The Rise of the Vascular Plants
a.k.a "tracheophytes"
Contain Tracheid cells- hollow tubelike cells found in xylem tissue
Vascular plants have two transport tissues: Xylem (zylum) & Phloem (flohum)
8
The Rise of the Vascular Plants (cont'd)
The role of xylem is to carry water upward from the roots to every part of the plant
Each tracheid cells in these tissue contain a "pit region" which allows water to be transferred from one cell to the next (assembly line)
9
The Rise of the Vascular Plants
The role of phloem is to transport the nutrients & carbohydrates produced by photosynthesis
Vascular tissues allow for plants to move fluids through their bodies against gravity...w/in "limits"
10
The Rise of the Vascular Plants (cont'd)
The evolution of vascular tissue permitted the evolution of roots, tree-sized plants, and allowed plants to spread into dry areas of land

Multiple Choice
Plants that have true roots, stems and leaves are called ____.

What is a seed? To be, or not to be? That is the question!
14
Gymnosperms vs Angiosperms
Gymnosperms= seed-bearing vascular plants whose seeds are exposed to the environment on scales of cones instead of enclosed in a fruit
"Seed- plant embryo & its food supply encased in a protective covering"
Similarities in DNA sequence = seed plants descended from a common ancestor
15
Gymnosperms vs Angiosperms (cont'd)
Angiosperms = plants that bear seeds in a closed ovary (special structure found within the flower)
The great majority of plant species (approx. 260,000)
As seeds mature, ovaries develop into fruits that help to disperse the seeds to new locations
