There are two basic forms of leaves that can be described considering the way the blade (or lamina) is divided. Leaves may be simple or compound. Simple and compound leaves: Leaves may be simple or compound. In simple leaves, the lamina is continuous.
Which part of the plant forms leaves?
stem
Such roots are known as pneumatophores. The stem is the part of the plant which is found above the ground. The bark of trees are brown in colour and younger stems are green in colour. It forms the basis of the shoot system and bears leaves, fruits and flowers.
How the leaves are formed?
Leaves are structures which are derived from stems. The initial stages of leaf formation are the same for monocots and dicots. Variations in morphogenesis between the shoots of monocot and dicot plants occur at a later stage….Leaf formation.

What is a leaf base?
The leaf base is the slightly expanded area where the leaf attaches to the stem. petiole, when present, and the leaf base become thickened, and often the latter expands laterally and fully or partially encloses the stem.
Which is correct leaves or Leafs?

Why is it each plant has different formation of leaves?
However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll. The thickness, shape, and size of leaves are adapted to the environment. Each variation helps a plant species maximize its chances of survival in a particular habitat.
What are the 4 main functions of leaves?
As one of the most important constituents of plants, leaves have several essential functions:
- Photosynthesis.
- transpiration.
- guttation.
- storage.
What is base of plant?
In biology, ‘base’ means the part of a plant or animal organ that is near the point of attachment to the ground or to a more basal part of the body. In all standard text books on plant anatomy, including Plant Anatomy, the tips of shoots and roots are referred to as apices (Figure 1) [1].
What do you need to know about leaves?
Learn about Leaves. Leaves are the plants food factory. A leaf is a flat, thin plant organ that uses the sun to make its own food. In general leaves are green and use the chemical called chlorophyll to trap energy from the sun. This process is known as Photosynthesis.
How are the leaves of a plant used to make food?
Leaves are the plants food factory. A leaf is a flat, thin plant organ that uses the sun to make its own food. In general leaves are green and use the chemical called chlorophyll to trap energy from the sun. This process is known as Photosynthesis. The energy is used to combine water from the soil and carbon dioxide gas from the air to make sugar.
How are the leaves of a plant used for photosynthesis?
The leaf is the site of photosynthesis in plants. Photosynthesis is the process of absorbing energy from sunlight and using it to produce food in the form of sugars. Leaves make it possible for plants to fulfill their role as primary producers in food chains. Not only do leaves make food,…
What makes the leaves of a plant green?
The chlorophyll molecule, responsible for the green color in leaves, is made of carbon and nitrogen, and acts as the antennae to initiate photosynthesis. Atmospheric CO 2 enters the leaf and is “fixed” during photosynthesis to create simple sugars that plants (as well as humans and animals) use as building blocks for complex molecules.
