- What are the 11 plants that produce 95% of the world's food supply?
- Seed coat
- When sepals and petals are identical (ex: gladiola)
Sepals are on the outside; petals are on the inside.
- a ripened ovule
- a ripened ovary
- Structures inside the ovary that develop into seeds. Each ovule can produce only one seed.
- a young plant that develops from a zygote
- Single 2n cell formed by fertilization. When it divides, it becomes an embryo. A fertilized egg.
- Union of the egg and sperm
- female gamete (1n)
- male gamete (1n)
- the process whereby pollen transfers from stamens to the pistil
- Accessory fruit
- fruit that develops from the ovary and some other associated part (apples)
- Inferior ovary
- when the pistil is embedded in the receptacle
- True fruit
- develops only from the ovary (plums, cherries)
- Superior ovary
- when the pistil is resting on top of the receptacle
- Complete flower
- Has all four whorls
- Perfect flower
- One with stamens and pistils
- the passive intake of water that allows seeds to enlarge
- Imperfect flower
- one that lacks either male or female parts; has a whorl missing (has either stamens or pistils)
- transition zone
("the part of the axis of a plant embryo or seedling below the cotyledon")
- (epicotyl) first bud or shoot of plant
("the primary bud of a plant embryo usually situated at the apex of the hypocotyl and consisting of leaves and an epicotyl")
- Filth level of whole pepper
- 1% mammalian excreta per pound on average
