Question 6 (2 points) What is the name of the middle layer of a leaf where photosynthesis occurs? Epidermis b Mesophyll xylem d Phloem

## Step 1<br />The question asks for the name of the middle layer of a leaf where photosynthesis occurs. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. <br /><br />## Step 2<br />In the context of plant anatomy, the leaf is the primary site of photosynthesis. The leaf is composed of three main layers: the epidermis, the mesophyll, and the vascular bundles (xylem and phloem).<br /><br />## Step 3<br />The epidermis is the outermost layer of the leaf, which serves as a protective layer. It is not the site of photosynthesis.<br /><br />## Step 4<br />The xylem and phloem are part of the vascular system of the plant. The xylem is responsible for the transport of water and nutrients from the roots to the rest of the plant, while the phloem is responsible for the transport of sugars (food) from the leaves to the rest of the plant. Neither of these is the site of photosynthesis.<br /><br />## Step 5<br />The mesophyll is the middle layer of the leaf, which is the primary site of photosynthesis. It contains a large number of chloroplasts, which are the organelles where photosynthesis takes place.
