|
Fern
|
|
The Gametophyte is these two plants are dominant and photosynthetic. Male and female gametes are produced on the same plant. They need H2o for reproduction.
|
Mosses & Ferns
|
|
This plant has large, dominant Sporophyte BUT it's Gametophyte is independent. It needs H2o and it's gametes are on the same plant.
|
Fern
|
|
In these plants, the Gametophyte is microscopic and dependent. Male and female are separated. Water is not needed for fertilization. They produced seeds and have large, dominant Sprophytes.

Flowering plants ( Angiospermae)
|
- Tracheophyta
- Pollen tube carries sperm - Contain Xylem & Phloem - Contains roots, stems & leaves - Sporophyte dominant - Has flowers & seeds - Wide spread areas |
|

Three features that distinguish all vascular plants
[**********] |
- Xylem
- Phloem - !!!!!!!!!!!!!!!!! |
|
Plant adaptations that allowed early land plants to reproduce without H2o
|
- cones
- seeds - pollen - flowers |

|
|
Monocots
|

Dicots
|
- Two cotyledons
- Branced veins - Floral parts in multiples of 4 & 5 - Vascular bundles in a ring - Taproot |
|
Xylem
|
- vascular tissue that carries H2o upward from the roots to every part of the plant
