Six fundamental characteristics of plants | Britannica
The plant kingdom consists of multicellular eukaryotic life-forms ( see eukaryote) with six fundamental characteristics: photosynthesis as the almost exclusive mode of nutrition, essentially unlimited growth at meristems, cells that contain cellulose in their walls and are therefore somewhat rigid, the absence of organs of movement, the absence ...
1.1: Plants, Botany, and Kingdoms
Minot State University. Botany is the scientific study of plants and plant-like organisms. It helps us understand why plants are so vitally important to the world. Plants start the majority of food and energy chains, they provide us with oxygen, food and medicine. Plants can be divided into two groups: plants 1 1 and plants 2 2.
Plant
Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to make their own food. There are over 300,000 species of plants; common examples of plants include grasses, trees, and shrubs. Plants have an important role in the world's ecosystems.

What is a plant? — Science Learning Hub
Plants are photosynthetic and contain a green pigment called chlorophyll, which enables plants to convert energy from the sun into food. Plants store their food as starch. Most plants are rooted to one place – some plants can orientate leaves towards the sun and some respond to touch. Plant cell walls are rigid as they're made of cellulose.

Plant
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll.
