Xylem, Stomata and Guard Cells
Xylem, Stomata and Guard Cells
Xylem: Pipe-like vessels present inside the roots, stem, branches and the leaves which form a continuous passage for water, minerals and other nutrients to reach the leaves from the root
Stomata: Tiny pores present on the underside of leaves which help in the exchange of gases. Stomata is bounded by two half-moon shaped guard cells. These guard cells regulate the opening & closing of stomata when there is enough light & water. These guard cells swells up and curve away from each other & stomata open this allows CO2 to enter the cells of the leaf.
Guard cells: These surround the stomata and regulate their opening and closing.

8thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
