THIS IS A POWERPOINT PRESENTATION OF CELL STRUCTURE AND FUNCTION THAT CAN BE USE FOR DEMO TEACHING IN SECONDARY SCHOOL LIKE JUNIOR HIGHSCHOOL AND SENIOR HIGHSCHOOL APPLICATION FOR DEPED, THIS CAN BE USE BY EVERYONE AS THIS POWERPOINT PRESENTATION HELPED ME A LOT WHILE DOING MY DEMO TEACHING, I AM HOPING THAT EVERYONE WILL BE ABLE TO UTILIZE THIS MATERIAL AND USE THIS AS THEIR POWERPOINT PRESENTATION FOR THEIR DEMO TEACHING, THIS PRESENTATION INCLUDES PLANTS AND ANIMAL CELLS THE MAJOR ORGANELLES AND SUBCELLULAR ORGANELLES OF A CELL

1. ANIMAL CELL

2. Review
*EUKARYOTIC
*PROKARYOTIC

3. Motivation
 I have a cell but I don’t know its parts and function
 COULD YOU HELP ME???

4. Find the
Missing piece??

5. INTRODUCTION TO ANIMAL CELL
Three main parts of
a Eukaryotic Cell:

6. Cell Membrane

7. CELL MEMBRANE
Function
• Cell membrane is a complex barrier separating
every cell from its external environment.
• This "Selectively Permeable" membrane regulates
what passes into and out of the cell.
• The cell membrane is a fluid mosaic of proteins
floating in a phospholipid bilayer.

8. CELL MEMBRANE

9. Cytoplasm
Function
• Everything within the cell membrane which is
not the nucleus is known as the cytoplasm.
• Cytosol is the jelly-like mixture in which the
other organelles are suspended, so cytosol +
organelles = cytoplasm.
• Organelles carry out specific functions
the cell.

10. CELL MEMBRANE
CYTOPLASM

11. Endoplasmic Reticulum

12. Nucleus
Function
• The nucleus is normally the largest
organelle within a Eukaryotic cell. But it is
NOT the ‘brain’ of the cell!!
• The nucleus is surrounded by a double
membrane called the nuclear envelope,
which has many nuclear pores.
• The nucleolus are where ribosomes are
synthesised.

13. CELL MEMBRANE
CYTOPLASM
NUCLEUS
DNA

14. Ribosomes
• Ribosomes are not surrounded by a
membrane.
• Ribosomes are the site of protein synthesis
in a cell.
• They are the most common organelles in
almost all cells.
• Some are free in the cytoplasm (Prokaryotes);
others line the membranes of rough
endoplasmic reticulum (rough ER).

NUCLEUS

RIBOSOMES

17. Endoplasmic Reticulum
Function
• The primary function of the
ER is to act as an internal
transport system, allowing
molecules to move from
one part of the cell to
another.

RIBOSOMES

20. Golgi Body
Function
• The Golgi apparatus is
the processing,
packaging and secreting
organelle of the cell
• works closely with the
smooth ER, to modify
proteins

22. LYSOSOMES
• Lysosomes are small spherical organelles
that enclose hydrolytic enzymes within a
single membrane.
• Lysosomes are the site of protein digestion –
thus allowing enzymes to be re-cycled when
they are no longer required.
• They are also the site of food digestion in
the cell, and of bacterial digestion in
phagocytes.

24. MITOCHONDRIA
• Mitochondria are found scattered
throughout the cytosol, and are relatively
large organelles (second only to the
nucleus)
• Mitochondria are the sites of aerobic
respiration, in which energy from organic
compounds is transferred to ATP. For this
reason they are sometimes referred to as the
‘powerhouse’ of the cell.
