What are some leaf shapes?

Why are there different shapes of leaves?
Why do tree leaves have different shapes? The shape of a tree’s leaves are a response to the tree species’ long term ecological and evolutionary histories. When these leaf stomatae are open to allow the uptake of carbon dioxide, water from inside the leaf is lost to the atmosphere.
What is the basic structure of a leaf?
Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.
What are the 5 types of leaves?
There are three main parts of a leaf – Leaf base, leaf lamina, and petiole. 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.
How do you identify different types of leaves?
Common leaf identification shapes include ovate (egg shaped), lanceolate (long and narrow), deltoid (triangular), obicular (round) and cordate (heart shaped). There is also the palm-shaped maple leaf and the lobed oak leaf, two of our most recognizable leaf shapes.
Is there an app to identify leaves?
Plantifier. Free on Android and iOS. This crowdsourced plant recognition app allows you to upload an image of an unknown plant; the users of the MyGarden.org community attempt to identify the plant and answer questions.

Undulate blades form a wavy line on their edge that bends slightly inward and outward in succession. Sinuate blades are wavy. Incised blades are sharp, deep irregular teeth. Lobed blades have rounded incisions that are not deeper than halfway between the edge and center of the leaf.
Why leaves are called kitchen of plant?
A leaf is actually called ‘the kitchen of the plant’. This is because they are the main organ responsible for photosynthesis, through which the plant produces its energy a.k.a. it’s food. They obtain their green color due to the presence of chlorophyll.
Which part of plant is known as kitchen?
Chloroplasts
What is called the kitchen of plants?
The chloroplast is called complete photosynthetic units because both the stages of photosynthesis, light reaction, and dark reaction are carried out within this one unit only. Chloroplasts are also known as the kitchen of the cell as it help plants in making food.
What does a simple leaf look like?
A simple leaf blade is undivided as shown on the left (though the margins may be toothed or even lobed). The blade of a compound leaf is divided into several leaflets as shown on the right. Each leaf, whether simple or compound, has a bud at its base (on the twig).
