Entry Task

Grab a computer & begin working to complete the group portion

of your plant identification activity.

Agenda Housekeeping

Plant Identification Activity

HousekeepingPlant identification due at the end of the period.

Progress reports will be going out Friday, 5 May.

• Get those missing assignments turned in.

Plant IdentificationGroup (due at the end of the period):

• Claim = what plant species.

• Evidence = internet sites with reference.

• Reasoning = Tie the evidence into the claim.

Plant IdentificationClaim, Evidence, & Reasoning:

Claim = The leaf collected came from the Acer palmatum

dissectum 'Viridis‘ (common name Japanese Maple).

Plant IdentificationClaim, Evidence, & Reasoning:

Evidence = According to the Missouri Botanical Garden’s

webpage the tree is described as a deciduous shrub or small

tree that typically grows to 10-25‘ containing palmate green

leaves (2-5" long) having 5 to 7, but less frequently 9 toothed

lobes (http://www.missouribotanicalgarden.org/PlantFinder/

PlantFinderDetails.aspx?taxonid=259409&isprofile=0&).

Reasoning = According to the evidence the leaf description very

closely matches that of the leaf collected. The leaf was obtained

from a small deciduous shrub about 4.5 feet tall. It is a simple

2.25” palmate leaf containing the less frequently observed 9

toothed lobes.

Leaf Structure & Function

HousekeepingProgress reports will be going out Friday, 5 May.


Objective(s)What are the structures & function of leaves?

Leaf StructureAll leaves originate from the stem as leaf primordia (small

cellular outgrowths).

During development leaves take on different forms, shapes, &

sizes depending on the specific function they have to perform.

Four basic type of leaves:

• “Ordinary” or “typical” photosynthetic leaves.

• Bracts or scales

• Tendrils

• Succulent leaves

Leaf Structure“Ordinary” or “typical photosynthetic leaves:

• Flattened leaf blades (lamina).

• Lamina can be undivided (simple) or subdivided (compound).

• Main function is photosynthesis.

Bracts or scales:

• Mostly colorless or brown

• Tough, overlapping, & waterproof

• Protects buds like flower buds, apical buds, & axillary buds.

Leaf StructureTendrils:

• Parts of the leaf transformed into thin threadlike appendage.

• Growing in a spiral form, that stretches out & curls around

support structures to help climb.

Succulent leaves:

• Large, fleshy structures.

• Store water & food.

Leaf StructureComponents of a leaf:

Leaf StructureLeaves are identified using 7 basic structures:

• Shape

• Tips

• Margins

• Bases

• Attachments

• Arrangements

• Habits

Dichotomous Key1. a. Needle leaves go to 2

b. Non-needle leaves go to 3

2. a. Needles are clustered Pine

b. Needles are in singlets Spruce

3. a. Simple leaves (single leaf) go to 4

b. Compound leaves (“made of leaflets”) go to 7

4. a. Smooth edged go to 5

b. Jagged edge go to 6

5. a. Leaf edge is smooth Magnolia

b. Leaf edge is lobed White Oak

6. a. Leaf edge is small & tooth-like Elm

b. Leaf edge is large & thorny Holly

7. a. Leaflets attached at one single point Chestnut

b. Leaflets attached at multiple points Walnut

How many different leaf margin structures can be observed?

What leaf margin did the leaf you collect have?

Agenda Housekeeping

Leaf Structure & Function

HousekeepingWe will be going outside tomorrow, 4 May.

• Collect leaf samples

• Match as many structures as possible.

Quiz 5 scheduled for Friday, 5 May.

• Leaf structure & function.

Progress reports will be going out Friday, 5 May.


Leaf FunctionLeaves have four main functions:

• Manufacture food (photosynthesis)

• Protection

• Support

• Storage

Leaf FunctionManufacture food (photosynthesis):

• Takes place in the chloroplasts of plant cells.

• Two step process consisting of a light-dependent reaction &

light-independent reaction.

• Requires energy & reactants to create products:

6CO2 + 12H2O + Light C6H12O6 + 6O2

Leaf FunctionProtection:

• Newly developing buds like flower buds,

apical buds, & axillary buds.

• Protect buds against frost, desiccation, &

pathogens

Support:

• Growing in a spiral form, that stretches

out & curls around support structures to

help climb.

Leaf FunctionStorage:

• Water & food.

How many different structures will your group be searching for

during the scavenger hunt?

Agenda Housekeeping

Leaf Scavenger Hunt

HousekeepingQuiz 5 scheduled for tomorrow, 5 May.

• Leaf structure & function.

Progress reports will be going out tomorrow, 5 May.


Scavenger HuntEach group will collect as many leaves as necessary, matching

as many of the leaf structures as possible.

Each sample must be brought back to the classroom.

Group who matches the most structures wins a prize.

Supplies:

• Clipboard & pen/pencil

• Glossary of leaf structures

• Shoe box

• Pruning sheers

• Your are allowed one 3x5 card

(no cutouts) front & back.

Entry TaskTake the next couple of minutes to prepare for the quiz.

Quiz #5Write your name at the top of your quiz. All work must be shown

& completed on the quiz sheet.

Remember…

• No talking.

• Keep your eyes on your own paper.

• NO electronics. Calculators & phones in calculator mode only.

When you are finished…

• Check to make sure you thoroughly answered all questions &

you have shown your work on the quiz sheet.

• Silently read or complete missing assignments.

Agenda Housekeeping

Leaf Scavenger Hunt Scoring

HousekeepingProgress reports will be going out this evening.

Scavenger HuntEach group will receive the box of another group.

You will review each leaf for the structures listed on the glossary

reference worksheet.

You will receive a red pen with which to mark those structures

you review & find correct.

Red marks will be totaled for a final point score.

If there are any disagreements the teacher is the final arbitrator.
