Question:

The main parts of the lamina of the dorsiventral leaf are

Options:

1. epidermis
2. mesophyll tissues
3. vascular system
4. All of the above

Solution:

The lamina of a dorsiventral leaf, also known as a bifacial leaf or a dicot leaf, has two distinct sides: an upper side and a lower side. The upper side is called the adaxial surface and the lower side is called the abaxial surface. The main parts of the lamina of a dorsiventral leaf include: Epidermis: The outermost layer of cells that covers both the adaxial and abaxial surfaces of the leaf. Mesophyll tissues: The tissue between the two epidermal layers of the leaf, which is mainly responsible for photosynthesis. The mesophyll tissues include the palisade parenchyma and the spongy parenchyma. Vascular system: The system of veins that transports water, minerals, and nutrients throughout the leaf. The vascular system includes the xylem and the phloem.
