• 1. Plant molecular biology — Study the structures and functions of important biological molecules such as proteins and nucleic acids.
• 1. Plant biochemistry — study of the chemical interactions within plants, including the variety of chemicals that plants produce.
• 1. Plant cell biology — Encompasses the structures, functions, and life processes of plant cells
• 1. Plant anatomy — microscopic plant structure (cells and tissues)
• 1. Plant morphology — refers to the structures of plant parts such as leaves, roots, and stems, including their evolution and development.
• 1. Plant physiology — study such processes as photosynthesis and mineral nutrition to understand how plants function.
• 1. Plant genetics — study heredity and variation.
• 1. Plant ecology — the study of the interrelationships among plants and between plants and their environment.
• 1. Plant systematics — encompasses the evolutionary relationships among different plant groups.
• 1. Plant taxonomy — a subdiscipline of systematics- deals with plant description, naming, and classification.
• 1. Paleobotany — is the study of the biology and the evolution of plants in the geologic past.
• Most important plant parts used for food…

  • Seeds are found in cereals, grains, legumes & nuts.
  • Fruits and seeds
• Next important plant parts used for food…

  • Root crops and leaves
• • Plants as primary source of food since the development of agriculture 10,000 years ago.
• Plants release oxygen, and uses carbon dioxide released by humans & other heterotrophs.
• what

  A) 10 pounds

  A) trapping

  B) washes

  
• Light emitted from the sun also contributes to the heating of the atmosphere. Where plants are present on the earth’s surface, the solar radiation is mostly absorbed by the plants, reducing the amount of heat reflected into the surrounding air.
• Phytoextraction — the use of plants to remove contaminants from soils.
• • Phytovolatilization —  involves the uptake of contaminants by plant roots and its conversion to a gaseous state, and release into the atmosphere
• Rhizostabilization refers to the process by which plant roots stabilize and improve the quality of soil
• • Rhizofiltration is a water treatment process that involves the use of plant roots to remove or detoxify contaminants from water
