Seeds and their advantages

1) Seed plants don’t depend on water to reproduce– Pollen (contains

sperm) carried by wind/animals

2) Embryo has…– Nourishment: Nutrients

inside feed embryo– Protection: Hard shell

3) Allow dispersal– Carried by wind, water,

animals

Some seeds have “wings”

Some seeds are “dispersed” by

animals

Conifers• Type of gymnosperm• Needle-like leaves (reduces

water loss)• Common to lumber industry• Cones used to reproduce

– Male pollen cones: produce pollen

– Female seed cones: produce eggs

• Embryo grows inside seed• Ex: Evergreen, Pine,

Redwood, Cedar

Page 13: Gymnosperms Group 3: Seed producing, Vascular Plants A)Gymnosperms Seeds not covered by fruit.

Conifer Life Cycle• Mature Sporophyte creates

cones:• Pollen cones (male)

– Microspores created by meiosis– Microspores develop into pollen– Pollen = male gametophyte

Pollen cones

Conifer Life Cycle• Mature Sporophyte creates

cones:• Pollen cones (male)

– Microspores created by meiosis– Microspores develop into pollen– Pollen = male gametophyte

• Seed cones (female)– Megaspore created by meiosis– Megaspore grows to become

female gametophyte– Egg inside female gametophyte

Review1) How are angiosperms different from

gymnosperms?2) Name three advantages of seeds.3) Which structure will protect and release

gymnosperm seeds?4) What are male cones called and what do they

produce?5) What are female cones called and what do they

produce?6) What is created when the sperm and egg fuse:

sporophyte or gametophyte?

The Structure of Flowers. Angiosperms – flowering plants whose seeds are enclosed in an ovary, which becomes a fruit Gymnosperms – plants whose seeds.
