How do green plants obtain their food?

Green plants obtain their food through a process called photosynthesis. Here's how it works:

1. Sunlight: Plants capture light energy from the sun using a green pigment called chlorophyll. Chlorophyll is found in organelles called chloroplasts within plant cells.

2. Carbon Dioxide: Plants take in carbon dioxide from the air through tiny pores on their leaves called stomata.

3. Water: Plants absorb water from the soil through their roots.

4. Chemical Reaction: Inside the chloroplasts, the captured light energy is used to convert carbon dioxide and water into glucose (sugar), which is the plant's food source. This process also releases oxygen as a byproduct.

The chemical equation for photosynthesis is:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

* CO2: Carbon dioxide

* H2O: Water

* C6H12O6: Glucose (sugar)

* O2: Oxygen

In short, green plants use sunlight, carbon dioxide, and water to produce their own food (glucose) through photosynthesis. This makes them autotrophs, meaning they can make their own food.
