Question

Choose the correct statement with reference to the internal structure of leaves.

• A. All dicot leaves have an equal number of stomata on both surfaces of their leaves
• B. Conjoint vascular bundles are found in leaves
• C. Upper epidermis is called the abaxial epidermis and lower epidermis is called the adaxial epidermis
• D. Leaves have cambium

Answer 1

The correct option is B Conjoint vascular bundles are found in leaves

Vascular bundles in the leaf have xylem and phloem along the same radius and this type of vascular bundle is called conjoint.

Dicot leaf has more number of stomata in the lower epidermis when compared to the upper epidermis.
The upper epidermis of the leaf is called the adaxial epidermis and lower epidermis is called the abaxial epidermis.
Leaves lack cambium and hence there is no secondary growth in leaves.
