Answer 2

Mesophyll layer is the largest manufacturer of carbohydrates in leaf.

Explanation:

Chloroplasts are the main manufacturers of carbohydrates and chloroplasts are found in Mesophyll layer of leaf.

There are mainly three layers in a leaf:

1. Epidermis - It is the outermost layer and secretes a waxy substance called the cuticle. The cuticle helps retain water inside the leaf cells. The epidermis houses the guard cells which regulate the movement of water into and outside the cell. Guard cells do so by controlling the size of the pores also called stomata.
2. Mesophyll - This forms the middle layer of the leaf. It is differentiated into two layers depending on the type of cells found: palisade and spongy mesophyll layers. It is in this layer that the chloroplasts are found. Chloroplasts are cell organelles that contain chlorophyll which is required for photosynthesis. The vascular tissues of the leaf are contained in the irregularly arranged spongy mesophyll cells.
3. Vascular Tissue/Veins - The vascular tissue is actually found in the veins of the leaf. The vascular tissues are composed of xylem and phloem which are responsible for the transport of water and food.
4. Lower Epidermis - A protective layer of cells. The lower epidermis produces a waxy cuticle too in some plant species. The lower epidermis contains pores called stomata that allow carbon dioxide and oxygen to move in and out of the plant respectively.
5. Stomata - Tiny pores (small holes) surrounded by a pair of sausage shaped guard cells. These cells can change shape in order to close the pore.
