Biology 4th Block Room 128 Mr. R. Bair Biology Teacher Mrs. MV Smith Resource Teacher Date: May12, 2008 Drill Biology 4th Block Room 128 Mr. R. Bair Biology Teacher Mrs. MV Smith Resource Teacher Way they reproduce Do they have vascular tissue? No Developing vascular tissue No support because no vascular tissue size Examples Other facts Small & low to the ground No vascular support -mosses -liverworts -hornworts Bryophytes -No roots, stems, or leaves, -pioneer species -prevent erosion Non vascular plants Bryophytes -with water sperm to swim to egg Seedless vascular plants Pterophyta Need water Spores under leaves Groups of spores is called a sori yes Not real large but bigger than non-vascular Still under a few feet -Ferns -clubmosses horse tails wisks ferns Pterophyte Shoots & roots Underground stem Rhizome -first vascular plants Way they reproduce Do they have vascular tissue? Yes size Examples Other facts Anywhere from a brush to a large tree evergreens -Pine -Cedar -spruce -fir -holly -conifirs softwood grow fast “naked seed” no fruit first seed plants -needles for leaves yes Anywhere from grass to large trees Small bushes Flowers trees Flowering plants Trees Normal plants Monocot: o Corn o Grasses o Lillies o Orchids o Palms Dicot o Maple o daisy o Cucumber o beans Insects help pollination Gymnosperms Evergreens -Seeds embryo & food source -cones (male & female) pollen cone & seed cone Angiosperms Flower Pistil Stamen Anther Pollen Seed Fruit flowers -Monocot (parallel veins) one seed leaf Dicot (net Veins) apple, lettuce, oak 2 sead leafs not veination Biology 4th Block Room 128 Mr. R. Bair Biology Teacher Mrs. MV Smith Resource Teacher Petals- The petals (which are usually bright or bold in color) are the part of the flower that usually catch our eye when we first look at it. They catch bees' eyes, too! They are what attract the bees to the flower. Sepals- Parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens Pistil- The pistil is the female part of the flower. It includes the stigma, the style, the ovary, and the ovules stigma- the tip of the pistil that receives male pollen grains style- the long stalk that the stigma sits on top of ovary- has the seeds inside and turns into the fruit that we eat ovules- the part of the ovary that becomes the seed Stamen- The stamen is the male part of the flower. It is made up of the anther and the filament. anther- yellow, pouch-like part inside of the flower that holds pollen grains. It is usually on top of a long stalk that looks like a fine hair filament- This is the fine hair-like stalk that the anther sits on top of. Lab Test on plants
