Intro to Seed Plants

• Seeded vascular plants are no longer reliant on?

  Water
• There are 2 groups of seeded vascular plants:

  Gymnosperms and Angiosperms
• The ____ generation is the dominant generation

  Sporophyte(2n)
• Seeded plants became dependent on the ____ due to the ____ of the gametophyte (n) generation

  1.) Sporophyte (2n)

  2.) Reduction
• Key evolutionary adaptations in seeded vascular plants:

  Having Pollen and Seeds
• Microspores in Seeded Vascular plants are:

  The male gametophyte -> Pollen
• Megaspores in Seeded Vascular plants are:

  The female gametophyte -> Embryo sac
• Gymnosperms have gametophytes that develop inside of:

  Cones (ex: pine cones)
• Angiosperms have gametophytes inside of:

  Flowers
• In Seedless Vascular plants:

  the sporophyte is dependent at first while the gametophyte is independent
• What is pollination?


  Pollination is the transfer of pollen to the part of the plant that contains the ovule
• Each seed is a ____

  Mature Ovule
• A seed contains tissues from 3 generations of plants:

  1.)The Seed Coat from mature sporophyte

  2.) The Food Supply from female gametophyte

  3.) The New Embryo is the new sporophyte gen.
• Seeds are ____ , ____, can remain ____, and has its own ____

  1.) Protected

  2.) capable of Dispersal

  3.) Dormant

  4.)Food Supply
• Gymnosperms are often called:

  "Naked Seeds" from not being enclosed in a protective covering
• Male/Female reproductive organs form in ____

  Cones
• What is the difference Monoecious vs Dioecious?

  Monoecious: Both male and female reproductive structures are found on the same individual.

  Dioecious: Male and female reproductive structures are found on separate individuals.
