Plant

A plant is a eukaryotic organism whose cells typically have cellulose walls and whose members include photosynthetic land plants and diverse algae. Land plants generally make sugars using light, water, and carbon dioxide.

Connect

Plant cell: A eukaryotic cell with a cellulose-rich wall, usually containing chloroplasts and a large central vacuole. Its wall, vacuole, and chloroplasts distinguish plant structure from animal cells.
Photosynthesis: A process that converts light energy into chemical energy, usually using carbon dioxide and water to produce carbohydrates and oxygen. It explains how most plants build sugars from inorganic materials.
Archaeplastida: A eukaryotic group that includes land plants, red algae, and green algae. Land plants belong to this broader lineage of photosynthetic eukaryotes.
Agriculture: The cultivation of plants and rearing of animals to produce food, materials, and other useful goods. Cultivated plants supply a large share of human food and raw materials.
Fungus: A eukaryotic organism that absorbs nutrients from its surroundings and typically has chitin in its cell walls. Fungi have cell walls but generally obtain food by absorption rather than photosynthesis.
Chloroplast: An organelle where photosynthesis converts light energy into chemical energy. Chloroplasts carry out the light-driven reactions that support plant growth.
Xylem: Vascular tissue that conducts water and dissolved minerals from roots toward the rest of a plant. Xylem supplies leaves and other tissues with water for photosynthesis.
Charophyte: A group of green algae closely related to land plants. Charophytes share traits that illuminate the ancestry of land plants.
Crop rotation: The planned succession of different crops on the same land across growing seasons. Rotating plant families can manage soil nutrients, pests, and diseases.
Animal: A multicellular eukaryote that obtains nutrients by consuming other organisms or organic matter. Animals lack cell walls and do not typically make food through photosynthesis.
