It is the main photosynthetic organ of most vascular plants.
Leaves
It is the broad flattened structure of the plant containing the green pigment called chlorophyll which helps the plant from photosynthesis.
Leaf
What are the main functions of plant leaves?
Photosynthesis
Gas Exchange
Transpiration
It is the process of conversion of carbon dioxide and water to glucose and oxygen in the presence of sunlight.
Photosynthesis
What is the formula of photosynthesis?
6CO2 + 6H2O - (sunlight) -> C6H12O6 + 6O2
It refers to the diffusion of gases from an area of higher concentratio to an area of lower concentration.
Gas Exchange
This is where plants obtain the gases they need.
Leaves
What are the two process of gas exchange?
Photosynthesis
Respiration
It is a continuous process that takes place in the plants throughout the day and night.
Respiration
This gas exchange occurs only in the daytime in the presence of sunlight and oxygen.
Photosynthesis
During this gas exchange, carbon dioxide moves in through the stomata while the oxygen moves out.
Photosynthesis
Where do gas exchange takes place?
Stomata
What is the process of gas exchange?
Diffusion
During this gas exchange, oxygen enters the plant through the stomata, and carbon dioxide is released.
Respiration
It is the removal of excess water in the form of water vapor. It occurs by the opening of stomata present in the leaves.
Transpiration
It is the minute pores in the epidermis where gas exchange occurs.
Stomata
It is a waterproof covering made up of cutin, waxes, and polysaccharides. It is generally described as an extracellular thick waxy layer that covers the outside part of the epidermis, and helps plants conserve water.
Cuticle
These are two kidney-shaped cells found on the leaf epidermis and surrounds the stomata. It opens and closes the stomata and controls water loss within a leaf.
Guard Cells
What is the plural term of stoma?
Stomata
It is also called the "middle leaf."
Mesophyll
What are the two layers of Mesophyll?
Palisade
Spongy
It is a rectangular layer that creates a layer below the upper epidermis of the plant. It houses most of the leaf's chloroplasts, that is why it serves as the leaf's photosynthesis layer.
Palisade Layer
It is a layer of mesophyll found internally to the lower epidermis, and facilitates the exchange of gases.
Spongy Layer
It is the only layer of mesophyll present in monocots.
Spongy Layer
It is the outer layer of the leaf and it helps protect the leaf by aiding in preventing water loss and providing an extra layer between the outside and inside of the leaf.
Epidermis
It is the flattened surface (broad portion) of a leaf.
Blade
It is the tip of the leaf.
Apex
It is the leaf edge boundary area.
Margin
These are vascular tissue bundles that support the leaf and transport nutrients.
Veins
It is the central main vein arising from secondary veins. It helps the leaf to keep in an upright position.
Midrib
It is the area of the leaf that connects the blade to the petiole.
Base
It is a thin stalk that attaches the leaf to a stem.
Petiole
These are leaf-like structures at the leaf base.
Stipules
What are the two types of leaves?
Simple
Compound
This type of leaf contains a single leaf that attaches to the stem. It has a single blade or lamina and is not divided further into smaller leaflets.
Simple Leaf
The leaves of Banana and Hibiscus are...
Simple
This type of leaf is separated into distinct leaflets, each with its own small petiole (but without an axillary bud).
Compound Leaf
In this type of compound leaf, leaflets are present on the common axis called the rachis; leaves are arranged in the opposite manner.
Pinnately Compound Leaves
In this type of compound leaf, leaflets are attached at a single point of the petiole.
