- 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.A few layers of thick walled parenchymatous cells, which lie below the endodermis in dicot root is called Conjuctive tissue Pericycle Casparian strips Hypodermis3. Ground Tissue *comprises the rest of the plant that is not dermal or vascular *used for photosynthesis, storage, and support *the specific type of ground tissue depends on its location Root & Stem: (internal to vascular tissue) (external to vascular tissue) Leaves: mesophyll (elongated, columnar) mesophyll (irregular shaped, spaced apart)
