ACTIVITIES
REVISION In this session will be used the methodology to work in pairs, to
do activities about previous knowledge, where the students
should to answer question like these: Do you remember what
types of cell are there? Do you know the functions of organelles?
Why do you think that the nucleus is very important in the cells?
Can you remember your function in the living creature?
WARM UP
ACTIVITIES
Cells and Organelles
QUESTION 1: Why do you think that cells - animal, plant, or
bacteria - don't get any bigger than this? Why do you think we are
made of 75 trillion very small cells, rather than just a bunch of
very large cells?
QUESTION 2: How do you think cells become specialized for their
function? For instance, we all started our life as one single
fertilized egg cell, but within weeks or months of conception, we
had liver cells, heart cell, brain cells, muscle cells. How does one
cell give rise to many cells with many different functions??
QUESTION 3: In what cells of your body would you expect to find
a lot of mitochondria? Why?
MAIN ACTIVITIES Question 1) Answer this questions:
a) Why is the cell the organisational and functional unit of living
things?
b) What organisms are made up of prokaryotic cells? And of
eukaryotic cells?
Question 2) Choose the correct option:
a) Prokaryotic cells have/don’t have a nucleus.
b) Prokaryotic cells are more/less primitive.

ABSTRACT
In this Didactic Unit the objective is that the students to know in more detail the
most important characteristics of the cell.
The students should to have the capacity to differentiate between different cell
types, eukaryotes and prokaryotes must learn to differentiate between animal and
plant cells and organelles for each of them.
Finally they will learn the processes of cell division: Mitosis and Meiosis and the
importance for the life of the living beings of planet Earth.
In the other hand, to achieve all this, I will use a dynamic methodology, integrative
and very didactic.
CONTENT
The Cell 1. The Cell Theory:
The first observations of cells date back to 1665, when Robert Hooke, using
a very simple microscope handmade by himself, observed a thin slice of cork.
He discovered on it geometrical tiny pores that he called “cells”. However,
Hooke did not know their real structure or function. In 1674, Anthony van
Leeuwenhoek observed and described for the very first time living cells.
These cells were microorganisms (bacteria and protozoa) that he had
discovered in pond’s water, and that he called “animalcules”.
Since the XIX century, the improvement of microscopes and the development
of staining techniques, allowed to observe the internal structures of cells.
Robert Brown discovered in 1831 a corpuscle inside the plant cells that he
called “nucleus”. Seven years later, in 1838, Johannes Purkinje introduced the
term “protoplasm” to refer to the liquid which fills the cells. Matthias
Schleiden and Theodor Schwann, independently, came to the conclusion that
all plants and animals were formed by cells. Finally in 1855, Rudolf Virchow,
established that every cell came from a previous cell. With the postulates of
Schleiden and Schwann, the development of the Cell Theory started. Today
we can summarise it into the following points:
- Cell is the vital unit of living beings. The cell is the simplest and smallest
living being.
- Cell is the structural unit of living beings. All living beings are made by one
or more cells.
- Cell is the functional unit of living beings. The cell is able to perform all
metabolic processes that allow it stays alive, that is, carry out the vital
functions.
- Cell is the genetic unit of living beings. Every cell comes from other pre-
existing cell, from which it inherits its genetic material.
2. Types of cells.
Living beings can have two different types of cell organization: prokaryotic and
eukaryotic.
- Prokaryotic cells:
They do not have a nucleus. Their genetic material is inside the cytoplasm
without a membrane that separates it from the rest of its content. In addition,
they do not have organelles, except ribosomes.
These cells are more primitive, simpler and smaller (from 1µm to 10 µm) than
eukaryote cells and they are exclusive of bacteria (Monera Kingdom).
- Eukaryotic cells.
They have a true nucleus that means that their genetic material is
surrounded by a membrane that separates it from the rest of the cytoplasm.
They have numerous organelles.
These cells are more evolved, more complex and bigger (from 10µm to 100 µm)
than prokaryote cells. The rest of living beings (Protoctists, Fungi, Plants and
Animals Kingdoms) have this type of cells.
There is two types of eukaryotic cells:
- Eukaryotic plant cell: They are the cells of plants and algae. They have some
exclusive organelles: chloroplasts and cellular plant wall. This is a rigid external
cover of cellulose, which protects the cell and gives it a polyhedral shape. In addition,
their vacuoles are large and little numerous. Usually there is only one.
- Eukaryotic animal cell: They are the cells of animals and protozoa. They also have
some exclusive organelles: the centrosome and the cilia and flagella. They have a
flexible external cover. In contrast they have many little vacuoles.
3. Mitosis and Meiosis
Learning about mitosis and meiosis in biology class can be challenging for students.
Understanding how mitosis and meiosis work is essential for understanding
independent assortment, genetics, and evolution so I spend a lot of time on this unit.
I use a few different methods for helping students understand and really grasp the
material.
1. I show a lot of animations: Mitosis is dynamic process. Chromosomes are
moving in all moment It is really important for them to see the process in
action. There are loads of great animations online for teachers.
o Stages of Mitosis
o How Meiosis Works
o Independent Assortment (Meiosis Orientation of Chromosomes)
o Stages of Meiosis Virtual Cell: Mitosis
2. A teacher at a school I used to work at does a really cool project during this
unit. We will work making student groups create stop motion animation
videos of either mitosis or meiosis. Students are allowed to use any materials
they want and the video has to have pictures.
GLOSSARY (A – Z)
Chromosome
A thread-like structure of nucleic acids and protein found in the nucleus of
most living cells, carrying genetic information in the form of genes.
Cellular wall
It is a rigid and hard envelop formed by polysaccharides and proteins that
gives shape to the bacterium. It has a protective function.
Chloroplast
A plastid in green plant cells which contains chlorophyll and in which
photosynthesis takes place.
Eukaryote
An organism consisting of a cell or cells in which the genetic material is
DNA in the form of chromosomes contained within a distinct nucleus.
Eukaryotes include all living organisms other than the eubacteria and
Achaea.
Flagella
They are thread-like organelles projected outside of the cell which allow
its movement.
Fimbria.
They are rigid and short projections that are involved in the adherence.
Meiosis.
A type of cell division that results in four daughter cells each with half the
number of chromosomes of the parent cell.
Mitosis.
A type of cell division that results in two daughter cells each having the
same number and kind of chromosomes as the parent nucleus.
Nucleoid
It is the bacterial chromosome, a single circular filament of DNA without
a membrane.
Nucleus
A dense organelle present in most eukaryotic cells, typically a single
rounded structure bounded by a double membrane, containing the
genetic material.
Plasmatic membrane.
It is flexible envelop similar to eukaryotic cell membrane. It is located
below the cellular wall and its functions are to control the pass of
substances into and out of the cell. It presents numerous folds towards
the cytoplasm. In these structures take place very important metabolic
reactions, such as photosynthesis and respiration.
Prokaryote
A microscopic single-celled organism which has neither a distinct nucleus
with a membrane nor other specialized organelles, including the bacteria
and cyanobacteria.
Ribosomes.
They are organelles made up of protein and RNA that perform the protein
synthesis. These ribosomes are similar to eukaryotic ones but they are
smaller.
Vacuole.
A space or vesicle within the cytoplasm of a cell, enclosed by a membrane
and typically containing fluid.

APPENDIXE
SELF-ASSESSMENT
In my opinion, it is essential to make an evaluation of the teaching process. It is a
tool that helps teachers to improve our work and to know what are the needs of our
students, in order to help them as much as possible in their learning process and to
help them for acquiring security in themselves when they have to go out and find
work.
In the other hand and respect to the didactic unit of the cell, I think it is very
important that I know the contents studied so that they can understand the origin
of the species that inhabit our planet and for that reason I consider that it is a matter
of vital importance to impart it. My methodology is dynamic and integrative, very
didactic for the use of audio visual resources, but I would like to wish I could have
more time to practice in the laboratory.
