Lab #7 Seedless Vascular Plants Introduction In today’s lab, we will study seedless vascular plants. This plant group evolved by the late Devonian period and was the prominent group during the Carboniferous period of the Paleozoic era. They formed the first forests about 385 million years ago. These forests are the main source of fossil fuels we use today. Critical innovations that lead to the success of seedless vascular plants were the vascular tissue and wind-blown spores. The vascula...

Parenchyma cells - Play a role in storage, secrection, and photosynthesis in cells. Have thin and flexible primary walls, large central vacuole, lack secondary walls, photosynthesize Ground Tissue - Tissue system that makes up the majority of a plant What is ground tissue composed of? - Parenchyma, collenchyma, sclerenchyma Collenchyma cells - Provide flexible and mechanical support; found in stems and leaves, used for new plants. Lacking secondary walls. Strings on a celery stalk Sclerenc...

Exam (elaborations) BIOLOGY 1307 Lab Assignment #6 - Seedless Nonvascular Plants Bio. 2 Lab Manual: Part 2 – Plants Introduction to Plants The purpose of this lab unit is to introduce students to the fundamental components of plant evolution. Students will begin with the most primitive land plants – seedless non-vascular plants – and work their way up to the most advanced and dominant form of plant life on Earth – the angiosperms. Over the next couple of labs, you will study the various...

Coevolution adaptations go hand in hand, with one species evolving with the other Plant/Animal Hierarchy Cells --> Tissues --> Organs 3 Plant Tissues 1. Dermal ("Skin") 2. Vascular ("Veins") 3. Ground Tissue ("support tissue") Leaves Responsible for collection and conservation of solar energy Main photosynthetic organ of most vascular plant Stems Positioning and support of leaves Trunks of trees are actually modified stems Roots Anchorage and absorptionVery important for gas...
