5. Starter activity (5 mins.):
• What is the different between plants and bacteria cell
wall?
• Why animal and human cells do not have cell wall?
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
6. What is the big question
that we will answer?
• What are the structures and their functions in prokaryotic
and eukaryotic cell?
I can explore the structures of typical eukaryotic cell
and what functions each structure serves.
7. Lesson concept: main idea:
Manufacturing Energy:
• Manufacturing Energy:
• Ribosomes: are organelles that manufacture proteins.
• Unlike other organelles, ribosomes are not membrane-bound.
• Ribosomes are produced inside the nucleus in the nucleolus.
• There are two types of ribosomes: 1. free ribosome in the
cytoplasm and 2. fixed ribosome that attached to rER.
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
8. Lesson concept: main idea:
Manufacturing Energy:
• The endoplasmic
reticulum (ER): is a
membrane system
of folded sacs and
interconnected
channels that serves
as the site for
protein and lipid
synthesis.
• There are two types
of endoplasmic
reticulum:
• rough
• smooth
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
9. Lesson concept: main idea:
Organelles and Functions :
• Processing,
Transporting, and
Storing Molecules:
• Golgi apparatus: is a
flattened stack of
membranes that
modifies, sorts, and
packages proteins.
• Proteins are packaged
into sacs called vesicles,
which can fuse to the
plasma membrane and
release the proteins to
the environment.
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
10. Lesson concept: main idea:
Organelles and Functions :
• Processing,
Transporting, and
Storing Molecules:
• A vacuole: is a
membrane-bound
sac used for
temporary storage.
• Vacuoles store food,
enzymes, or waste.
• Vacuoles are found
only in plant cells.
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
11. Lesson concept: main idea:
Organelles and Functions:
• Processing,
Transporting, and
Storing Molecules:
• Lysosomes: are
vesicles that contain
substances that digest
excess or worn-out
organelles and food
particles.
• They also digest
bacteria or viruses that
invade the cell.
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
12. Lesson concept: main idea:
Comparing Cells:
• Plant cells have:
• Chloroplasts/chlorophyll
• Vacuoles
• Cell walls
• Animal cells have:
• generally do not have these
features.
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
13. Lesson concept: main idea:
Organelles at Work:
• Knowledge of organelles allows for an
increased understanding of cellular processes.
• Protein synthesis begins in the nucleus with
DNA.
• RNA and ribosomes leave the nucleus and
produce a protein on the endoplasmic
reticulum.
• Proteins produced in the ER are sent to
Golgi apparatus for packaging.
• Packaged proteins are delivered to other
organelles, where they serve a variety of
functions.
I can explore the structures of typical
eukaryotic cell and what functions each
structure serves.
