Cell structure

Copy these notes in your book, answering questions.





A Cell is Bag of life, that makes copies of itself.

Describe what a cell would look and feel like if it where the size of a tennis ball.



What instrument do you need to see most cells?_____________________





This is an artist impression of a AIDS virus. Sketch this in you book. What do you need with all sketches to tell people about the size of what they are looking at? What do you think is happening in this picture.

Use the scale in this link to find the length of a Cholera germ. What kind of microscope was this pictured with.



Sketch an cell as you would see under a microscope
- use pencil
- half a page
- dashed circular line shows limit of field of view
- include a scale
- include a title
- label parts and include a legend

On completion show the teacher for marking.


Note this in your book




Prokaryotic - Cell like bacteria primative

Eukaryotic - Cell with organelles inside

Give a few examples of each


What is an organelle? _________________________


Some organelles are cut down copies of simple Prokaryotic Cells, How do you think this happened? ______________________





All cells use DNA (Deoxyribonucleic acid ) to store information used by the cell to make the parts of the cell that the cell needs.

Look at this video and describe what you see.

The nucleus stores the DNA so it can be read to make parts for the cell, but the nucleus wall dissolves when the cell is dividing.

What are cancer cells? This is a photo of cancer cells can you tell what gives it away?

Goto a interactive model of a cell draw a table of the organelles, Name, What they do

Microscope Rules

Microscope Rules:

Scientific Drawing rules
label drawing
write what it is
date it
write magnification from number on the side of the eyepiece and the number on the adjuster.
clear lines
no shading
use pencil
do big diagram
do cell wall
label nucleus
all writing goes around the drawing with arrows pointing in or using a, b, c

Steps for setting up microscope:

1. Hold microscope on the bottom with one hand and top with the other
2. Plug microscope in and turn on light
3. set to the lowest power
4. gently slide the specimen underneath the clamps with the cover slip directly above the lights
5. raise the stage. mke sure you don't crack the slide. slowly lower stage to focus

Setting up slide

1. Grab a slide and cover slip
2. put specimen on slide
3. put 1 drop of water on specimen
4. put cover slip over the specimen on an angle. press any air out.
5. mop up any extra water.

Matter Round Up

We need to do an online topic test.

For this you will need to revise:
1> How is matter different from heat and energy.
2> What and Why some states of matter can or can't be compressed
3> How Diffusion works
4> What particles are like and what how they move in states of matter.
5> What happens to interparticle spacing when a solid is heated
6> Basic properties of matter.
7> Understand and recall the Donut of matter transformations
8> Recall the particle diagrams of the states of matter.
9> Understand condensation
10> Recall when matter is changing state its temperature is constant while it does so
11> Identify condensation, and energy transfer
12> Volume calculation of irregular objects by liquid displacement
13 > Experimental Safety
14> Properties of various states of matter
15 > Graphing exercise and interpretation of heat transfer by different matterial


More support

During State changes-
Heat drives change from solid to liquid, and liquid to gas and temperature of the mixture is constant ( Water Freezes at 0 and Boils at 100C at sea level.)
The energy is required because the particles are in energy pits or wells in the lower states.
When the reverse happens, Condensation or Freezing, the Matterial supplies heat to the environment as the particles move into their energy pits.
