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….

Both
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?
