LEARNING OBJECTIVES4. I know that cells are the basic unit of all life and I can describe the functions that cells/life forms must carry out.

5. I know that single-celled organisms have parts to help them carry out all of life’s functions.

7. I know that plant and animal cells have parts in common and parts that are different in order to carry out life functions.

8. I can use a diagram or model to explain the difference between plant and animal cells.

• Cells are the smallest unit of LIFE! They are the building blocks of LIVING things.

• No matter if an organism has ONE cell or many, they share the same basic parts.

CELLS

Inside the cell, are structures (parts) called ORGANELLES (means “little organs”)

Each

organelle has a certain function (job) to do.

***We are only learning about the basic organelles; there are others which you might hear about in the reading and activities but you will not be tested on those.

Fill in the Table as we go

• Cell part is given,• Write in any functions• Note the pictures that go with each

part

CYTOPLASMCELL PART JOB/FUNCTION Picture

CYTOPLASM

 

GEL- like material inside the cell. o Mostly watero The other

organelles “float” in cytoplasm

o “Cyto” means cello “-plasm” means

jelly 

CELL MEMBRANECELL PART JOB/FUNCTION Picture

CELL MEMBRA

NE

 

“GATEKEEPER”—controls what goes in and out of the cell. 

NUCLEUSCELL PART JOB/FUNCTION Picture

NUCLEUS

 

 Directs all cell ACTIVITIESo Contains

DNA (instructions for cell)

o Largest organelle

o “boss” of other organelles

MITOCHONDRIACELL PART JOB/FUNCTION Picture

MITOCHONDRIA

 

o  Releases ENERGY in the cell; “POWERHOUSE”

o Performs cellular respiration

CHLOROPLASTCELL PART JOB/FUNCTION Picture

CHLOROPLAST

 o Found in

PLANT CELLS only!!!

o Converts SOLAR (SUN) ENERGY into cell energy.

CELL WALLCELL PART JOB/FUNCTION Picture

CELL WALL

 oFound in plants ONLY!

oOUTER SUPPORT structure; made of cellulose.

VACUOLESCELL PART JOB/FUNCTION Picture

VACUOLES

 o Stores

WATER, food, and waste products. Usually larger in PLANTS.

• Cell Walls

• Chloroplasts

What are the two parts plant cells have that animal cells do not have?

Cells on the light microscope

Cells are Systems!

• Individual cells are SYSTEMS because they have PARTS that work together to do a certain JOB.

Cells are Systems!

• What are some INPUTS?Food, water, oxygen, light (plant

cells)• What are some OUTPUTS? waste, CO2, water, chemical/thermal

energy

 • Open or Closed? Why?• Open because MATTER (molecules)

can go IN/OUT of the cell membrane
