Plants

• Leaves: take in air and use light to make food
• 
  
• Stems: hold the leaves up to sunlight and move water, nutrients, and food through the plant
• 
  
• Roots: hold the plant in the soil. They take in water and minerals from the soil
• 
  
• Pollination: The transfer of pollen from the stamens to the pistil
• 
  
• Fertilization: The joining eggs cells and sperm cells
• 
  
• Spore-producing: plants have cones instead of flowers. Spore-producing plants include moss and ferns
• 
  
• Pistil: long tube that grows eggs (female cells) in the ovary. 
• 
  
• Stigma: sticky part of the pistil
• 
  
• Stamen: produces pollen (male cells)
• 
  
• Petals: colorful leaves that attract insect
• 
  
• Sepals: small leaves that cover the flower bud
• 
  
• Vein: a vascular structure on the blade part of a leaf that transports food and water necessary for photosynthesis
• 
  
• Spore: one-celled, reproductive unit capable of lower plants, fungi, and protozoans
• 
  
• Ovary: a female cell reproductive organ in which ova or eggs are produced
• 
  
• Ovule: the part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed
• 
  
• Embryo: the part of a seed that develops into a plant, consisting (in the mature embryo of a higher plant) of a plumule, a radicle, and one or two cotyledons
• 
  
• Seed: a flowering plant's unit of reproduction, capable of developing into another such plant
• 
  
• Pollen: a fine powdery substance, typically yellow, consisting of microscopic grains discharged from the male part of a flower
• 
  
• Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
• 
  
• Germination: the process by which a plant grows from a seed
• 
  
• Chlorophyll: a green pigment, present in all green plants responsible for the absorption of light to provide energy for photosynthesis
• 
  
• Dormancy:  Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped
• 
  
• Carbon dioxide: a colorless, odorless gas produced by burning carbon and organic compounds and by respiration
• 
  
• Oxygen: a colorless, odorless reactive gas. Oxygen forms about 20 percent of the earth's atmosphere, and is the most abundant element in the earth's crust, mainly in the form of oxides, silicates, and carbonates.
