5. BIOLOGIC LAB
Several of the samples found in the crime scene contain cell rests. We will have to check if there are elements that are likely to cause the death of John Carles, as if there are traces of onion cells in the sandwich or if there are microorganisms in a bottle of mineral water. We also have a cup of coffee with human cells of the buccal mucosa and fingerprints that can give us clues. We have to inform about the cells, the different types and how we can observe and classify them.
ACTIVITY 6:
We are going to "place" the cell first within the complex organization of living beings. We see the following website: Levels of organization of living beings and we see playing with "From DNA to biosphere"

Why is the cell so important when we talk about living things? We see these website and video:
Now we solve the following questions, first individually and then we put it in common. Can you make a diagram with the levels of organization of living beings?
Why do we say that the cell is the vital unit of living beings?
Name the organelles of the following cells:
Name the organelles of the following cells:
What elements do the plant and animal cells have in common?
Which are different?
We relate the functions of the cellular components with the words of this list: Reproduction, movement, energy, protection, container, photosynthesis

We add 5 points obtained from this assessment. Carry on!
ACTIVITY 7:
The size of the cells is so small that you have to observe them with microscope technology. We observe this animation of the cell size: Cell size and scale and we discover the size of:
A grain of rice
A paramecium
An epithelial cell (skin cell)
A red cell (red bool cell)
E. coli bacteria
The AIDS virus (HIV)
We look on the Internet for the microscopic measures that appear in the animation and define them:
Μm = micrometer
Nm = nanometer
To what extent can we see with our eyes?
What can we see in an optical microscope?
What cannot be seen even with an electron microscope?
We add 5 points obtained from this assessment. Continue!

Before going to the laboratory we see this animation of the operation of a microscope and its main parts.
We are ready to examine the rest of the evidence. We return to the beginning to begin to analyze the sandwich and press the 6.
