This document provides an overview of cells including their characteristics, types, parts, and functions. It begins with defining the cell as the basic structural and functional unit of living organisms. It then discusses the characteristics of cells, including that all living things are made up of cells, cells are the smallest units of life, and all cells come from preexisting cells. The document goes on to describe the types of cells including prokaryotic and eukaryotic cells as well as unicellular and multicellular organisms. It also provides information about the parts of plant and animal cells and their functions. Diagrams are included to illustrate cell structures.

6. What is Cell?
Cell is the basic structural and
functional unit of living organisms.
In other words, cells make up living
things and carry out activities that
keep a living thing alive.

7. Cells are considered the basic units of life in part
because they come in discrete and easily
recognizable packages. That's because all cells are
surrounded by a structure called the cell membrane
— which, much like the walls of a house, serves as a
clear boundary between the cell's internal and
external environments.
Why cell is considered as the basic
structural unit of life?

8. CHARACTERISTICS OF CELLS
All living things are made up of cells.
Cells are the smallest working units of
all living things.
All cells come from preexisting cells
through cell division
 All cells are the basic unit or building
blocks of all living things.

Multicellular
Unicellular
An organism that is made up
of only one cell is called
as
unicellular organism.
An organism that is made up of
more than one cell is called
as multicellular organism.

19. Prokaryotes
 A unicellular organism made
of one prokaryotic cell is
called a prokaryote.
 Prokaryotes are cells without
a membrane bound nucleus.
 Prokaryotes are smaller than
eukaryotic cells.

20. Eukaryotes
 A unicellular organism that is
made of one eukaryotic cell is
called a eukaryote.
 A eukaryotic cell has a nucleus
surrounded by a membrane.
 A eukaryotic cell has may
specialized organelles.
 Eukaryotes can be either
unicellular or multicellular

30. The nucleus is the control center of
the cell and houses all of the cell’s
genetic information. Usually, a cell
has a single nucleus that contains all
of its DNA molecules, but some
(such as skeletal muscle cells) have
more than one nucleus.
The nucleus protects the cell’s DNA
while controlling all other cellular
activities, such as cell division,
growth, protein production, and cell
death.

31. MITOCHONDRIA
Cells need energy to power their
biochemical reactions, and most of that
energy is released by
mitochondria. Mitochondria are the site of
respiration and the ‘powerhouses’ of cells,
pumping out energy which is then stored
in ATP (adenosine triphosphate). ATP
molecules are the energy currency of cells
and are used to fuel all the other activities
of the cell.

32. )
The endoplasmic reticulum is a network of membranes
inside a cell, and its main functions are to process and
transport new materials. There are two types of
endoplasmic reticulum; the rough ER, and the smooth ER.
The rough ER is studded with ribosomes, giving it a
bumpy or ‘rough’ appearance. It folds and tags newly-
synthesized proteins before transporting them to
wherever they are needed in the body. The smooth ER
does not have ribosomes attached to it and is instead
involved in hormone and lipid synthesis.

33. The DNA molecules housed in the
nucleus also contain blueprints for all
of the proteins produced by a cell.
These blueprints are ‘read’ and
interpreted by ribosomes, which are
the site of protein production in plant
and animal cells. Ribosomes produce
proteins by assembling amino acid
sequences according to the
instructions contained in the genetic
code. The resulting polypeptide
chains are then folded into specific
primary, tertiary, or quaternary 3D
structures by other cell organelles.

34. Once newly-synthesized substances
have left the ER, they are sent to the
Golgi apparatus. This is a series of
flatted, membrane-bound sacs that
packages and distributes substances to
the outer cell membrane, where they
either become part of the lipid bilayer
or leave the cell.

35. It is a jelly-like substance that fills the interior space of
cells. It is mainly composed of water, but also contains
salts, enzymes, and other organic molecules. The
cytoplasm surrounds and protects the organelles of the
cell and is where many cellular processes (such as
protein synthesis and glycolysis) take place.

36. Lysosomes are small, spherical organelles
that are packed full of digestive enzymes.
Their key function is to break down and
recycle unwanted material for the cell,
such as old cell parts or invading bacteria
and viruses. Lysosomes also play an
important role in apoptosis
(AKA programmed cell death).

37. Plasma Membrane
All cells are surrounded by a cell
membrane, which consists of a
semipermeable phospholipid
bilayer. The cell membrane controls
which substances enter and leave
the cell, and also separates the
interior of the cell from its external
environment.

38. CELL WALL
It is defined as a rigid, external layer that is
specifically designed to provide structural
support and rigidity. It also keeps the interior
components of the cell intact and safe from the
external environment. he main function of the cell
wall is to provide structural strength and support,
and also provide a semi-permeable surface for
molecules to pass in and out of the cell.

39. Networks of fibers that
are scaterred throughout
the entire cytoplasm and
interconnecting some
organelles.
