WHO DISCOVERED CELLS?
Robert Hooke 1665
English Physicist
First to observe cork and
their characteristic hexagonal
shape, using the first optical
microscope, which was
invented by him at that time
which he now called CELLS.
ROBERT HOOKE.
ROBERT HOOKE
o Published his observations
on tiny living organisms
which he named
animalcules.
o The first to observe under
his microscope the structure
of a red blood cell of
different animals as well as
Anton van Leeuwenhoek a sperm cell.
1676.
o He was able to compare
diverse kinds of plant
specimens under the
microscope.
o Indicated that there is a
common thing about them-
they are all composed of
cells, and inside the cell is a
dark dense spot which he Robert Brown 1831
termed as the NUCLEUS.

Three Basic Components
CELL STRUCTURE
NUCLEUS
The nucleus protects the DNA
and is an integral component of a
plant’s cell structure.
CELL STRUCTURE
CELL
ORGANELLES
Cells are composed of various cell
organelles that perform certain specific
functions to carry out life’s processes.
Nucleolus
The nucleolus is the site of
ribosome synthesis. Also, it is
involved in controlling cellular
activities and cellular reproduction
CELL

CELL
Chromosomes
Chromosomes play a crucial role in
determining the sex of an individual.
Each human cells contain 23 pairs of
chromosomes.
CELL
Endoplasmic Reticulum
The endoplasmic reticulum is
involved in the transportation of
substances throughout the cell.
CELL
Golgi Bodies
Golgi bodies are called the cell’s
post office as it is involved in the
transportation of materials within the
cell.
CELL
Ribosome
Ribosomes are the protein
synthesizers of the cell.
CELL
Mitochondria
The mitochondrion is called “the
powerhouse of the cell.” It is called
so because it produces ATP – the
cell’s energy currency.
CELL
Lysosomes
Lysosomes protect the cell by
engulfing the foreign bodies entering
the cell and help in cell
renewal. Therefore, they are known
as the cell’s suicide bags.
CELL
Chloroplast
Chloroplasts are the primary
organelles for photosynthesis. It
contains the pigment called
chlorophyll.
CELL
Vacuoles
Vacuoles store food, water, and
other waste materials in the cell.
