Why are green algae considered as ancestors of land plants?

Explanation

**Step-by-Step Solution:**

1. **Introduction to Green Algae and Land Plants:**
- Green algae are simple, aquatic organisms that belong to the group of protists. They are primarily found in freshwater environments, but some can also be found in marine and terrestrial habitats.

2. **Presence of Chlorophyll:**
- Both green algae and land plants contain chlorophyll, the green pigment responsible for photosynthesis. This pigment allows them to capture sunlight and convert it into energy, which is a fundamental process for both groups.
