Understanding Plants: Terrestrial and Aquatic

The video tutorial explains that plants are living organisms that grow on Earth and are essential for oxygen production through photosynthesis. It categorizes plants into terrestrial and aquatic types based on their growing environment. Terrestrial plants grow on land with roots underground, while aquatic plants grow in water with floating capabilities. Examples include shrubs and mango trees for terrestrial plants, and lotus for aquatic plants.
