10. Draw and label different tissues revealed under transverse section of a
dorsiventral leaf.
Answers
The image given below shows the transverse section of dorsoventral leaf
Explanation:
- the uppermost structure includes the cuticle which prevents loss of water. It is followed by the epidermis. then comes the palisade cells which are very tall cells and occupy most part of the leaf. Then comes the endodermis.
- Within the endodermis is the the stomatal pore where exchange of gases and transpiration takes place. In case of monocot leaf there should be stomata in both type of the leaf

Answer:
Concept:
Labeling different tissues revealed under the transverse section of a
dorsiventral leaf. Dicots have dorsiventral leaves. A dorsiventral leaf has three different sections that make up its vertical section.
Explanation:
1) Epidermis: Adaxial epidermis, which covers the upper surface, and basal epidermis are both covered by epidermis (abaxial epidermis). A thick cuticle surrounds the epidermis on the exterior. More stomata are present in the abaxial epidermis than the adaxial epidermis.
2) Mesophyll: Mesophyll is a leaf tissue located between the adaxial and abaxial epidermis. It is divided into the spongy parenchyma and the palisade parenchyma, which are both made up of tall, tightly packed cells (comprising oval or round, loosely-arranged cells with inter cellular spaces). Chloroplasts, which are responsible for photosynthesis, are found in mesophyll.
3) The vascular system: Which consists of the conjoined and closed xylem and phloem conducting tissues, is present in the veins of leaves. They aid in the movement of water, food (glucose), and minerals and are encircled by extensive layers of bundle-sheath cells.
