Question

Bulliform or motor cells are present in

• A. Dicot stem
• B. Upper epidermis of dicot leaves
• C. Upper epidermis of monocot leaves
• D. Lower epidermis of monocot leaves

Answer 1

The correct option is D

Lower epidermis of monocot leaves

The correct answer is d.

Explanation for the correct answer

Option d

1. Bulliform cells are the big, bubble-shaped epidermal cells that are found on the upper surface of monocot plants' leaves.
2. They aid in the development of newly formed leaves.
3. In reaction to alternating wet and dry times, it is engaged in the rolling and unrolling of adult leaves.

Explanation for incorrect option

Option (a)

1. Dicot stems have a dermal layer, multicellular stem hair, and a clearly defined epidermis with a cuticle.
2. A dicot stem's internal structure is primarily made up of pith, pericycle, hypodermis, cortex endodermis, and epidermis.
3. Dicot stems include things like sunflower and Cucurbita.

Option (b)

1. The epidermis is located underneath the cuticle.
2. This is the upper epidermis, which is located at the top of the leaf.
3. The cuticle is immediately followed by a single layer of cells called this.
4. By assisting in stopping water loss and adding another layer between the leaf's outside and interior, it protects the leaf.

Option (c)

1. The cuticle, an exterior, waxy covering that protects the upper and lower epidermis' dermal tissue, is present on monocot and dicot leaves.
2. The leaf's cuticle keeps it safe and aids in water retention.
3. The leaf is additionally shielded by the epidermis, which is situated underneath the cuticle.

Final answer:

Bulliform Or Motor Cells Are Present In Lower Epidermis Of Monocot Leaves.
