2. OVERVIEW STUDY GUIDE (RPS)

3. LEARNING OBJECTIVES
• Student is able to describe about cell.
• Student is able to identify cell’s organelle and Its function
• Student is able to identify the differences between animal and plant cells.
• Student is able to describe biochemical activities happened in the cells (week
3)

4. WHAT IS CELL ?
• Basic Building Blocks of all the living things
• The basic structural, functional, and biological unit of all known living
organisms.

5. CELL ORGANELLES

6. NUCLEUS
The nucleus is the most prominent organelle
in the cell. This small organelle is separated
from the cytoplasm by two membranes, the
inner and outer membrane. The nucleus
contains the genetic material (DNA) which
will code the genetic information to order the
biochemical process in the cell.

7. CELL MEMBRANE
Thin membrane that surrounds every
living cell, delimiting the cell from the
environment around it.
The cell membrane, therefore, has two
functions: first, to be a barrier keeping the
constituents of the cell in and unwanted
substances out and, second, to be a gate
allowing transport into the cell of
essential nutrients and movement from
the cell of waste products.

8. ENDOPLASMIC RETICULUM
Endoplasmic reticulum (ER) is a continuous
membrane system that forms a series of flattened
sacs within the cytoplasm of eukaryotic cells and
serves multiple functions, being important
particularly in the synthesis, folding,
modification, and transport of proteins.
2 types of ER : Smooth ER and Rough ER

9. RIBOSOM
Ribosome is present in large numbers in all
living cell and serves as the site of protein
synthesis. Ribosomes occur both as free
particles in prokaryotic and eukaryotic cells
and as particles attached to the membranes of
the endoplasmic reticulum in eukaryotic
cells.

10. GOLGI APPARATUS
Membrane-bound organelle of eukaryotic cells that
is made up of a series of flattened, stacked pouches
called cisternae.
The Golgi apparatus is responsible for transporting,
modifying, and packaging proteins and lipids into
vesicles for delivery to targeted destinations. It is
located in the cytoplasm next to the endoplasmic
reticulum and near the cell nucleus.

11. LYSOSOME
Lysosome, subcellular organelle that is found in nearly all types
of eukaryotic cells (cells with a clearly defined nucleus) and that
is responsible for the digestion of macromolecules, old cell
parts, and microorganisms.
Lysosomes contain a wide variety of hydrolytic enzymes (acid
hydrolases) that break down macromolecules such as nucleic
acids, proteins, and polysaccharides.

12. VACUOLE
Vacuole A space within a cell that is empty of
cytoplasm lined with a membrane and filled with
fluid.
The large central vacuoles often found in plant cells
enable them to attain a large size without
accumulating the bulk that would make metabolism
difficult.

13. MITOCHONDRIA
Mitochondrion, membrane-bound organelle found in
the cytoplasm of almost all eukaryotic cells (cells with
clearly defined nuclei), the primary function of which
is to generate large quantities of energy in the form of
adenosine triphosphate (ATP).
Mitochondria are unlike other cellular organelles in
that they have two distinct membranes and a unique
genome and reproduce by binary fission these features
indicate that mitochondria share an evolutionary past
with prokaryotes (single-celled organisms).

14. CHLOROPLAST
Chloroplast, structure within the cells of
plants and green algae that is the site of
photosynthesis, the process by which light
energy is converted to chemical energy,
resulting in the production of oxygen and
energy-rich organic compounds.
