Welcome

If you would like to read the syllabus for the Life Science or Earth Science, please click on the links to access information such as classroom rules, the grading scale, and topics to be discussed.
One last thing that you might find interesting is a NASA picture of the day. Every picture has a great description of what you are seeing.


Enjoy!

Bring them to class on 4/19/12 (Thurs)
Chapter 17: Plants
Section 1: An Overview of Plants - section 1 quiz

Section 1 review
  • All plant cells are surrounded by a cell wall
  • Many plant cells contain chlorophyll (the ones that carry out photosynthesis)
  • Ancestors of land plants were probably ancient green algae
  • A waxy cuticle helps conserve water
  • Cellulose strengthens cell walls
  • An advantage of plants living on land is more sunlight and more carbon dioxide
  • Waterproof coating protects (and allows plants) seeds and spores help plants reproduce on land  
  • The plant kingdom is divided into 2 groups VASCULAR and NONVASCULAR
  • Vascular tissues transport nutrients

Section 2: Seedless Plants - section 2 quiz

Section 2 review
Ferns
Moss









  • Seedless nonvascular plants include mosses, liverworts, and hornworts
  • They are usually a few cells thick and a few centimeters tall (1-2 inches tall)
  • they produce spores for reproduction (not seeds)
  • Seedless vascular plants include ferns, club mosses, and horsetails
  • Vascular plants can grow taller and live further from water than nonvascular plants
  • Non-vascular plants help build new soil
  • Coal deposits formed from ancient seedless plants that were buried in water and mud before they decayed

Section 3: Seed Plants - section 3 quiz

Section 3 review

    Pumpkin - a dicot
  • Be able to identify a monocot or dicot from a picture
  • Leaves are the organs of a plant where photosynthesis takes place
  • stems support leaves, branches and contain vascular tissues
  • roots absorb water and nutrients from the soil
  • Gymnosperms do not have flowers, do not produce fruit... the seeds are protected by cones
  • Angiosperms produce flowers that develop into fruit with seeds
  • Most animal diets are supported by feeding on angiosperms
  • The part of a seed that is used for food storage is the cotyledon... monocots have 1 cotyledon, dicots have 2 cotyledons 
  • Be able to give an example of a gymnosperm (conifers are the most familiar spruce, fir, redwoods, pines) and an example of an angiosperm (rice, wheat, corn, fruit trees, flowers)
