What are the parts of a cell?
How do they function?
What Are the differences between plant and
animal cells?
Animal Cells
Nucleus: Regulates all cell activity,
produces ribosome’s
Nuclear membrane
Mitochondria: Site of chemical
reactions, have their own DNA
Lysosomes: Digest excess or wornout organelles, food particles, and
engulfed viruses or bacteria.
Materials:
Microscope
Slides
Iodine
Slip cover
Onion/cheek tissue
Procedure:
A. Prepare a wet mount slide of onion root/
cheek cells
Remove onion root from onion stem/ cotton
swab cheek.
Place the root/cheek on a glass slide.
Place a drop of iodine stain on your
onion/cheek tissue.
Place cover slip over stained tissue.
Golgi apparatus: The Golgi
apparatus processes and packages
macromolecules, such as proteins
and lipids.
Cell membrane: Regulates passage
of materials in and out of the cell
Smooth Endoplasmic Reticulum:
Rough Endoplasmic Reticulum:
Cytoplasm: Gelatinous substance
inside cell Membrane but outside the
nucleus, contains organelles.
Plant Cells
Plasmodesmata: Tubes between
cell wall
Cell membrane: Regulates passage
of materials in and out of the cell
Vacuole: Storage, (water)
Conclusion:
The plant cell has a more angular cell and all the
cells are joined together.
The animal cells have a more circular shape that is
a little less defined.
