Stomata present in leaves help the plant in
Stomata are small openings on the leaf surface that allow gases to move in and out of the leaf. They play a crucial role in evaporation by facilitating the process of transpiration.
The green pigment present in the leaf is
Chlorophyll is the green pigment found in leaves and is essential for photosynthesis as it captures light energy.
The material required for photosynthesis are
Photosynthesis requires water and carbon dioxide to produce glucose and oxygen using light energy.
Photosynthesis occurs during day time because it depends on
Photosynthesis depends on sunlight as the energy source to convert carbon dioxide and water into glucose and oxygen.
During night plants give out more
At night, plants undergo respiration, during which they take in oxygen and release carbon dioxide.
What is the function of the waxy layer on the upper surface of a leaf?
The waxy layer, or cuticle, on the upper surface of a leaf helps to prevent excessive water loss by evaporation.
Which part of the leaf contains chloroplasts for making food?
Chloroplasts are primarily found in the palisade mesophyll layer, which is part of the upper skin of the leaf, where they can efficiently capture sunlight for photosynthesis.
Why are leaves called “food factories”?
Leaves are called "food factories" because they perform photosynthesis, a process that uses sunlight to convert carbon dioxide and water into glucose, which serves as food for the plant.
What is the function of stomata in the leaf?
Stomata are small openings on the leaf surface that facilitate gas exchange, allowing carbon dioxide to enter the leaf and oxygen to exit.
Where are stomata mostly found on a leaf?
Stomata are mostly found on the lower surface (lower skin) of the leaf to minimize water loss and facilitate efficient gas exchange.
What is transported through the tubes in leaf veins?
Leaf veins contain vascular bundles that transport water from the roots and food (glucose) produced by photosynthesis throughout the plant.
What green plants use to make their own food?
Green plants use carbon dioxide and water in the presence of sunlight to produce glucose and oxygen through the process of photosynthesis.
Where does photosynthesis occur in plant cells?
Photosynthesis occurs in the chloroplasts of plant cells, where chlorophyll captures light energy to convert carbon dioxide and water into glucose and oxygen.
Which green chemical is essential for photosynthesis?
Chlorophyll is the green pigment essential for photosynthesis as it captures light energy.
What are the two main products of photosynthesis?
The two main products of photosynthesis are glucose, which serves as food for the plant, and oxygen, which is released into the atmosphere.
What happens to some of the glucose produced in photosynthesis?
Some of the glucose produced in photosynthesis is converted to starch and stored for later use by the plant.
Why are leaves broad and flat?
Leaves are broad and flat to maximize the surface area exposed to sunlight, thereby enhancing the process of photosynthesis.
Which leaf part is responsible for gas exchange?
Stomata are responsible for gas exchange in leaves, allowing carbon dioxide to enter and oxygen to exit.
What is the role of veins in the leaf?
Veins in the leaf carry water from the roots and transport glucose produced by photosynthesis to other parts of the plant.
Which of these helps the leaf in maximizing photosynthesis?
A large surface area helps the leaf maximize photosynthesis by capturing more sunlight.
What is the correct word equation for photosynthesis?
The correct word equation for photosynthesis is: Carbon dioxide + Water → Glucose + Oxygen.
Which factor increases the rate of photosynthesis as its intensity increases?
Light intensity increases the rate of photosynthesis as it provides the energy needed for the process.
What is the role of chlorophyll in photosynthesis?
Chlorophyll traps sunlight and uses its energy to convert carbon dioxide and water into glucose during photosynthesis.
Why do leaves appear green?
Leaves appear green due to the presence of chlorophyll, the green pigment involved in capturing light energy for photosynthesis.
Which of the following is absorbed from the soil to help in photosynthesis?
Water is absorbed from the soil and is one of the essential materials required for photosynthesis.
From where do plants get carbon dioxide for photosynthesis?
Plants get carbon dioxide for photosynthesis from the air through small openings in the leaves called stomata.
What is the main purpose of respiration in plants?
The main purpose of respiration in plants is to release energy stored in glucose for various cellular activities.
What happens during photosynthesis?
During photosynthesis, light energy is trapped and used to convert carbon dioxide and water into glucose and oxygen.
Which of the following is used in respiration?
Respiration uses glucose and oxygen to release energy, producing carbon dioxide and water as by-products.
Which process occurs in all living organisms?
Respiration occurs in all living organisms as it is essential for releasing energy required for various life processes.
What is the main product of photosynthesis?
The main product of photosynthesis is glucose, which serves as food for the plant.
Which gas is produced during respiration in plants?
During respiration in plants, carbon dioxide is produced as a by-product.
What happens to carbon dioxide during photosynthesis?
During photosynthesis, carbon dioxide is used along with water to produce glucose and oxygen.
When do plants give out more carbon dioxide than they take in?
Plants give out more carbon dioxide than they take in at night because photosynthesis does not occur in the absence of light, while respiration continues.
How are respiration and photosynthesis related?
Respiration and photosynthesis are related as opposite processes: photosynthesis produces glucose and oxygen, which are used in respiration to release energy, producing carbon dioxide and water.
Which of the following is a food-using process?
Respiration is a food-using process where glucose is broken down to release energy.
What is the source of energy used in photosynthesis?
The source of energy used in photosynthesis is sunlight, which is captured by chlorophyll.
In which process is glucose broken down?
Glucose is broken down during the process of respiration to release energy.
What gas do plants take in during photosynthesis?
During photosynthesis, plants take in carbon dioxide from the air to produce glucose and oxygen.
Which of these only occurs in green plants?
Photosynthesis only occurs in green plants and some algae and bacteria, as it requires chlorophyll to capture light energy.
