Define photosynthesis 5 marks question .

Answer 1

Answer: The process by which green plants make their own food from carbon-dioxide and water in the presence of sunlight and chlorophyll is called photosynthesis.

Step 1-Light Dependent. CO2 and H2O enter the leaf.

Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

Step 3- Light Dependent. The electrons move down to enzymes.

Step 4-Light Dependent. ...

Step 5-Light independent. ...

Step 6-Light independent. ...

Answer 2

Explanation:                                                                                                   Photosynthesis is the process done by plants to make their own food and to give us Oxyg Equation for Photosynthesis:

Co2 + H20 → Sunlight and Chlorophyll → C6H12O6 + 6O2 + 6H2O

The different steps involved in the photosynthesis are as follows:

→ Plants take sunlight directly from the sun.

→ Chlorophyll then converts carbon dioxide and water into Glucose, Oxygen and Water.

→ Plants then release oxygen into the air and absorb Glucose and also absorb water but evaporates excess water.
