Shape of the Leaf
- Cordate: Heart shaped, with a sharp tip at the apex and the petiole coming out between the rounded parts of the heart at the leaf base.
- Elliptical: Longer than wide, but tapers at both ends.
- Lanceolate: Longer than wide, but tapers smaller at the apex.
- Linear: narrow and the same width at both ends.
What is a simple definition of leaf?

What does a leaf look like?
Most leaves have a broad, flat part called a blade. Different types of leaves may be rounded, oval, spear shaped, heart shaped, or triangular. Some leaves look almost like fingers on a hand. Others are shaped like needles.
What are the features of a leaf?
Features of leaves
| Adaption | Purpose |
|---|---|
| Thin | Short distance for carbon dioxide to diffuse into leaf cells |
| Chlorophyll | Absorbs sunlight to transfer energy into chemicals |
| Network of veins | To support the leaf and transport water and sugars |
| Stomata | Allow carbon dioxide to diffuse into the leaf and oxygen to diffuse out |
What is leaf with example?

What are the 3 main functions of leaves?
The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water.
What are the 5 functions of a leaf?
As one of the most important constituents of plants, leaves have several essential functions:
- Photosynthesis.
- Transpiration.
- Guttation.
- Storage.
- Defense.
- Conifer Leaf.

- Megaphyll Leaf.
What are 3 functions of a leaf?
What are two functions of a leaf?
The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.
What are the technical terms used to describe leaves?
The Description of Leaves There are a number of technical terms used for describing the arrangement and shape of leaves. These terms can be divided into several groups: Terms describing the arrangementof the leaves on the stem Terms describing the general structureof the leaf Terms describing the edge or marginof the leaf
What is the function of the leaves of a plant?
Leaves are the primary sites of photosynthesis and manufacture food for plants. They are an integral part of the stem system and can be modified into a variety of other plant organs. Leaf, any usually flattened green outgrowth from the stem of a vascular plant.
What’s the difference between a leaf and a leaf compound?
Compound:show all Leaves divided into individual leaflets. Leaflets are distinguished from leaves in that there is no bud at the base. Leaves may be palmately or pinnately compound. Some are doubly or even triply pinnate. Terms describing the margin of the leaf Entire:show all Margins without teeth or serrations.
How can you tell the difference between leaves?
They may be: Color and texture are two other methods of categorizing foliage. In addition, you can look at any discrepancy in the leaf margin. The edges of leaves may be smooth, toothed, lobed, incised, or wavy. The degree of any of these conditions varies as well. Needle-like leaves also have distinguishing arrangements and shapes.
What are leaves and why are they important?
Leaf, in botany, any usually flattened green outgrowth from the stem of a vascular plant. As the primary sites of photosynthesis, leaves manufacture food for plants , which in turn ultimately nourish and sustain all land animals. Botanically, leaves are an integral part of the stem system.
What is a leaf of a plant?
A leaf can help a plant grow because a leaf has something called photosynthesis. Photosynthesis is the process in which plants use sunlight to synthesize foods from carbon dio…xide and water.
What are the characteristics of leaves?

- Characteristics of Leaf:
- petiole and lamina.
What is the function of leaves?
