angiospermae reproduction

October 18 and 20

You will do a Webquest on Plant Evolution as well as a practice test based on some reading.
Remember to sign up for OWLS and bring the fee on 25th when I come back from the U.S.

If you REGISTER for Fall Parksfest and write about each of your sessions...

I will evaluate your write up for Biology.
I would like you to register for Parksfest and write about your experience of each of the workshops and lectures.  Please put down "Camosun Bog Buddy/Gladstone" as affiliation and Pacific Spirit Park.
This is an out of school optional activity not connected with Gladstone. If you do this it is your own choice.  You must register for Metro Van for this to count.

Central Park Field Study Oct 13, 2016 Canceled due to Environment Canada Weather warning

Our Field Study is canceled due to the following Environment Canada.  We will postpone this trip for another day!

 warning

Statements

11:40 AM PDT Tuesday 11 October 2016
Special weather statement in effect for:

• Metro Vancouver

The first in a series of powerful October storms will approach the BC coast late Wednesday night bringing heavy rains and strong winds. A second storm is expected early Friday while a third will make landfall later on Saturday.

Rainfall will be heavy at times. Total rainfall accumulations from these storms may exceed 200 mm for West and Inland areas of Vancouver Island. Inner coastal regions may exceed 100 mm with even higher amounts near the mountains.

Strong winds will also accompany these storms. Winds over exposed coastal areas may exceed 80 km/h at times during these storms.

As the storms develop and approach the coast, the details will become clearer. Weather warnings will very likely be issued for multiple regions and updated as needed.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to pacificstorm@ec.gc.ca or tweet reports to #BCStorm.

Remember to sign up for owls

Lab

Here is the outline of our latest Plant lab to examine the structures of different plants.  We'll work through this in the next little while.   Have a look.  we will use microscopes and also examine specimens.

Kingdom Plantae:

Evolution and Classification of land plants

Definition: Multicellular eukaryotic autotroph

With cell walls made of cellulose

1.Phylum Algae:  (used to be part of kingdom Plantae

Now it is considered part of kingdom Protozoa)

-       Lives in marine or aquatic environments

-       Uses diffusion for gas exchange, to absorb

Minerals

-       It uses swimming sperm and non motile eggs for

Sexual reproduction

a.     Examples:  Green algae, Red algae, Brown algae.

(seaweed)

Kingdom Plantae

2.  Phylum Bryophyta – land plants which are very delicate

They have no cuticle (protective waxy covering)

-       They use diffusion for gas exchange

-       Use swimming sperm and they have eggs

-       They have gametophytes, which are separate sexes

They have male and female gametophytes.

Sperm swim from males to females.

Examples: 1. Moss

                  2.  Hornwort

                   3.  liverwort

3.  Phylum Tracheophyta – land plants which have some of the following

characteristics

-       Have a cuticle

-       Have vascular tissue (conducting tubes which can deliver minerals,

Water, glucose)

-       Have stomata – “breathing holes” for gas exchange

-       Are much bigger than bryophytes

-       Examples are

-       1.  Subphylum Pterophyta – All ferns. 

2.  Subphylum Sphenophyta – Horsetails.

FERNS AND HORSETAILS HAVE SWIMMING SPERM

3. Subphylum Spermophyta – All plants which make seeds

including trees of all kinds and including flowering plants.

SPERMOPHYTA DO NOT HAVE SWIMMING SPERM. 

THEY MADE AN INNOVATION IN EVOLUTION: POLLEN

THEY DO NOT rely on water for SEXUAL REPRODUCTION.

-       They all have vascular tissue – some extend quite high up.  Tall trees

-        All have cuticle, stomata.

-       A.  “GYMNOSPERM GROUP”  -

-       1.  CLASS GINGKOAE – ginko

-       2.  CLASS CONIFERAE – all evergreen trees

-       3.  CLASS ANGIOSPERMAE – all plants that are deciduous trees, AND ALL

-       FLOWERING PLANTS.

THREE EVOLUTIONARY TRENDS

1.      EARLY PLANTS need water to sexually reproduce, LATER PLANTS DON’T

SEXUAL REPRODUCTION REQUIRED sperm and egg in early plants. Later plants used pollen, using wind.  And the most recent plants use vector pollination. 

ALTERNATION OF GENERATION
plants alternate between two generations.  It is as if they use a different body form every other generation.  For example, a male gametophyte mates with a female gametophyte and they create their offspring, a sporophyte.  Then the sporophyte makes the next generation, gametophytes.  

Imagine if you looked exactly like your grandparent and your child looked exactly like your parent

Central Park Field Study for New Biology Class

We will be visiting central park.  please fill in this online consent form and have your parents sign the paper form

Owls in our Gladstone Learning Commons! October 25 1-230 and October 28 10 - 1130

some very special guests will be visiting Gladstone Library:
Please register for this event in the link below

REGISTER FOR OWL PRESENTATION
Note that there is a fee/donation for OWL

Their mandate, quoted from their website is:

"Orphaned Wildlife Rehabilitation Society is a non-profit organization whose volunteers are dedicated to public education and the rehabilitation and release of injured and orphaned birds. O.W.L. became a Society in January 1985 (Registration No. S-19879). O.W.L. is licensed through Fish and Wildlife, now known as the Ministry of Forests, Lands and Natural Resource Operations.
O.W.L. is on call seven days a week, twenty-four hours a day. Public tours are available daily in July and August and every Saturday and Sunday from September to June between 10:00am and 3:00pm.

 The facility specializes in raptors (i.e. eagles, falcons, hawks and owls). Birds of prey patients at O.W.L. number over four hundred each year and as O.W.L.’s facilities have expanded, so has the intake. Primary care for injured birds (i.e. fluid injections, tube feeding, and initial treatment of broken bones to stabilize) is administered by staff. Veterinary care (i.e. surgery involving the pinning of fractures, radiographs and amputations) is contributed by local clinics such as Huff Animal Hospital, Richmond Animal Hospital, and Tsawwassen Animal Hospital."
