Unit 5 - Cell biology 19 -Dec,2022
- An illustrated report by Pietra Afoakwa
INTRODUCTION
This illustration report aims to show my comprehension towards cell biology
with informative provision on diagrams and tables by identifying the basic
structures of cell, impacts viruses have on them and sub – cellular structures
and organelles of eukaryotic cells. I will also explain cellular metabolism
where I will explain the role of the cell membrane regarding the intake of
nutrients and lose of waste, how animal cells use nutrients to provide energy for
growth, movement and cell division. My report will contain information on
cellular growth and division embryonic stem cells. I will also discuss genetic
information relating to daughter cells.
To present this knowledge, this report will use information from images, tables
and various sources of text and educational videos, including the information
and videos provided in the study materials provided with this course.

Characteristics of living cells.
A cell is simply the smallest or basic unit of life that is responsible for all life’s
processes. It is the smallest unit that can live on its own and make up all the
living organisms and tissues of the body. All cells must carry out all these to
function in order to survive; thus
Movement, respiration, sensitivity, growth, reproduction, excretion and
nutrition by using the “MRS GREN” acronym:
Movement – cells must be able to move
Respiration – vital energy production
Sensitivity – respond to environment
Growth – develop or grow and complexity
Reproduction – continuing in species
Excretion - to remove toxic metabolic waste
Nutrition - they can take in and absorb nutrients

, Prokaryotic and Eukaryotic cells
Cells can be categorised into two types. The simpler form known as
Prokaryotic, and the complex form known as Eukaryotic.
Prokaryotic cells include bacteria and archaea. Prokaryotes organisms
composed of a prokaryotic cell are always single-celled which is termed as
unicellular. Prokaryotic cells don’t contain a nucleus. Instead, their DNA can
be found in the cytoplasm in a region called the nucleoid or in circular
chromosomes called plasmids whilst
Eukaryotic cells can be found in animals, plants, protists, and fungi. Eukaryotes
—organisms composed of eukaryotic cells—are multicellular or complex
unicellular organisms. Eukaryotic cells have a membrane-bound nucleus where
their DNA is stored.
A prokaryotic cell is a type of cell that does not have a true nucleus or
membrane – bound organelles. They belong to groups such as bacteria and
archaea. they are primitive and tolerate extreme environmental conditions such
as extreme temperatures, acidity levels and salinity. The structure of a
prokaryotic cell is surrounded by a plasma membrane, but it does not have an
internal membrane and organism within their cytoplasm. These cells do not
have a nucleus, but their DNA is coiled in their nucleoid.
