Question

What are the diffetent types of leaves according to their arrangement of leaves on the steam and their shapes​

Answer 1

Answer:

The arrangement of veins in a leaf is called the venation pattern; monocots have parallel venation, while dicots have reticulate venation. The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.

Answer 2

Tree and shrub identification begins when you assess the different parts of the plant and recognize their specific type, color, shape, and size. When these clues are pieced together, you can properly identify the species of the tree or shrub.

One such clue is the leaf arrangement on the stem, which is formally known as phyllotaxy in botany. There are three basic types of leaf arrangements found in trees and shrubs: alternate, opposite, and whorled.

In an alternate leaf arrangement, there is one leaf per plant node, and they alternate sides.

Examples of trees and shrubs with an alternate leaf arrangement:

Barberry (Berberis thunbergii)
Black walnut (Juglans nigra). The black walnut may appear to have an opposite leaf arrangement, but it has compound leaves. The opposite leaflets form the entire true leaf, which alternates on the stem.
Japanese zelkova (Zelkova serrata)
Ninebark (Physocarpus opulifolius)
Smoke bush (Cotinus coggygria)
Sweetgum (Liquidambar styraciflua
