What are features of leaves?
The leaves do not possess any apical bud or a regular growing point. A leaf has three main parts – Leaf base, petiole and leaf lamina. In addition, it may possess two lateral outgrowths of the leaf base, called stipules. The leaf lamina is traversed by prominent vascular strands, called veins.
What are the special features of a leaf cell?
Like other plant cells, the leaf cell is eukaryotic. In addition to a nucleus within a membrane, a leaf cell has mitochondria, a central vacuole and sometimes chloroplasts containing cholorophyll. Cytoplasm is contained within a cell wall. Deciduous leaves are thin and flat to facilitate photosynthesis and respiration.
What are the 4 functions of a leaf?
As one of the most important constituents of plants, leaves have several essential functions:
- Photosynthesis.
- transpiration.
- guttation.
- storage.
What are 3 functions of the 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 is the main function of the leaf?
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.
What are the 5 types of leaves?
There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant.
What is the main function of a leaf cell?
What are the 4 types of cells in a leaf?
Types of Leaf Cell
- Epidermis. An epidermal leaf cell is any cell which protects the outside of the leaf.
- Palisade Mesophyll. The palisade mesophyll consists of a type of leaf cell specifically designed to carry out photosynthesis.
- Spongy Mesophyll.
- Vascular Bundle.
What is the main function of a leaf?
What are the 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 5 functions of leaves?
As one of the most important constituents of plants, leaves have several essential functions:
- Photosynthesis.
- Transpiration.
- Guttation.
- Storage.
- Defense.
- Conifer Leaf.
- Microphyll Leaf.
- Megaphyll Leaf.
What is the primary function of leaves?
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Where are the different parts of a leaf located?
Key Points 1 Leaves are found at the nodes of the stem and contain the photosynthetic pigment chlorophyll. 2 There are three main parts of a leaf – Leaf base, leaf lamina, and petiole. 3 There are two different types of leaves – simples leaves and compound leaves. Mas cosas…
What are the main functions of a leaf?
What is the structure of a leaf? All leaves have the same basic structure – a midrib, an edge, veins and a petiole. The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive. Plants provide food for all life on the planet.
What kind of leaves are flat with a petiole?
A ternate compound leaf with a petiole but no rachis (or rachillae) Bipinnate leaf anatomy with labels showing alternative usages Leaves of most plants include a flat structure called the blade or lamina, but not all leaves are flat, some are cylindrical. Leaves may be simple, with a single leaf blade, or compound, with several leaflets.
What are the different types of compound leaves?
A compound leaf is a leaf made up of two or more leaflets. In a compound leaf, the midrib of the leaf is branched into different leaflets and is connected by a single petiole. For eg., Pea, palm leaves. The compound leaves are further sub-divided into the following types of leaves:
What are the characteristics and functions of a leaf?
Parts 4. Types 5. Modification 6. Functions 7. Importance. Leaf is a green, dissimilar exogenous lateral flattened outgrowth which is borne on the node of a stem or its branch and is specialised to perform photosynthesis. Typically it is a thin expanded green structure which bears a bud in its axil.
What are the different types of tree leaves?
Some patterns in tree leaf venation include the following: Pinnate veins branch out in opposite directions from the central vein that runs the length of the leaf Palmate capillaries branch out from the midvein to form the shape of a leafless tress

What kind of leaf looks like a blade of grass?
Long, wider in the middle, shaped like a lance tip. Long and very narrow like a blade of grass. Being divided by clefts, may be pinnately lobed or palmately lobed. Having the form of a thong or strap. Shaped like a lyre, pinnately lobed leaf with an enlarged terminal lobe and smaller lateral lobes.
