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?
