ADAPTATIONS FOR LIVING ON LAND KEY- TO SURVIVE ON LAND, PLANTS MUST HAVE STRUCTURES THAT ALLOW THEM TO OBTAIN H2O AND OTHER NUTRIENTS FROM THEIR SURROUNDINGS, RETAIN H2O. KEY-THEY MUST ALSO BE ABLE TO TRANSPORT MATERIALS IN THEIR BODIES, SUPPORT THEIR BODIES, AND REPRODUCE.
SKETCH- Plant transport and support
ADAPTATIONS CONT’D CUTICLE- IS THE WAXY H2O PROOF LAYER THAT HELPS PLANTS REDUCE H20 LOSS. VASCULAR TISSUE- CONSISTS OF TUBE-LIKE STRUCTURES INSIDE A PLANT THROUGH WHICH H20, MINERALS, AND FOOD MOVE.
Classification of plants Key- scientist informally group plants into two major groups- 1. nonvascular plants 2. vascular plants. Nonvascular plants- low growing, lacking a well developed system for transporting water and other materials. Moist/ damp environments' Ex- moss

Vascular plants Vascular plants- Better suited for life on dry land. Well developed vascular tissue to transport h2o and other materials, quickly and efficiently. KEY- THEY Can grow tall, covers most plants and trees there are 3 main types 1. Seedless vascular plants- reproduce by making spores. Ex- ferns
Vascular cont’d 2. Gymnosperms- are vascular plants that reproduce by seeds they do not form flowers or fruits. Ex- pine trees 3. Angiosperms- are vascular plants that flower, and produce seeds that are surrounded by fruit. Ex- cactus, wheat,

SKETCH IN NOTES
Life cycle Key- plants have complex life cycles that include 2 stages the sporophyte stage and the gametophyte stage. Sporophyte- the plants produces spores, tiny cells that can grow into new organisms. Gametophyte- plants produce sex cells, or gametes. The two types are sperm and egg cells.
