• Question: What words come to mind when you hear the word plant?

• Individually- list a min. of 20 words associated with plants (5 foods max.)

• Pairs- eliminate duplicates and get list back up to a min. of 20.

NOTES ON 20TH CENTURY MED MAN. (video in library) • Botany

• Ethnobotany• Dr. Mark Plotkin (Harvard)• Jaguar Shaman• 25% of modern meds have their origin in plants• examples poppy (opium, morphine)

periwinkle (vincristine) willow (aspirin)• Info lost about plants b/c

– Young people are uninterested in learning– Extermination of tribes – Loss of rain forest– Death of knowledgeable elders

C. HUMAN EXISTENCE 200,000 TO 100,000 humans in an

early forms; H. sapiens var. sapiens and H. sapiens var. neaderthalensis

• 25,000 to 35,000 years ago substantial archeological and fossil evidence of ONLY H. sapiens var. sapiens (us)

EARLY HUMAN LIFESTYLE?• Hunter/gatherer

• Man herd food season

• Change in human behavior approximately 9,000 years ago

• Domestication/agriculture develops simultaneously in several places in the world

GOOD EVIDENCE OF FARMING

• 7,000 B.C. Fertile Crescent, Near East Wheat , Barley

• " Thailand bean and pea• 5,000 Asia rice• 7,000-5,000 Mexico near Texas

gourds, chili, beans• 5,000 Mexico City squash, beans,

avacado, Maize

Current foods in an area reflect heritage

Brain Storming Activity

• Purpose: Problem Solving, Cooperative Learning

• Question: What plants would you take if you left your home for a destination with unknown resources?

“Canoe Plants”

• Here’s what the people who first settled Hawaii brought with them.

• Video link will be linked here of Brian T. Yamamoto describing Hawaiian “Canoe Plants”

• Insert image of canoe from classroom

• Individually- list a min. of 20 plants essential for survival

• Pairs- eliminate duplicates and get list back up to a min. of 20.

• Group- eliminate duplicates and get back to a min. of 20

• Whole Class: Compile total list and reduce to 20

• Group with the most “ ? “ plants gets a prize

HOMEWORK• 1. 3 DAY RECALL OF YOUR CONTACT WITH

PLANTS• 2. AT LEAST 10 PLANTS PER DAY MUST BE

RECORDED• 3. BE READY FOR ME TO COLLECT THEM AT

ANY TIME• 4. 10 PTS.

Anti-Bacterial properties of Spices

• Hope to improve my bacteria unit by expanding the use of spices in our LAB on bacteria culturing and growth inhibition

D. PLANT ANATOMYPart II of PlantsRead 569-582

I. GROSS ANATOMY

• ROOTS (functions?)– Anchor– absorb water and

nutrients– asexual reproduction

(ex. Raspberry)– storage ex. Yam,

carrot , beet

LEAVES– Photosynthesis

– Enzymes, sunlight, chlorophyll– Transpiration – release of water through the

leaf surface. The plant is like a straw. Roots have the opening and the leaves have the exit

– asexual reproduction ex. African violet Kalanchoe

– storage ex. Cabbage, onion, lettuce

STEM FUNCTIONS CONTINUED

STEM (functions?)support the leaves and

flowersasexual reproduction

ex. Potato, strawberrystorage ex. Potato,

broccoli, cauliflower , asparagus

II. CELLULAR ANATOMY

• transport• xylem• phloem• dividing region• absorption

• Water up• Sugars down• Meristem• Root tip

• support- wood• dating activity with

growth rings

How old is this stem?

12 years old

Photosynthesis

• leaf anatomy- stomata

• from work sheet• chromatography- pigments

• chlorophyll• carotene• xanthophylls

III. PLANT RESPONSES (tropisms)

• Controlled by hormones that stimulate specific cells to grow

• Thigmo tropism• Phototropism• Gravitropism• chemotropism

cell divisionAdding to

length at root and stem tips by apical meristem

cell division

Adding to the width-lateral meristem

Vascular bundleLooks vaguely like

an ice cream cone

Cell division – where the cells are reproducing

• root and stem tips apical meristem• width- lateral meristem

Photosynthesis

1. Leaf Anatomy – stomata and guard cells (from worksheet)

2. Chromatography- pigment mixtures are separated and analyzed

• Chlorophyll – green pigment• Carotene – orange pigment• XanthophyllsXanthophylls – yellow pigment

III. PLANT RESPONSES (tropisms)

• Controlled by hormones that stimulate specific cells to grow

• Thigmotropism – response to touch (vines, venus fly traps)

• Phototropism – response to light (seedlings)• Gravitropism – up and down growth• Chemotropism – response to a chemical

stimulus (ex. fertilizer)

Thigmotropism

• The turning or bending response of an organism upon direct contact with a solid surface or object.

Phototropism

Gravitropism

Chemotropism

• Growth towards water or fertilizer (sewage line)

Legumes

• Simple dry fruit • Common name for fruit is a pod• Peas, beans, lentils, and peanuts• High in protein
