Plants Introduction
BellringerBellringer1. Briefly tell the function of the 3 parts of
the plant cell that are unique to the plant cell.
2. Are plant cells eukaryotic or prokaryotic? Explain how you know this
Please sit with your previously assigned group
members.Thanks
ObjectiveObjective• 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
PreAssessment
• Go to quizstar.4teachers.org
• Take Plants Test
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:o Water-conducting tissueso Seedso 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=gI2RxzA

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
