Core Content
 SC: 3.4.1, SC 3.4.2, and SC 3.4.3
I can
 I can tell my parents the differences
between a plant and animal cell.
 I can tell my parents about the parts of the
animal and plant cell.
On your desk

 Pencil
Today’s Agenda
 Bell Ringer
 Rules (Classroom)
 Notes: Copy ALL notes into your notebook
Notes:
 What is an organism?
– Is a living thing
Examples: frogs, bears, you!
 Cell -is the smallest unit of living things that can
carry out the basic processes of life.
 Unicellular— one celled
– Single cell that carries out its life processes
– Example: ameoba
Life processes
 These processes: growing, responding to an environment,
reproducing and getting food.
 Multicellular—
– Made of more than one cell
– Include frogs, trees, and you!
– You have eye cells, skin cells, heart cells, etc….
Plant vs. Animal Cells

 Nucleus
 Cytoplasm
 Vacuole
 Cell membrane
 mitochondria
Plant Cell
 Nucleus
 Cytoplasm
 Vacuole
 Cell membrane
 Mitochondria
 Cell Wall
 Chloroplast

Cell parts
 Nucleus–
– the cell’s control center (brain)
 Cytoplasm
– Made mostly of water
– Organelles float in the cytoplasm
– Occupies the region from the nucleus to the cell
membrane
 Vacuole
– Membrane covered structure used for storage
– Can store water, food and wastes
 Cell membrane—
– Flexible wrapping around the outside of the cell.
– Wraps around the cell (like your skin wraps
around you)
– Controls what materials move into and out of
the cell
Plant’s Only
 Cell wall
– Is stiff structure outside the cell membrane
– Provides strength and extra support for the
plant
 Chloroplast
– A green structure where the energy from
sunlight is used to produce food for the plant.
– Green because—they contain a chemical called
chlorophyll.
 Able to use the energy in sunlight
 Found mainly in the cells of the leaves and
 Stems of plants
Is chloroplast in all plants?
 Plant cells that lack chloroplast are not
green.
 Can you think of any?
How are cells organized?
