Depending on the presence of flowers, plants are classified into two types namely, flowering plants and non-flowering plants.
1. Flowering plants are the plants which possess flowers and reproduce through seeds. E.g. mango, papaya, guava, etc.
2. Non-flowering plants are the plants which do not use flowers to reproduce. These plants reproduce through spores. E.g. ferns, mosses, etc.
Depending on the mode of nutrition, plants are classified into autotrophic and heterotrophic.
1. Autotrophic plants are the plants which make their own food by the process of photosynthesis by using raw materials like carbon dioxide and water. All green plants exhibit photosynthesis.
2. Heterotrophic plants are the plants which depend on other organisms for their food.
For example, plants like venus flytrap that derive their nourishment from insects are called insectivorous plants.
