Heterotrophic Nutrition In Plants

Plants can make their own food therefore plants are autotrophic. Whereas animals cannot make their food, and dependent on plants to derive nutrition, hence animals are known as heterotrophs. But the question arises if all plants are autotrophic?

The mystery of different colours of plants

We have generally seen that flowers are mostly liked by people. We admire their beauty, the fragrance and especially the perfect blend of colours that make them so much mesmerizing that it can attract the pollinators. This article tries to reveal the mystery of different plant colours.
