Monocots usually do not have a midrib and the blade is more uniform in its thickness. Because the large veins in monocot leaves lie parallel to one another, they are cut at a 90 degree angle in a cross section. Consequently, they produce a highly organized profile.

What are the differences between a monocot and dicot leaf?

Monocot leaves are narrow, slender, and longer than dicot leaves. Dicot leaves are broad and relatively smaller than monocot leaves. Monocot leaves are isobilateral in symmetry. Dicot leaves are dorsoventral as the upper and lower surfaces of the leaves are distinguished.

What do most monocots not have?

Monocots usually don't have secondary growth. Some, such as bamboo and palm trees, have secondary growth. Monocot secondary growth differs from dicot secondary growth in that new bundles are formed at the edge of the stem. These new bundles are close together, providing support for the stem.
