növényt

Növény is the Hungarian word for plant. In biology, a plant is any member of the kingdom Plantae. This kingdom comprises terrestrial plants, as well as the marine algae and some flagellates. Plants form a major group of living organisms. They are multicellular eukaryotes, typically possessing cell walls made of cellulose and obtaining most of their energy through photosynthesis. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigment.

The plant kingdom is incredibly diverse, ranging from tiny mosses and ferns to giant trees. They play a crucial role in ecosystems, producing oxygen, providing food and shelter for other organisms, and influencing soil composition and water cycles. Their life cycles often involve alternation of generations, with distinct haploid and diploid phases. Reproduction can be sexual, involving the fusion of gametes, or asexual, through methods like vegetative propagation.

Humans have a long and complex relationship with plants. They are a primary source of food, medicine, building materials, and fuel. The study of plants is known as botany. Classification within the plant kingdom has evolved over time, with modern systems based on genetic and evolutionary relationships. Understanding plants is fundamental to many scientific disciplines, including ecology, agriculture, and conservation.
