Cell Structures and Functions
Scale
4- I am an Expert
I am able to, in detail,
describe the cell theory, the
characteristics that make up living
things and the structure and function of
a cell
I am able to apply this
understanding to another structure or
situation. Example – How the school
can be a cell
3 – I can do it!
I am able to describe the cell
theory, the characteristics that makeup
living things that the structures and
functions of a cell.
2 – I am almost there
I know the cell theory,
the characteristics of life and the
structures of a cell, but I struggle
in explaining them.
1 – I need help
With help, I am able to
explain the cell theory,
characteristics of life and the
structures and functions of a
cell.
Notes
A eukaryotic cell holds its genetic material
inside of the nucleus of the cell.
A prokaryotic cell does not have a nucleus, so
its genetic material is in the cytoplasm.
Multicellular – An Organism with more than
one cell
Unicellular – An Organism with only one cell
PLANT AND ANIMAL CELLS
Your Paper – 3 Columns
Cell Part Function Plant, Animal or
Both
Cell Theory:
• All organisms are made up of one or more cells.
• The cell is the basic unit of organization of all organisms.
• All cells come from other cells all ready in existence.
CELL WALL: PLANT
• Function:Gives the cell most of its support and structure
• A thick, rigid membrane that surrounds a plant cell
• PLANTS ONLY
CELL MEMBRANE
• Function:
Semi permeable,
allowing some
substances to pass
into the cell and
blocking others.
• Thin layer of
protein and fat that
surrounds the cell
BOTH PLANT AND
ANIMAL
Chloroplast
• Function:
Where
photosynthesis
takes place
• An elongated or
disc-shaped
organelle
containing
chlorophyll
• PLANTS ONLY
Cytoplasm• Function:
Where the
organelles are
located.
• The jellylike material
outside the cell
nucleus.
• BOTH
ENDOPLASMIC RETICULUM
• Function:
transports
materials through
the cell
• Rough ER is
covered with
ribosome's that
give it a rough
appearance
• BOTH PLANT AND
ANIMAL
Golgi Bodies• Function:
Golgi bodies are the
packaging house and
secreting organelles of
the cell.
• Are stacks of
membrane-covered
sacs that package and
move proteins to the
outside of the cell.
• BOTH PLANT AND
ANIMAL
Lysosome
• Function:
Where the digestion
of cell nutrients takes
place
• They contain
digestive enzymes
• ANIMAL ONLY
Mitochondria• Functions:
Where energy is released; Powerhouse
• Spherical to rod-shaped organelles with a double membrane
• Membrane is in-folded many times, forming a series of projections (called cristae)
BOTH PLANT AND ANIMAL
Nucleus:The Manager• Function:
Controls many of the functions of the cell
• Spherical body containing many organelles, including the nucleolus
• Contains DNA (in chromosomes)
• Surrounded by the nuclear membrane
BOTH PLANT AND ANIMAL
Ribosome's• Function:
Small structures in
the cytoplasm that
create proteins.
• Ribosome's are
either free floating
in the cytoplasm of
a cell or attached to
endoplasmic
reticulum in a cell.
BOTH PLANT AND
ANIMAL
Vacuole• Function:
Like your suitcase, a vacuole is a temporary storage space for the cell.
• Fluid-filled, membrane surrounded cavities inside a cell
• Fills with food being digested and waste material that is on its way out of the cell
1 in Plant- Several in Animal
Day 1: Ticket Out
1.What is the smallest level of organization?
2.What controls all functions for a plant and
animal cell?
3.What is one thing that the plant cell has that
the animal cell does not?
