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.

2017年4月4日 · Plant Definition. 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.

2025年1月16日 · Plant, any multicellular, eukaryotic, usually photosynthetic life-form in the kingdom Plantae. There are an estimated 390,900 different species of plants known to science. Learn more about the plant kingdom, including the life and evolutionary histories and physical characteristics of the major plant groups.

Plants are one of six big groups (kingdoms) of living things. They are autotrophic eukaryotes, which means they have complex cells, and make their own food. Usually, they cannot move (not counting growth). Plants include familiar types such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae.

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 ...

2024年5月14日 · Plants are eukaryotic organisms that are photosynthetic and with a rigid cell wall. Learn the definition of a plant, its structure, taxonomic groups, characteristics, evolution, and ecological importance here.

2016年12月16日 · The study of plants is known as botany and in this introduction to plants we look at key topics such as the process of photosynthesis, different types of plants and the different parts of a plant such as roots, stems and leaves.

2025年1月16日 · Plant - Photosynthesis, Reproduction, Evolution: Plants (kingdom Plantae) are all multicellular and eukaryotic, and most can convert the energy of sunlight into chemical energy by means of photosynthesis; they are autotrophic and store their excess food as starch.

2024年2月5日 · Plants are an essential component of Earth's ecosystems that are considered as living things. They are classified as members of the kingdom Plantae and are distinguished by their capacity to generate food on their own through a process known as photosynthesis.
