Question

Which of the following is true about a monocot leaf?
A. Reticulate venation
B. Absence of bulliform cells from epidermis
C. Mesophyll not differentiated into palisade and spongy tissues
D. Well differentiated mesophyll

Answer 1

Morphology of monocot leaves are parallel venation leaves are isobilateral in the leaf mesophyll is undifferentiated ant its show spongy tissue parenchyma and shape in an oval.

Complete answer:
Monocot leave is isobilateral and amphistomatic with dumbbell-shaped upper epidermis possesses groups of larger sized thin-walled vascular cells called Bulli form or motor cells. Monocot leaves are parallel venation in maize leaf and show its own structure and its transverse section passing through a midrib region. In monocot leaf epidermis are in two layers on each surface of the leaf epidermal layers are made of compactly arranged and shape ate in barrel-shaped cells. In both layers Cuticle and trichrome are present. Stomata are found in both the epidermal layers.
In option A: Reticulate venation are found in leaves it is a type of classification of the vein and it is found in Rosses, oak trees, and maple trees so this option is not correct.
In option B: Bulli form cells are found in all monocot leaves but it is absent in dicot leaf so this option is not correct.
In option D: Well-differentiated mesophyll found in plant leaves and it is found in the dicotyledonous plant so this option is not correct.

So, the correct answer is option C.

Additional Information: Mesophyll is ground tissue that occurs between the two epidermal layers. Composed of many layers of loosely arranged, spherical chlorenchyma cells. Intercellular spaces are prominent.

Note:
Veins are found parallel arranged in the mesophyll. Each vascular bundle is surrounded by a bundle sheath composed of a single layer of the compactly arranged barrel in shaped cells. The bundle sheath encloses both phloem and xylem.
