Have a great Winter Break - Have a good break

After winter break we will get into discussion groups to plan a guided tour of Central Park which will happen at the end of January.  We will also start a unit on virus, monerans and disease vectors

Take evolution note today (5 marks). test next wednesday

last period, we went over these notes on evolution, 
On monday, I would like for you to review the concepts in this set of notes:
How evolutionary change occurs
and these slides which show illustrations
natural selection

Furthermore, view this video on the steps of speciation and take notes on this.  You will be given a work period mark out of 5 for making notes in your own words for "How evolutionary change occurs" and also for the Speciation video below.

Dichotomous Key Practice 5 marks

Today, you will create a dichotomous key for a group of at least 10 or more PLANTS FROM THE SCHOOL GARDEN (2-1)  or everyday objects (2-3)   today for 5 marks.  Hand this in within the class. Create BOTH a spider key and a question key.  And an illustration of each object.

You are to create a dichotomous key for the plants you observe in central park.


EXAMPLES OF DICHOTOMOUS KEYS
Example of a key of just five items.  It shows a SPIDER KEY
and a question key:

Here are some examples of dichotomous keys on line.

Examples of Dichotomous keys:  web
What's That Tree?
Eek! Tree key
Common Trees of the Pacific Northwest

Test on Angiospermae Reproduction November 7th Wednesday

There will be multiple choice as well as long answer on this test

The test is on the following material: 

1.  Angiospermae Reproduction in the textbook pages 267-274

a.  What is the purpose of a flower?
b.  label the parts of a flower, which parts are male, which are female?
c. What does the fertilized ovule turn into?
d.  How are angiosperms different from gymnosperms in their reproduction?
e. Explain how double fertilization happens
f. What are the many adaptations for seed dispersal?
g. Explain the advantages of pollen and some of the methods of pollen dispersal
h.  Fig 10.17   Explain how monocots are different from dicots.


Vocab words:  Know these definitions and how they relate to angiosperm reproduction: Be prepared to label these words on a diagram and also to explain how reproduction happens:

Angiosperm (means covered seed)
Co-evolution (with insects)
Flowers

FEMALE PARTS
Pistil, stigma, ovule
Petal,
embryo
Megaspore mother cell
 meiosis, mitosis, mitosis, meiosis, haploid n
egg,  spare nuclei, polar nuclei

MALE PARTS
Stamen, anther, filament
microspore mother cell
meiosis, mitosis, mitosis, meiosis, haploid n
n+n      pollen

FERTILIZATION
stigma, pollen
generative nucleus, tube nucleus
generative nucleus --> sperm nuclei
tube
double fertilization
2n embryo -->  new plant
3n endosperm  --> "baby food" for the new plant  --> cotyledon

PARTS OF SEED
seed coat
3n endosperm
2n embryo
it's a monocotyledon = corn, rice    or a dicotyledon= soybean,  peanut,  cashew

OVULE or RECEPTACLE eventually become FRUIT
a drupe or a berry or an accessory or an aggregate

Your colouring diagrams.  Be prepared to identify certain flowers and fruits according to these diagrams:

2. Your class notes on Angiosperm reproduction

Flower Lab /20 and Seed lab also /20

I gave you a colouring book showing the structures of flowers, leaves and fruit.
Use this as a reference.


FLOWER LAB IS OUT OF 20 MARKS
Go into the school garden and find the following specimens.  Bring them back for dissection and observation under the dissecting microscope.
Draw each specimen.  2 marks
Identify the flower type and label the parts.  2 marks
Write one interesting observation you notice  1 mark

 Each drawing should be at least a half page.  You should have three specimens:

Use a big legal size paper to draw your observations.

1.  Find a small HEAD type of flower  (simlar to a sunflower)  It ought to have a disk flower and ray flower within the head.  Observations:  Count the disc flowers in your specimen.  What is the advantage of this kind of flower?

2. a.  Find a SPIKE type of flower
    b.   Find an UMBEL TYPE of flower
 
3.  Find a BASIC FLOWER.  Is it hypogynous, perigynous or epigynous?  Draw it and label its parts

CONTENT:  YOU COMPLETED THE ASSIGNMENT    15 MARKS  (5 marks per question)
you answered all the questions with care and you discover something interesting/

CARE IS TAKEN IN DRAWING and observing   out of 5
6/5   you make exceptional,  careful drawings with clean lines.  It is beautifully done and neat, it's in colour.  This stands out.  Bonus marks
4-5/5   you make exceptional careful drawings. This is beautifully done and neat
2-3/5   your drawings are complete and neat
1/5      you needed more time as your drawings seem a bit rushed and incomplete.


SEED AND FRUIT LAB  ALSO OUT OF 20 MARKS

For each specimen, draw it and label its parts.  Write a few sentences that describe its role in angiosperm reproduction. Each drawing should be at least half a page and neatly drawn, in colour.

draw three seed specimens 5 marks:  Which of these are dicots and which are monocots?  How do you know?
soybean sprout
corn nut
coconut


Fruit specimens: 5 marks Classify these according to your colouring book
strawberry
dragonfruit

find one more fruit  OR seed specimen in the school garden 5 marks
