(b) Light and dark reactions (products formed)
(c) Producers and consumers (mode of nutrition)
(d) Grass and grasshopper (mode of nutrition)
(e) Chlorophyll and chloroplast (part of plant cell)
Solution :
- Respiration and photosynthesis ( gas released )
| Respiration | Photosynthesis |
| All animals and plants , respire by oxidizing carbohydrates in their cells to generate energy and release carbon dioxide into the atmosphere. | Green plants which are the producers utilize carbon dioxide of the air to generate carbohydrates and give out oxygen to the atmosphere. |
- Light and dark reactions (products formed)
| Light reaction | Dark reaction |
| Light reaction involves the trapping of energy by chlorophyll, and this energy is utilized in splitting water molecules into hydrogen and oxygen (photolysis) and in giving rise to ATP. | Dark reaction includes the carrying of hydrogen from NADPH via a series of chemical reaction, to combine with CO2 to generate C6H12O6 by using energy from ATP. |
- Producers and consumers (mode of nutrition)
| Producers | Consumers |
| All green plants manufacture their own food. Therefore, they are called autotrophs (self-nutrition). | Animals obtain their food from plants either directly by eating their part, or indirectly by eating the plant-eater. Animals are heterotrophic (different nutrition) |
- Grass and grasshopper (mode of nutrition)
| Grass | Grasshopper |
| Grass is a producer. It manufactures its own food by photosynthesis. | The Grasshopper eats up the grass |
- Chlorophyll and chloroplast (part of plant cell)
| Chlorophyll | Chloroplast |
| Chlorophyll is the green colouring matter seen in plants. It is present in microscopic cell organelles called chloroplasts. | Chloroplasts are minute oval bodies bounded by a double membrane, and their interior contains closely packed flattened sacs arranged in piles lying in a colourless ground substance called the stroma. |
