Cells


Organism: An individual living thing. It can
be made up of one cell (unicellular) or up to
billions of cells (multicellular).
Cell: “Little room” that run on energy from
the sun (sugars), they are alive because they
take in nutrients, water and get rid of waste.
They reproduce too.

Cells have structures (organelles) inside that help
them carry out the characteristics of life:
Nucleus: “Brain/Library of the cell”, it has all of the
directions to control the activities of the cell and
reproduces.
Mitochondria: “Powerhouse of the cell” it produces
energy from sugars
Endoplasmic Reticulum: Passageways through the
cytoplasm of the cell to carry nutrients and wastes
through the cell.

Ribosome: Protein factories of the cell (cell needs proteins
to grow and repair cell parts)
Vacuoles: Storage tanks for the food, water or waste in
the cell. Plant cell vacuoles are large, animal cells are
small.
Lysosomes: “Clean up crew” for wastes in the cell. In
animal cells.
Chloroplast: In plants only. It captures the sun’s energy
and makes sugars through photosynthesis.
Cell wall: In plant cells only. It is the stiff outer layer that
protects and supports the cell.
Cell Membrane: Outer covering of the cell that protects it
and allows certain items to enter and exit.


Split your paper into 2 sections, 1 will be an animal
cell, the other will be a plant cell.
Draw and color each and include the following cell
structures and a definition of what they do for the
cell:
Nucleus
Mitochondria
 Endoplasmic reticulum
Ribosome
 Vacuole
Lysosome
 Cell membrane
Cell wall
 Chloroplast

Today we are going to look at:
A plant cell: Elodea
An animal cell: Cheek cell
For both cells you will be making a wet mount slide
