Vascular Tissue
Plant embryo and food that are encased in a protective coating

Stigma
Pollination
This process is when egg and sperm fuze together to produce a zygote.

Xylem
How can seeds move if they don't have legs?
Seed dispersal: Wind, water, animals.
Outer most circle of floral parts, usually green and enclose the bud before it opens, protecting the flower during development.
Sepals

Annuals
The shift between haploid and diploid phases is known as...
Alternation of generations
