- Describe how roots absorb positively charged mineral ions by the process of cation exchange.Tissues in a carrot root, make a simple sketch and label the tissues. The outermost covering of the cylinder( the skin of the carrot root) is made up of dermal tissue, particularly the periderm. Beneath the periderm is a layer called the cortex which is made up of parenchyma, a type of ground tissue. Underneath the cortex is vascular cylinder which contains the ploem(the outer layer of the cylinder) and the xylem (the central core of the cylinder, the lightly colored part). Between the ploem and the xylem where the vascular cambium is located (a layer that is only one cell thick) a lateral meristematic tissue. plsssss help me sketch this and label it, thank you.Describe how water and minerals move in xylem. Why is water and mineral movement in xylem unidirectional?
- Why can xylem transport water and minerals using deadcells, whereas phloem requires living cells?why is pressure higher in parts of the phloem Where sugar is being loaded than in parts were sugars been removed?Explain why the vascular cambium forms acontinuous sheath that runs from near the tips of thebranches to near the tips of the roots, whereas the corkcambium is discontinuous in both space and time.
