How many rules are there in cell theory?
What is 3?
What is the formula to find magnification?
What is magnification = image size/actual size?
What are the seven characteristics of life?
What is metabolism, reproduction, sensitivity, homeostasis, excretion, nutrition, and growth?
They can continually divide and replicate.
What is self-renewal?
True or false: Light microscopes view specimens in monochrome.
What is false?
What are the 3 components of cell theory?
What is living things are made of cells, cells are the smallest unit of life, and cells only come from pre-existing cells?
What is the formula to find actual size?
What is actual size = image size/magnification?
Undertakes essential chemical reactions.
What is metabolism?
They have the capacity to differentiate into specialized cell types.
What is potency?
What are the 2 kinds of microscopes and their differences?
What is a light microscope (lenses to bend light, view in natural color, lower resolution & magnification) and an electron microscope? (electromagnets to focus electrons, views in monochrome, higher resolution & magnification).
Who discovered the cell?

A bacterial cell is viewed under a light microscope. The actual length of the cell is 4 micrometers. Calculate the magnification.
What is x12,500?
Exchanges material with the environment.
What is nutrition?
Embryonic stem cells can form any cell type.
What is totipotent and pluripotent?

What is the actual length of this mitochondria in um when it is viewed under a microscope with a magnification of X10000?
What is 7 um?
Response to internal and external stimuli.
What is sensitivity?
Adult stem cells that have a limited capacity for differentiation.
What is multipotent and unipotent?
How do electromicrosopes focus electrons?
What is with the use of electromagnets?
What are the 3 exceptions to the cell theory?
What is striated muscle, giant algae, and aseptate fungal hyphae?
The eyepiece lens of the microscope has a magnification of x10 and an objective lens of x40 was used to view the blood cells. The scientist takes a photomicrograph of the blood cells, in which the average size of each cell is 3 mm. What is the average size of the red blood cells in the sample? Give your answer in micrometres (um).
What is 7.5 um?
Maintains a stable internal environment.
What is homeostasis?
Stem cells can be used to replace damage or diseased cells with healthy function one.
