3. CELL THEORY
CELL THEORY
The cell theory asserts that all
living things are composed of one
or more cells, and that cells are
the basic unit of structure and
function in organisms. This theory
has three main principles: all
living organisms are composed of
one or more cells, the cell is the
basic unit of life, and all cells
come from pre-existing cells.

4. CELL CYCLE
CELL CYCLE
The cell cycle is a series of events
that take place in a cell leading to
its division and duplication. It
consists of interphase (G1, S, G2)
and the mitotic phase (prophase,
metaphase, anaphase,
telophase). The cell cycle is
crucial for growth, repair, and
reproduction of organisms.

5. ORGANELLES
ORGANELLES
Organelles are specialized
structures within the cell that
perform specific functions.
Examples include the nucleus,
mitochondria, endoplasmic
reticulum, and Golgi
apparatus. Each organelle has
a specific role in maintaining
the cell's function and survival.

6. NUCLEUS
NUCLEUS
The nucleus is the control center
of the cell, containing the
genetic material (DNA) and
directing the cell's activities. It is
surrounded by a nuclear
membrane and contains the
nucleolus, where ribosomes are
produced.

Mitochondria
Mitochondria are known as the
powerhouse of the cell,
producing energy in the form of
ATP through cellular respiration.
They have their own DNA and
are thought to have originated
from ancient bacteria through
endosymbiosis.

RETICULUM
ENDOPLASMIC
RETICULUM
The endoplasmi c reticulum is
a network of membranes
involved in the synthesis of
proteins and lipids. It can be
rough (with ribosomes) or
smooth (without ribosomes),
and plays a crucial role in
protein folding and transport.

9. Golgi Apparatus
Golgi Apparatus
The Golgi apparatus is
responsible for modifying,
sorting, and packaging proteins
and lipids for transportation. It
consists of flattened sacs called
cisternae and plays a key role in
the secretion of cellular
products.

10. Understanding the cell theory, cell cycle, and
organelles is fundamental to comprehending the
building blocks of life. The intricate processes within
a cell and the specialized functions of organelles
contribute to the complexity and beauty of life.
