What is a sporophyte?

What is a gametophyte?
A gametophyte is something a sexual unit of reproduction. ie: sperm and egg
What is fertilization?
sperm cell fuses with the egg cells
What are the two types of adult generations?
gameteophytes and sporophytes
What happens during the sporophyte generation?
The spores are created
What happens after the adult sporophyte generation?
The spores travel through the air and land in soil.
WHat happens after the spores travel?
The gametophyte generation.
What happens during the gametophyte generation?
The spores are turned into gametes.
What happens after the gametophyte generation?
The egg is fetilized by the sperm.
What occurs from fertilization?
seeds in higher plants or adult sporophytes in lower plants
Do all plants have seeds?

What are three qualities of the Phylum Tracheophyta?
1. sporophyte generation is dominant
2. Roots, stems, and leaves
3. xylem and phloem

What is xylem?
system of transport for water
What is phloem?
transports food down to the root, toward hell.

As plants get bigger, they need a more effective transportation system.
