Green plants are :

Options

A. autotrophs
B. heterotrops
C. parasites
D. saprophytes

Answer

**Step-by-Step Solution:**

1. **Understanding Green Plants**: Green plants are organisms that contain chlorophyll, the green pigment responsible for photosynthesis.

2. **Photosynthesis Process**: During photosynthesis, green plants use sunlight to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. This process is crucial as it allows plants to produce their own food.

3. **Definition of Autotrophs**: Autotrophs are organisms that can produce their own food from inorganic substances. Since green plants can make their own food through photosynthesis, they are classified as autotrophs.

4. **Understanding Other Options**:
- **Heterotrophs**: These are organisms that cannot produce their own food and depend on other organisms for nutrition. This option is incorrect for green plants.
- **Parasites**: These organisms live on or in a host and derive nutrients at the host's expense. Green plants do not fit this category.
- **Saprophytes**: These organisms feed on dead and decaying organic matter. Green plants do not belong to this group either.

5. **Conclusion**: Based on the definitions and characteristics discussed, the correct classification for green plants is that they are autotrophs.

**Final Answer**: Green plants are autotrophs.
