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.
16. CELLS
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.
17.
18.
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. They are found and attached to
the endoplasmic reticulum or
free floating in the cytoplasm
(free ribosomes). They use the
RNA synthesized by the
nucleolus in making specific
amino acid. They are referred as
protein factories
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, single-membrane
compartment containing powerful
hydrolytic enzymes. It is also referred as “
suicide bag” of cell. It is 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.
37. Also called as plasma membrane,
flexible and elastic that composed
of double layers of phospholipid,
proteins, carbohydrates and
steroids.
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. The 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.
49. Plant Cells
Plant Cell
Plant cells are eukaryotic cells that vary in several fundamental
factors from other eukaryotic organisms. Both plant and animal cells
contain a nucleus along with similar organelles. One of the
distinctive aspects of a plant cell is the presence of a cell wall
outside the cell membrane.
50.

53. Animal Cells
• Animal cells are typical of the eukaryotic cell, enclosed by a
plasma membrane and containing a membrane-bound nucleus
and organelles. Unlike the eukaryotic cells of plants and fungi,
animal cells do not have a cell wall. This feature was lost in the
distant past by the single-celled organisms that gave rise to the
kingdom Animalia.
