What are two 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.
The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis..
What kind of food do the plants produce?
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.
What is the function of Stipule?
Purpose of stipules It is known that foliaceous stipules are used like leaves to make energy for the plants. Sometimes stipules protect the next leaf or bud as it grows in then falls off after the leaf unfolds, as with Tulip Poplars. Stipules can be used as climbing tendrils by climbing plants.
What are leaves without petiole called?
Structure of a Typical Leaf Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Leaves also have stipules, small green appendages usually found at the base of the petiole.

Is celery a petiole?
Celery stalks are the petioles (“stalks”) of compound leaves. They are not stems, in spite of widespread misrepresentation in elementary school lesson plans. They may look like stems to some people because they are thick and fleshy and have prominent veins running lengthwise through them.
What are the two main functions of a leaf?
Manufacturing of food/ photosynthesis: the main function of leaves is to manufacture food. Food is manufactured in the presence of sunlight by leaves that contain a green pigment called chlorophyll. … Transpiration : excess water taken up by the plants is released into the air in the form of water vapour through stomata.
What are the two functions of leaves?
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.
What are the 4 functions of a leaf?
Which part of the leaf is called petiole?
In botany, the petiole (/ˈpiːtioʊl/) is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. … Leaves lacking a petiole are called sessile or apetiolate.
What does blade mean?

How does the petiole help in photosynthesis?
Petiole Function Since leaves are responsible for fueling plants through photosynthesis, the petiole serves to transport the energy made in the leaf to the rest of the plant. It also serves to transport nutrients and water that are absorbed by the roots and passed up through the xylem, to the leaf.
What does petiole mean?
1 : a slender stem that supports the blade of a foliage leaf. 2 : peduncle specifically : a slender abdominal segment joining the rest of the abdomen to the thorax in some insects.
What is the function of the blade of a leaf?
The blade is the broad part of a leaf that holds the green food making cells. The petiole is the stemlike part of the leaf which holds the blade. A leaf petiole is not merely the handle which holds the leaf to the plant it must also carry food made by the leaf to all parts of the plant.
What is winged petiole?
Complete answer: Winged petiole is the one in which there is a thin flange of tissue along the length of the petiole. … It is a green and flattened petiole. Plants like Citrus and Dionaea have winged petiole in them. This also gives a characteristic foliage arrangement to the plant.
