44. Point out the differences in the anatomy of leaf of peepal (Ficus religiosa) and maize (Zea mays). Draw the diagrams and label the differences.

 

Difference between Ficus leaf and maize leaf is as follows

 Character

 Ficus leaf (Dicot Leaf) 

Maize leaf (Monocot Leaf)

Type of leaf

Dorsiventral

Isobilateral.

Stomata

Usually more on lower epidermis

Equal on both, lower and upper epidermis.

Mesophyll

Made up of two types of tissues

(a) Lower spongy parenchyma with large intercellular spaces.

(b) Upper palisade parenchyma.

Only spongy parenchyma is present which has very small intercellular spaces.

Bundle sheath

Made up of parenchyma. Just above and below the vascular bundle some
parenchymatous cells or collenchymatous cells are present (up to epidermis).

Made of parenchyma, but just above and below, the vascular bundles are found sclerenchymatous cells (up to epidermis).

Bulliform cells

Absent in dicot leaves.

Present, particularly in grasses (monocot leaves).
