Basic Plant A & P
What are my learning targets?
Identify the basic plant organs and their functions.
List the 3 tissue types of plants and the general function of each.
Name the substances that flow through the xylem and those that flow through the phloem.
ROOTS
Name and describe 3 basic functions of roots.
What are the three basic types of roots? Can you identify them?
Describe how water moves from roots to stems to leaves.
Identify 3 factors which will effect transpiration.
Identify and describe the structure/function of the epidermis, pericycle, cortex, endodermis, xylem, and phloem in roots.
STEMS
Name and describe 3 functions of a stem.
What are some of the structures located on the outside of a stem?
What are the major structures inside a stem? What is their function?
Compare and contrast 5 different types of specialized stems?
LEAVES:
Name 5 classes of plant hormones and the general effect they have on plants.
How am I going to learn them?
How will I know I learned them?
Notes/Visuals-
Plants Dissassembled Lab- See Georgia Organic curriculum lab, students will disassemble weeds, greenhouse crops, and school yard plants to determine the function of each of the major parts in their own words. After that, the students will compare what they infer with the presentation visuals/notes.
Xylem and Phloem Lab- Observing preepared slides to identify xylem and phloem and then preparing slides to see them in action.
Practice- Plant parts coloring diagram, hormone wkst, vascular tissue wkst plant parts powerpoint, see OGC.
Notes/visuals
lk
Root Lab- students will observe and identify different parts of roots. They will infer the function of each part and connect those findings to the actual functions within the visuals/notes. Each group will observe prepared slides as well as preparing their own slides.
Root coloring diagram- see botany coloring book
Order prepared slides!
Visuals/Notes
Celery Experiment- Stems of plants are important because they transport water and nutrients throughout the plant. The following activity will show students how the stems move water up the plant. See accompanying ppt/wksts(CAAG) The exercise will also include observing different stem types, sketching them, and labeling their parts.
Stem coloring diagram/memory game
Evidence of Transpiration Lab- Students will use plastic bags to cover plants. The lab begins with observing and identifying guard cells and stoma from prepared slides. They will look for evidence of transpiration and infer how it happens/why its important/factors that may influence the rate of transpiration. See accompanying ppt/wksts (CAAG).
Dendrochronology study- Linking climatic history to growth in tree (rings of xylem). See lab sheet and tree ring climatogram study.
Stem Study- Students will identify the terminal bud, bud scales, lateral bud, leaf scar, node, and lenticels on a woody stem (dicot stem).
Plant Hormone wkst
Plant hormone jigsaw- students will research one hormone, generate a visual display of their influence, and make connections to the growth in the greenhouse.
Look for good plant hormone studies.
