Cell Biology Learning GoalsA. Micro Knowledge• I can use a Compound Light Microscope & tell the names and functions of its parts.
• I can draw micro-figures that show key parts of plant & animal cells AND explain the function of each key part.
B. Cells and Characteristics of Living Things
• I am able to explain why cells are the fundamental unit of all life. (The Cell Theory)
• I can tell the functions (characteristics) organisms must do be “living”.
• I can explain the relationship of different parts of the “living” universe to one another.
• I can show how one-celled organisms have all the parts needed to do life functions.
• I am able to identify plant & animals cells & point out their similarities & differences.
• I know how the structure of a specialized cell is related to the function the cell performs.
C. Systems: • I can trace key components of life (O2, Food, Water) into & out of plant & animal cells.
D. Experimenting:• I can properly plan, conduct and write up any kind of experiment.

The Cell Theory1. All living organisms are made up of one or more cells.
2. All living cells come from preexisting cells by division.
3. The cell is the basic unit of structure & function in all living
organisms.
4. Energy flow occurs in cells
5. Cells contain heredity info (DNA) that is passed to other cells
during Cell Division
6. The activity of an organism depends on the total activity of its
independent cells.I am able to explain why cells are the fundamental unit of all life. (The Cell Theory)

Absorbs light energy & uses with H2O and CO2 to produce (glucose) energy for cell
Breaks down nutrients from food and builds the new substances needed to grow or carry out other functions
Uses O2 and Glucose to produce most of the energy the cells needs. Contains the majority of the genetic information of cell, (DNA) directs cell activities
Separates the nucleus from the rest of the cell.

All but Bacteria
Perform specialized cell functions (Mitochondria, Chloroplast, Nucleus…a. Obtain & store energy b. Help cells move & divide, c. Make substances used in cell or transported to other parts of the body.

Seven Characteristics of Living Things!!!!
a. Are organized to do simple and complex functions
b. Get, store and use energy: (i.e. make or take in nutrients, do work & release waste)
c. Keep proper internal balance (this is called homeostasis)
d. Grow
e. Respond to stimulus (ex: sweat, shiver, move, defend, flee etc)
f. Reproduce (each reproduced cell has a complete set of DNA)
g. Evolve (… adapt to environmental conditions over time.)
I can tell the functions (characteristics) organisms must do be “living”.
