Plants are living things that grow in different places called habitats (ఆవాసాలు). Based on where they grow, plants are mainly of two types: terrestrial (నేల పై పెరిగే) plants and aquatic (నీటిలో పెరిగే) plants. Terrestrial plants grow on land, such as trees, shrubs (పొదలు), herbs (గుల్మాలు), and climbers (ఎగబాకే మొక్కలు). Examples include mango trees, rose plants and grass. Aquatic plants grow in water, like ponds, lakes, and rivers. Lotus, water lily and hydrilla are aquatic plants. Different plants have special features (ప్రత్యేక లక్షణాలు) that help them survive in their habitats.
