What do you know about transport in plants? What substances does the plant need for photosynthesis?
How does it get to the leaves?
How do materials get to the storage organs from the points of manufacture?
How does plant food/fertilizer get into the plant and move through the plant?
Materials transported in Plants : Materials transported in Plants Water and Minerals
Transported from roots to the living cells throughout the plant.
Needed especially by cells which are metabolically active such as
Growing points
Developing flowers and fruits
Cells carrying out photosynthesis
Most of the water leaves the plant in TRANSPIRATION as part of its transport mechanism
Materials transported in Plants : Materials transported in Plants Manufactured materials
e.g. sucrose, amino acids (produced after photosynthesis) are transported in soluble form
They are moved from points of production or storage to other areas of the plant which need them
For e.g. growing points
Materials transported in Plants : Materials transported in Plants Waste materials
These materials are moved from where they are produced to old leaves, stems and bark which will eventually fall off.
Some waste material are transported to storage areas
Materials transported in Plants : Materials transported in Plants Plant growth substances
Growth substances like auxins are transported by diffusion from growing points where they are made to the areas behind the tips where they regulate the elongation of cells.
