What are the three main parts of hair?
Three major parts of hair are Cuticle, Cortex, and Medulla.
What is the function of passage cells in the endodermis of root?
In endodermis the passage cells passes the water molecules from the cortex to the protoxylem. Passage cells prevent the re entry of water molecules into the cortex.
What two structures does water and minerals pass through to get to xylem?
they pass through the root hairs to the cortex
Why the rate of water movement in an intact shoot is less than that measured in the potometer?
there is resistance to water movement across root cortex.
What is the outer covering of the root?
The Cortex
What encloses the cortex of a root?
The cortex (of hair root) is the middle layer of the epithelial cells- dermis and epidermis.
What are the main parts of roots?
root hair, epidermis, epiblem, cortex, endodermis, pericycle and lastly the vascular tissue in the centre of a root to transport the water
What are the different parts of the inner plant root?
cortex,epidermis,phloem,root hair,vascular cylinder, and the xylem
What are the three main parts of hair?
Three major parts of hair are Cuticle, Cortex, and Medulla.
Does water enter plants through root hairs?
water enters the plants through the root hair by osmosis. This is where water moves from an area of high concentration to an area of low concentration through a semi-permeable membrane.The root hair greatly increases the area for absorption.
What part of a root transports water and nutrients?
A. epidermis B. root cap C. vascular systems D. cortex
What is the structure of root hair cells?
The root hair cells has a special structure to help it absorb water from the soil efficiently. 1. Elongated structure that protrudes out to the soil - This is to increase the surface area to volume ratio; thereby increasing the rate of uptake of water from the soil to the cell. 2. Large vacuole - The root hair cell has a large vacuole to maximize the amount of water capacity of the cell; thus, the cell is able to absorb and store more water. 3. Cell sap - The cell sap of the root hair cell has a lower water potential than the water in the soil. Thus, the water from the soil moves into the cell via osmosis.
What is the function of passage cells in the endodermis of root?
In endodermis the passage cells passes the water molecules from the cortex to the protoxylem. Passage cells prevent the re entry of water molecules into the cortex.
