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 4 functions of a leaf?
- Photosynthesis.
- transpiration.
- guttation.
- storage.
What are the main functions of a 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 2 main functions of leaves?
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 functions of a leaf answer?
Its main functions are
photosynthesis and gas exchange
. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
Why are leaves important to humans?
It's also a fact that wildlife and insects depend on leaves for food and shelter and humans like fruit, nuts and oxygen. …
Leaves take in carbon dioxide and give off oxygen
. Photosynthesis allows leaves to make food for the tree; when leaves fall, they decompose and become mulch and fertilizer.
What is leaf and its function?
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 are the function of fruits?
The function of fruits: A fruit
protects the immature seeds from animals and extreme climatic conditions
. It stores food material. It attracts animals that help in dispersing or scattering the seeds to distant places.
What is the main function of leaves Quizizz?
What is the main function of leaves? Leaves
provide support for growth and a place to store food
. Leaves provide a place for photosynthesis to occur. Leaves absorb water and minerals and transport nutrients to the stem.
What is a leaf made of?
Leaf tissue consists of
the epidermis
, which forms the outermost cell layer, and mesophyll and vascular tissue, which make up the inner portion of the leaf. In some plant species, leaf form is modified to form structures such as tendrils, spines, bud scales, and needles.
What are the main parts of a leaf?
Key Points
Each leaf typically has
a leaf blade ( lamina ), stipules, a midrib, and a margin
. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
What are the uses of leaves?
The main job of a leaf is
to make food
(see left navigation for a separate page about this) for a plant. Leaves do this by using sunlight for energy to take apart water from the ground and carbon dioxide from the air. Leaves use parts of water and carbon dioxide to make sugar.
What are the functions of flower?
The function of a flower is
to carry out sexual reproduction in plants through the formation of male and female gametes
. Flowers ensure that the gametes fertilise to form seeds that further help in reproducing plants.
What is the role of flower?
The primary purpose of the flower is
reproduction
. Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
What is petiole function?
A petiole
attaches the leaf to the stem
and contains vascular tissue that provides a connection from the stem to permit sap to enter the leaf and the products of photosynthesis (carbohydrates) to be transported from the leaf to the rest of the plant.
