NOTES ON CLASSIFICATION

please correct the following in these notes: Vaccinium ovatum should say Vaccinium ovalifolium and also the notes show the old classification. today the new classification is:

Kingdoms archaea , bacteria (formerly monera ) and eukarya

and under the eukarya kingdoms kingdom animalia, fungi and plantae

Answer these questions

1. What is classification? Who invented it?
2. Explain the term binomial nomenclature
3. What are the taxons of life, in order of largest to smallest?
4. Define species.
5. Cell respiration is a universal energy equation. Where does it happen? Write the equation.
6. What is ATP, ADP. Give an analogy for how this works
7. Define Heterotroph and Autotroph
8. ACCORDING TO THESE NOTES, What is the definition of
a. Animal
b. plant
c. Fungus
d. Protozoa
e. Monera

Hey Eu! Eukaryotes vs Prokaryotes

watch this intro video on Eukaryotes and Prokaryotes

This video is an intro to some of the similarities and differences between eukaryotes and prokaryotes. It is meant to accompany our class notes.

Vocabulary words and ideas in the video:

Eukaryote Prokaryote DNA nuclear membrane protozoan multicellular organisms unicellular organisms cell membrane, cytoplasm, DNA, RNA, ribosome, protein, endoplasmic reticulum vacuole mitochondria Plant cell chloroplast cell wall made of cellulose cell wall made of peptidoglycan Bacteria in the environment and the gut

MAKE a model of the cell out of lego: Make one eukaryotic cell and one prokaryotic cell
Make a creative summary of these notes. The summary must cover all of the points below:

1. What are the 4 criteria to life?

2. What are the two main types of cells on earth?

3. Give an example of a. UNICELLULAR organism b. MULTICELLULAR organism

4. I gave an example of the cell as a chocolate factory. Make your own analogy of the cell and include EVERY ORGANELLE. You may choose a plant cell or an animal cell.

5. How are plant cells different from animal cells?

6. What are four ways that cells can interact with each other. below

evaluation: 20 points

Classification Activity

1. Read 196-199 in the Biology Textbook

and make point form notes on these pages, copying fig 7.2 an 7.3. Write all the definitions of words in bold: binomial nomenclature, species, dichotomous key, Taxa, phylogeny.

2. Examine all the specimens in class

a. draw the specimen using a half page per drawing

b. Identify the Kingdom or phylum

c. What are the adaptations?

d. What is your evidence for your answer for b?

: Dead or Alive

For your first assignment, I would like you to go outside and find the following objects Photograph them or draw them and write about them in a little paragraph of no more than a third of a page. You may answer in the form of a type written response under your photo, OR you may write it out in hand writing and draw your answers.

1. Find something dead. How do you know it is dead?

2. find something alive. What is it about this object that makes it alive?

3. Find something that has never, ever been alive. What characteristics does this object have that tells you that it is neither dead nor alive. It is nonliving.

4. Find something that is not alive, but an important PART of something alive. Explain your answer

5. What is something that is not alive but a living thing depends upon it to survive?

Look at your responses and ask yourself: What is the criteria of being alive?

Criteria for living things:

What are the criteria for living things?
1. MOTILITY - the ability to move
2. IRRITABILITY - it responds to stimulus
3. REPRODUCTION - it can reproduce and make offspring

a. it can grow

b. it can make another one of itself
4. It is made of CELLS

5. a. HAS METABOLISM -total of all biochemical reactions

occurring in a living thing. If metabolism stops...then that

is death.

b. TAKES IN NUTRIENTS and MAKES WASTE

CELLS (definition)

-A membrane bound organism that has cytoplasm and genetic material. It also has METABOLISM happening inside it.

-ORGANISMS CAN BE UNICELLULAR (made of a single cell) or MULTICELLULAR (made of many cells)

-ORGANISMS CAN BE EUKARYOTES or PROKARYOTES

Eukaryotic cells have DNA inside a nucleus. Prokaryotic cells have DNA in the cytoplasm but no nucleus. Prokaryotes are bacteria

Eukaryotes are animals, plants, fungi, unicellular protozoans, seaweed.

6. CELLS have HOMEOSTASIS - maintaining the status quo for temp,
pH, levels of hormones, levels of enzymes.

7. CELLS CAN adapt to change in the environment.

Organelle systems provide everything for the cell
1. energy for the cell - this is in the form of ATP made
by mitochondria.The mitochondria needs GLUCOSE and OXYGEN.
GLUCOSE IS FROM DIGESTIVE SYSTEM.
OXYGEN IS FROM SYSTEM AND
RESPIRATORY SYSTEM.

2. eating and drinking - cell receives building blocks such as
AMINO ACIDS, LIPIDS, NUCLEIC ACIDS from the
DIGESTIVE SYSTEM AND CIRCULATORY SYSTEM

3. waste is taken away by diffusion

4. communication for the cell
5. cells defend themselves

6. Reproduction of the cell

ANY ANIMAL CELL inside a mammal...

Eating building material such as amino acids, lipids nucleic acids

Energy: glucose and oxygen goes to mitochondria and carbon
dioxide leaves mitochondria

Waste: ammonia

Drinking water

cell product: made by the cell as specified by the DNA. For example,
a pancreatic cell makes INSULIN

parasitic worm assignment

PARASITIC WORMS ASSIGNMENT:

Several Children in Vancouver were sent to your clinic with the following symptoms: In each case:

Examine the specimen and attempt to identify the organism. What phylum of parasitic worm do you think this is? Furthermore, give evidence for your diagnosis and offer a course of action to cure the patient and prevent further infestation: Also, devise a method to contain any possibility of outbreak.

Kitty Pride is a young woman who lives in a mansion in Southlands in a special School for gifted youth. She was experiencing abdominal symptoms of bloating and cramping, and enteritis in general. She also noticed that she has been feeling unusually anemic, lately. Blood work indicates an elevated white cell count. Sample C was found in her stool sample

Walt Chan is a two year old boy, with two sisters and a pit bull . He is an active toddler who likes to play in the outdoors. Walt has recently developed enteritis of unknown origin. His symptoms included bloating, cramping (which made him cry at night) and mild “car sickness” symptoms. When Walt went in for blood tests, his white blood cell count was found to be elevated, particularly his eosinophils. Furthermore, a stool sample yielded the specimen A.

Vince Man is a two year old boy who lives in Kerrisdale. Vince is an active toddler who loves to play in the outdoors. He lives with his parents but is cared for by his grandmother who loves to cook traditional northern Chinese food for him. Vince goes to a daycare part time where he plays with other children ranging from age 1-3. Vince began getting unusual enteritis with an elevated white blood cell count. His grandma was horrified one day to find sample Z in his stool.

Sebastien Slartibartfast is a two year old boy who lives in Kerrisdale. Sebastien has been complaining of an itchy bum for several weeks. His scratching is beginning to damage his skin and rectum.He is an only child with many pets: a hamster, a cat and two zebra finches. Sebastien also attends a daycare that admits children ages 0 to 3. Sample E (sample D) was found in Sebastien’s stool sample. Sebastien’s Dad has noticed that he has similar symptoms as Sebastien. (itchiness). Sample B was found in his stool.
