What's the name of the characteristic where living things get rid of waste?

What gas is used to break apart sugar during respiration?

• Oxygen is used to breakdown glucose into carbon dioxide and water.
• The breakdown of glucose occurs in the cells of an organism.

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.
