Next week's lesson is designed to introduce
the plant and animal cell along with all of its parts that allow it to
function. They will identify the parts of the cell and describe each part’s
job.
Cells are the building blocks for
various organisms’ systems (organs, structural walls, skin, leaves,....)
All living things are made up of
cells. The structures of different types of cells are related to their
functions.
Animal cells and plant cells have
features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria
and
ribosomes.
Plant cells also have a cell wall,
and often have chloroplasts and a permanent vacuole.
Animal and Plant Cells
Function of cells which animal and
plant cells have in common
Nucleus
Contains genetic material, which
controls the activities of the cell
Cytoplasm
Most chemical processes take place
here, controlled by enzymes
Cell
membrane
Controls the movement of substances
into and out of the cell
Mitochondria
Most energy is released by
respiration here
Ribosomes
Protein synthesis happens here
Plant cells also have extra parts:
Cell
wall
Strengthens the cell
Chloroplasts
Contain chlorophyll, which absorbs
light energy for photosynthesis
Permanent
vacuole
Filled with cell sap to help keep
the cell full of material
