What gas is used to break apart sugar during respiration?

Which cells are responsible for opening and closing stomata to regulate water loss & gas exchange?

• Guard cells are highly specialised
• Two guard cells on each stomata
• Guard cells are bean shaped
• Responsible for opening and closing of stomata for gaseous exchange.

What type of sugar molecule is produced by plants during photosynthesis?

• Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose.
• Glucose is used by plants for energy and to make other substances like cellulose and starch.

What are the reactants for photosynthesis?

• After completion of photosynthesis, it releases oxygen and produces carbohydrates.

What is the energy source for photosynthesis?

• Sunlight is required for excitation of electron from electron center .

All organisms need food, what are the two main ways of how organisms get their food?

• All the heterotrophs are dependent for their food on autotrophs.
• Autotrophs are the producers in food chain.
• Plants and algae are the main source of food on Earth for all the living things directly or indirectly.

This picture is a good example of

All living things are made of

• Cells are the basic unit of life.
• All the living things are made up of cells.
• The living things may be unicellular ( single celled) or multicellular ( multiple celled).

Which organisms normally perform photosynthesis?

• All the photosynthetic organisms are called autotrophs.
• Autotrophs are the producers in food chain.

What is one of the 3 products of cellular respiration?

The overall equation of cellular respiration is:-

•  6glucose + 6 oxygen= 6 carbon dioxide+ ATP +6 water
• Cellular respiration is the process in which the food we eat is broken down to release energy in the form of ATP.

Where does CO₂ enter the leaves through?

• Stomata are responsible for the exchange of gases in plants.
• Stomata are the tiny pores present on leaves.
• The tiny pores are enclosed by guard cells and subsidiary cells.

Pigment in green plants that captures the energy in sunlight is called _______.

• Chlorophyll is green coloured pigment.
• It traps sunlight for photosynthesis.
• It present in chloroplast.

What is one of the ‘ingredients’ for photosynthesis?

• Within the plant cell, the water is oxidised, means loses electrons. And carbon dioxide is reduced, means it gains electrons.
• This transforms, the water into oxygen and carbon dioxide into glucose.

Where does photosynthesis take place in the plant cell?

• Chloroplasts are surrounded by a double membrane.
• And it contains a third inner membrane, called thylakoid membrane.
• The thylakoid membrane forms long folds within the organelle.

How does a heterotroph get energy?

Chemosynthesis is the process of production of food in heterotrophs by using chemical energy stored in inorganic molecules.

How do autotrophs get their food?

Photosynthesis is the process in which autotrophs create their own food by converting carbon dioxide into glucose and water into oxygen.
