A student investigated the number of stomata pores on the upper and lower surface of a leaf. Stomata are tiny pores present on the surface of leaves. Massive amounts of gaseous exchange takes place in the leaves through these pores for the purpose of photosynthesis. But it is important to note here that exchange of gases occurs across the surface of stems, roots and leaves as well. The guard cells swell when water flows into them, causing the stomatal pore to open.
Question. Name the pores in a leaf through which respi-ratory exchange of gases takes place.
(a) Xylem
(b) Stomata
(c) Lenticels
(d) Vacuoles
Answer : B
Question. Stomata guard cells perform all functions but
(a) Chloroplast storage
(b) Regulating the amount of water lost

(a) Looses it turgor pressure
(c) Exposed to strong wind
(b) Looses its central vacuoles
(d) Looses its central nucleus
Answer : A
The leaf is the main photosynthesis organ in a plant. It controls gas exchange in plants, controls the amount of water loss in plants. Upper epidermis cells contain no chloroplasts – which is not true for the guard cells. They form layers on the upper and lower surfaces of the leaf. Their function is to prevent water from getting out and stopping unwanted substances/ organisms getting in. The palisade mesophyll layer is where most of the photosynthesis occurs in the leaf. The palisade cells contain a lot of chloroplasts to help them perform this photosynthesis. Lower epidermis is the bottom layer of the leaf, and is one cell thick. They may not contain a cuticle within the lower epidermis, there are some holes found in leaves called stoma. These holes allow gases to diffuse in and out of the leaves. The stoma are formed by two highly specialised epidermis cells, called guard cells. Guard cells are the only epidermis cells that contain chloroplasts.
Question. Where are chloroplasts present in the leaf?
(a) Upper epidermis
(b) Guard cells and Palisade cells
(c) Inner membrane
(d) Outer membrane
Answer : B
Question. Select the statement which is not correct regarding upper epidermis
(a) Upper epidermis contains large number of stomata.
(b) This is a single layer of cells containing few or no chloroplasts
(c) The upper surface is covered with a waxy, waterproof cuticle
(d) None of the above
