Plants Introduction

-Monocot and Dicot Coloring Agenda: -Bellringer -Propagation Lab -plant type notes -Monocot and Dicot Coloring Bellringer Briefly tell the function of the 3 parts of the plant cell that are unique to the plant cell. Are plant cells eukaryotic or prokaryotic? Explain how you know this

Propagation Lab Make sure the date is written next to your first drawing Measure your stem Record surface area of ALL leaves! Count a partial square if it is at least half covered by the leaf; do not count partial squares that are less than half covered.

Objective You will be able to name and provide characteristics of the 4 plants groups You will be able to explain the difference between monocots and dicots

Plants!! Botany = the study of plants!

Overview of Plant Kingdom Botanists divide the plant kingdom into four groups Flowering plants (angiosperms) Cone bearing plants (Gymnosperms) Ferns and relatives (seedless vascular plants) Mosses and relatives (Bryophytes) Based on 3 factors: Water-conducting tissues Seeds Flowers Today plant scientists can classify plants more precisely by comparing the DNA sequences of species.

Bryophytes Low growing plants found in moist, shaded areas. Lack vascular tissue, therefore these plants use osmosis to draw water up a few centimeters above ground. 3 groups Mosses Liverworts Hornworts

Seedless Vascular Plants Have true roots, stems, and leaves. Have specialized tissue that transports water and sugar. 3 groups Horsetails Club mosses ferns

Gymnosperms Conifers (Christmas trees!) “naked seeds”- cone bearing plants (seeds grow on cones) Needle like leaves Usually stay green year around Wind pollinated Examples: pine trees and evergreens!

Angiosperms Flowering plants Seeds are enclosed in a fruit Most are pollinated by birds and bees Have finite growing season Examples: grasses, tulips, oaks, and dandelions

Angiosperms are divided into two main groups: http://www.youtube.com/watch?v=gI2RxzAT-ww

Dicots:

Monocots:

Parts of the Plant Roots/ Stems/ Leaves Roots: -Water and minerals are absorbed Also used to anchor the plant

Stems Transports water and nutrients Support plant *Two types: herbaceous and woody

Leaves Photosynthetic organ of the pant, used to convert sunlight into food! Photosynthesis: Carbon dioxide + water = Sugar + oxygen
