CHAPTER 6
CLASSIFYING LIVING
THINGS
Chapter 6
Ways That Living Things Perform
Functions
 Grow: Unicellular organisms- size of their cell
increases
 Multicellular organisms- # of cells
increases
 Develop: Ladybug larvae grow into a
pupae and then adults
 Use Energy:
 Autotrophs: Convert light or energy
into food
 Heterotrophs- obtain energy from
other organisms
 Respond to Stimuli: Octopus responds
to predators by releasing ink to protect
itself
What Do Living Things Need?
Sunlight/Energy(food)
 H20
 CO2 & O2
 Living Space
 Proper Temperature
 HW DUE 1/5: Re read pgs. 187-193.
 Choose ONE living thing. Choose ONE
life function-Write ONE paragraph
explaining how the function applies to
the organism. How are they related?

HOMEWORK 1/9
 In
your own words, define
PROKARYOTIC and
EUKARYOTIC
 Name the functions of the
following: cell membrane, cell
wall, nucleus, cytoplasm,
mitochondria, chloroplast

What are cells made of?
What do many egg cells look like?
Why is a microscope needed to view
most cells?
What would happen to a human’s cells if
the human becomes dehydrated?
Do you think each of the trillions of
cells that are a part of you are either
alive or once-living? Why?
WHAT ARE
LIVING THINGS?

Autotroph: organism that converts light energy into
usable energy
Habitat: specific environment where an organism lives
Heterotroph: organism that obtains energy from
other organisms
Macromolecule: Substance in a cell that forms from
joining many small molecules together
Unicellular: one- celled organism
Multicellular: an organism made of more than one cell

 A prokaryotic cell is:
 A human cell is prokaryotic
OR eukaryotic???
Identify the missing organelles
A - Cell membrane
B - Nucleus
C - Ribosome
D - ER
E - Mitochondria
F - Nuclear Membrane
Organelles & Functions
Cell membrane - protects the cell , controls what
comes in and out of the cell
 Nucleus - directs cell activities(BRAIN)
 ER (Endoplasmic Reticulum)- sends
messages(HIGHWAY)/where some ribosomes are
found
 Golgi Body – packages proteins to be delivered around
the cell(mailmen)
 Ribosome - makes proteins
 Mitochondria - produces energy(Powerhouse!)
 Lysosomes-Clean out waste in the cell (garbage men)
 Vacuoles- stores food, H2O, and O2 (warehouse)
 Cytoplasm- jelly-like substance in the cell

REMEMBER!
 PLANT
CELLS HAVE 2
ORGANELLES THAT AN
ANIMAL CELL DOES NOT:
CELL WALL AND CHLOROPLAST

MVCO! Most Valuable Cell Organelle
Choose any organelle and connect it to one of the 6
life functions:
Made of cells
Organized
Grow and develop
Respond to their environment
Reproduce
Use Energy
USE YOUR NOTES AND TEXTBOOKS TO
REFER TO ORGANELLES AND FUNCTIONS
MVCO

Example:
A
golgi body is related to
RESPONDING TO THE
ENVIRONMENT BECAUSE……
 Must
use COLOR and
DECORATION/ILLUSTRATION
Photosynthesis
Carbon Dioxide + Water (with sunlight
and chlorophyll)----glucose(sugar) +
Oxygen
 6CO2 + 6H20----- C6H12O6 +6O2
 Chlorophyll TRAPs energy from the sun
and converts in into chemical energy
 OCCURS ONLY IN PLANTS
 Why???? ONLY PLANT CELLS
HAVE CHLOROPLAST

Cellular Respiration
Glucose + Oxygen--- Water + Carbon
Dioxide + ATP(energy)
 C6H12O6 + 6O2-- 6H2O + 6CO2 +
ATP
 Takes in place in BOTH plant and
animal cells IN THE MITOCHONDRIA


****Mitochondria
breaks down
the sugar and releases energy!!!!!!
