Review: Why do cells need active transport? Why can't they rely on osmosis and diffusion to obtain the molecules they need?
EQ: Which plant cells use active transport to move molecules? What kinds of activities do plant cells perform?
Activity: Observe the images in the plant presentation. Make a term list for each section in your science notebook:
Class #3 Term List
flowers
vegetables
reproduction
pollination
pollen
Class #4 Term List
fruit type
seed
nut
Class #1 Term List
fruit
leaves
stems
Class #2 Term List
anther
stamen
stigma
pistil
Analyze the function of different types of plant cells using one of the web resources below:
E-flora- Meet the Plant Parts - build a salad, presented by Howard Hughes Medical Institute
- Photosynthesis, Energy and Life - an elementary school science site
- Science 4 Kids - from USDA (click on parts of the large picture!)
- Plant Watch - part of Canada's Nature Watch citizen science programs
- The Great Plant Escape - a clever chapter for 4th and 5th graders, 6 activities and a teacher's guide
- The Science of Gardening - from the Exploratorium
- US Department of Agriculture for Kids
- Young Naturalist's Page - a focus on plants of Florida
Illustrate 2 of the plant diagrams that you locate online, with arrows and labels to show where molecules would move in and around the plant cells:
| Plant #1 | Plant #2 |
