The study of plants is botany. Agriculture is growing plants and raising animals for human use. Cultivars are plants selected by people for at least one distinguishing characteristic that sets them apart from other members of their species.[ex: Mcintosh apples, Seedless Grapes] Cereals are grasses that contain edible grains. Root crops are roots or underground stems that are rich in carbohydrates, like potatoes. Legumes are members of the pea family and are mainly beans. A fruit is the part of a flowering plant that contains seeds. Foods derived from other parts of a plant are called vegetables. A nut is a dry, hard fruit that does not split open to release its seed. Spices com from plant parts other than the leaf and are usually tropical. Herbs come from the leaf and can be grown at home. Quinine is a flavoring used to makes tonic water and treat malaria. Fertilizers give plants essential minerals. Pesticides are chemicals that kill undesirable organisms. Plants can be used as medicine. Aspirin is made from the bark of trees. The FDA does not regular plant products that claim to be magically healing. Plants are used for clothing and dyes. Some plants can be used as fuel. Grains can ferment into alcohol and used in gasohol, which is used in cars. Plants are also used ornamentally in gardens and also in peoples homes during Christmastime. Plants have been the inspiration for inventions like Velcro.
27.2 Plants and the Environment
The study between plants and their environment is called plant ecology. Plants provide organisms with inorganic nutrients. Consumers ingest plants at the bottom of the food chain. Pollinators, such as bees, help plants reproduce by carrying their pollen. The majority of plant species form mycorrhizae which are symbiotic relationships between fungi and the roots. This helps the plant absorb nutrients. Plants provide humans with food, clothing, shelter, and many other products. Weeds are undesirable plants that crowd out crops or native plant species. Some plants can cause harm. Many drugs are made from plants, like tobacco, cocaine, opium, and alcohol. People are also poisoned. Hay fever is an allergic reaction that results in sneezing, runny nose, and watering eyes. Many allergies are caused by airborne pollen.
