    Cannabis: scientific name for marijuana specifying genus
    capitate stalked trichome: resin-producing plant hair without a stalk, high in THC content
    carbohydrate: neutral compound of carbon, hydrogen, and oxygen, mostly formed by green plants: Sugar, starch, and cellulose are carbohydrates.

Callus
    carbon dioxide (CO 2 ): a colorless, odorless, tasteless gas in the air; necessary for plant life
    caustic: a substance that destroys, kills, or eats away by chemical activity
    CBD: cannabidiol: CBD usually prolongs the high.

Outdoor Plant

Indoor Plant
    cell: the base structural unit of plants: cells contain a nucleus, membrane, and chloroplasts
    cellulose: a complex carbohydrate that stiffens a plant: Outdoor stems contain more stiff cellulose than plants grown indoors.
