General Traits
•Multicellular, eukaryotes•Makes its own food, glucose,
by photosynthesis in chloroplasts• Cell walls made of cellulose

Major Phyla
• Bryophytes (Mosses)• Ferns• Gymnosperms (cone-bearing
plants)• Angiosperms (flowering plants)

Major Habitats
Plants have evolved to live life on land, and will live anywhere there is enough sunlight to support photosynthesis.

Transport (move materials)
• Plants move materials through their bodies (roots stem leaves and vice versa) through vascular tubes called xylem and phloem or simple diffusion. • Materials include water, glucose, and
nutrients from the soil.

Excretion (waste removal)
• Plants use holes in the bottom of their leaves, called stomata, to allow excess water to leave the plant. This process called transpiration allows more water to enter the plant at the root.
• These holes are opened and closed by guard cells to prevent too much water loss. A thick waxy layer called the cuticle covers leaves and also prevents water loss.

Respiration (gas exchange)
Stomata and guard cells also allow for the exchange of carbon dioxide and oxygen for photosynthesis and cellular respiration. Otherwise it is simple diffusion.

Nutrition (obtains food)/Niche
Plants are producers (autotrophs) by making glucose through photosynthesis in the chloroplasts. Usually done in the leaf of a plant.

Basic Needs
• Water for photosynthesis and movement of materials from soil through roots.
• Carbon dioxide for photosyntheis from air through stomata.
• Sunlight for photosyntheis through leaves.• Nitrates, phosphorous, and other minerals to
support life from soil through roots.

Types of PlantsVascular-tubes to move materials
Nonvascular-no tubes to move materials
Ferns--Seedless
Gymnosperms—naked seeds, cone bearing
Angiosperms—flowering with seeds in fruit
Bryophyta—no leaves, stems or roots
Moncots—one seed leaf, vascular bundles are parallel in the leaf and scattered in the stem, and flower parts are in multiples of 3.
Dicots—two seed leaves, vascular bundles are netlike in the leaf and in a ring in the stem, and flower parts are in multiples of 4 and 5.
