Characteristics of a Leaf
- The leaf is a lateral dissimilar appendage of the stem.
- A leaf is always borne at the node of the stem.
- Generally, there is always an axillary bud in the axil of a leaf.
- It is exogenous in origin and develops from the swollen leaf primordium of the growing apex.
- The growth of leaf is limited.
What are the characteristics of the leaf?

What are 3 main functions of a leaves?
Leaf contains minute pores called stomata where gaseous exchange and transpiration occurs. The main functions of leaves are photosynthesis, exchange of gasses and transpiration.
What are the 5 main characteristics of plants?

Which of the following is character of leaf *?
A flattened structure of a higher plant, generally green and blade-like is known as a leaf.
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 are the 10 uses of leaves?
- uses of leaves for plant:
- photosynthesis: preparation of food.
- respiration:break down of food into simpler form.
- transpiration: loss of water for cooling down the temperature and circulation of water required for various chemical reactions.
- guttation: removal of excess amount of water.
What are the 10 functions of a leaf?
Leaf function
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.
What is the importance of leaf?
Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen. Leaves also release excess water, much like we sweat.
What is the two main function of leaves?
Conclusion: The leaf carries out two important functions i.e. photosynthesis and transpiration.
What are the two main function of leaf?
The leaf is the green flattened structure that is the main site of photosynthesis and transpiration.
What are the 4 main characteristics of plants?

What are the 6 characteristics of plants?
Terms in this set (6)
- photosynthesis. makes food from sunlight- chlorophyll found in chloroplasts captures sunlight.
- Multi-cellular. made up of many cells.
- Autotrophic. make their own food using chlorophyll (throughout photosynthesis)
- Cuticle.
- Cell wall.
- sexual reproduction.
What are 3 characteristics of plants?
Land plants are multicellular organisms that can be distinguished from other living things by a number of characteristics: They make their own food. Plants are photosynthetic and contain a green pigment called chlorophyll, which enables plants to convert energy from the sun into food. Plants store their food as starch.
Which of the following is a characteristic feature of scale leaves?
Answer: The leaf is a lateral dissimilar appendage of the stem.
Which is the characteristic feature of the lamina of a leaf?
Lamina of the leaf is traversed by vascular strands, called veins.
Which of the following is the characteristics of Dicot leaf?
Dicotyledons or dicots are flowering plants whose seed contains two embryonic leaves or cotyledons. They have a tap root system. Leaves in dicots have reticulate or net venation.
What are the 7 parts of a leaf?
Apex: tip of the leaf • Margin: edge of the leaf • Veins: carry food/water throughout leaf; act as a structure support • Midrib: thick, large single vein along the midline of the leaf • Base: bottom of the leaf • Petiole: the stalk that joins a leaf to the stem; leafstalk • Stipule: the small, leaf-like appendage to a
How are leaves classified?
Leaves are classified as either alternate, spiral, opposite, or whorled. Plants that have only one leaf per node have leaves that are said to be either alternate or spiral. Alternate leaves alternate on each side of the stem in a flat plane, and spiral leaves are arranged in a spiral along the stem.
Why are leaves called leaves?
It comes from the Proto-Germanic *laubaz, a word for the same exact part of a plant that “leaf” refers to. Leaves is plural for leaf, which to the best of my knowledge have nothing to do with the verb leave.
