Mr. Hwang's ECHS 2011-2012 1st Trimester Biology Class Page Welcome ECHS students and parents! Have you ever been unsure of what's going on in class? Having trouble remembering when your assignment is due?

Ever needed to contact a teacher for assistance after school hours? Well you've come to the right place! Here you can find up-to-the-minute announcements, deadline reminders, and other important class info straight from your computer or smartphone.

So I came back to the room today to get things ready for tomorrow when I noticed my filing cabinets looked they've been rummaged through in my closet.

By my logic, a student or more went in looking for the scorpion lollipops and choco. Covered insects. They didn't find the lollipops but managed to STEAL all but one package of chocolate covered crickets. I

I am ABSOLUTELY FURIOUS with the student(s) that did this. Those were $50 and now everyone else can't enjoy these prizes.

I'm contacting each sub I've had to ask if they saw or let anyone into that closet. If any of you know anything about this, please discreetly private message me. Thanks and hope you have a great 2nd trimester!

Oct 21 Notes:

Protists infect organisms in cyst form and often cause diarrhea and cramps.
Examples:
1) Giardiasis
2) Amebic Dysentery
- amebiasis (mild)
3) Cryptosporidiosis

Protists can also be spread by cats (Toxoplasmosis), sexually transmitted in humans (trichomoniasis), by kissing bugs (chagas disease), and by mosquitoes (Malaria).

Protists: eukaryotic organisms that are not clearly classified as Fungi, Plants, or Animals.

Protista Asexual Reproduction:
1) Binary Fission: splitting in half.
2) Budding: part of the parent pinches into new organism
3) Fragmentation: budding due to the environment/predator.

Protista Sexual Reproduction:
two gametes fuse to form a diploid zygote. Mature organism repeats cycle.

Friday (Oct 14th) notes:
Angios***m = flowering plants that produce fruits around their seeds.

Two subgroups of angios***ms
1) Monocots
- 1 cotyledon
- parallel veins
- flower parts in sets of 3
- vascular tissue arranged throughout.

2) Dicots
- 2 cotyledon
- netlike veins
- flower parts in sets of four or fives
- vascular tissue arranged in a ring

10/14/2011

2 groups of seed plants:
1) Gymnos***ms
-does not bear fruits
2) Angios***ms
-bears fruits

Pollination: form of reproduction where plant s***m (pollen grains) travel to the ovule (female reproductive center).

Oct 12 Notes:
Obstacles of plants adapting to life on land:
1) Need support structure (cell walls)
2) Need to retain water (cuticle)
3) Need to disperse spores, seeds, pollen.

To absorb nutrients, plants developed roots.
Also, plants developed symbiotic relationships with fungi called mycorrhizae.
Fungi are experts at absorbing nutrients. They share it with the plants. Fungi have a home at the plant's roots.

Oct 11 Notes:
Characteristics of Plants:
1) Multicellular - "many cells"
2) Eukaryote
3) Cell Wall -made of cellulose
4) Autotrophic - most produce their own food

10/11/2011

Oct 10 Notes:
Fungi share 3 characteristics
1) Threadlike bodies
2) Cell walls made of chitin
3) Heterotrophic (absorb food)

Fungi used for:
1) food
2) antibiotics
3) alternative fuels
4) soft drinks and snacks
