write necessary conditions for autotrophic nutrition and its by products
Answers
1. Presence of chlorophyll in the living cells.
2. Provision of supply of water to green parts or cells of the plant either through roots or by surrounding environment.
3. Availability of sufficient sunlight to provide the energy required to carry out photosynthesis.
4. Sufficient supply of carbon dioxide which is one of the important components for the formation of carbohydrates during photosynthesis.
The by-products of autotrophic nutrition are starch (carbohydrate) and oxygen.
Conditions for photosynthesis Below are things that plants need for photosynthesis: bulletCarbon dioxide (A colorless, naturally occurring odorless gas found in the air we breathe. It has a scientific symbol CO2. CO2 is produced by burning carbon and organic compounds. It is also produced when plants and animals breathe out during respiration) bulletWater bulletLight (Even though both natural and artificial light is OK for plants, natural sunlight is usually great for photosynthesis because they have other natural UV properties that help the plant) bulletChlorophyll (This is the green pigment found in the leaves of plants) bulletNutrients and minerals (Chemicals and organic compounds which the plant roots absorb from the soil) Below are things that plants make by photosynthesis: bulletGlucose bulletOxygen
