What is leaf morphology?

Morphology is the study of science that deals with the form and structure of an organism. Morphology of leaves deals with the study of the structural features and parts of a leaf.

What are 5 types of leaves?

Types of Leaves

  • Acicular type: They are needle-shaped.
  • Linear Type: They are long and relatively broader as compared to other leaves.
  • Lanceolate Type: They are lance-shaped.
  • Oblong Type: They are rectangular in their shape and structure.
  • Reniform type: They refer to the leaves with the shape of kidneys.

How do you classify a leaf?

Identify whether a leaf is simple or compound. If one leaf grows off one stem, it has a “simple” structure. If one leaf stem carries three or more leaves, the plant has a “compound” leaf structure. Leaves with “teeth,” or a serrated, jagged edge, help classify the type of plant, like an elm tree.

What features of Arabidopsis thaliana makes it a preferred model for plant development?

A. thaliana is easy to look after compared with animal model organisms. It grows quickly, produces many very small seeds, has a small genome ~114.5 Mb and is genetically well characterised due to the volume of work being focused on this plant.

How do you determine the shape of a leaf?

Leaf Edges or Margins

  1. Entire Leaf: The margin is even and smooth around the entire leaf edge.
  2. Toothed or Serrated Leaf: The margin has a series of toothlike pointed teeth around the entire leaf edge.
  3. Lobed Leaf: The margin has an indention or indentions that go less than halfway to the leaf midrib or midline.

How do you identify leaf arrangements?

There are two classifications you need to know for tree identification:

  1. Pinnate Venation: The veins extend from the midrib to the leaf margin. Oak and cherry tree leaves have pinnate venation.
  2. Palmate Venation: The veins radiate in a fan shape from the leaf petiole. Examples include maple and sweetgum leaves.

What are the four major leaf arrangements?

The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.
