Looking Inside Cells
Inside A Cell
• Organelles - tiny cell structures that carry out a
specific function within the cell.
Plant Cells Vs Animal Cells
• Plant cells contain a cell
wall & chloroplasts.
• Plant cells contain one
large vacuole, it is the
largest organelle in a
plant cell.
• Animal cells contain
lysosomes.
• Animal cells contain
many small vacuoles.
• The largest organelle
in the animal cell is
the nucleus.
Cell Membrane
• The semi-permeable
membrane (allows only
certain things in and out)
that encloses the
contents of a cell.
• Found in all cells.
• Known as the security
wall
Cell Wall
• The rigid, outermost layer of a plant cell.
• A plant’s cell wall helps to protect and support
the cell, making it square.
Chlorophyll
• The green pigment found in the chloroplasts of
plants that is necessary for the production of
plant food during photosynthesis.
Chloroplasts
• Only found in plants.
• A small oval green bit of protoplasm that
contains chlorophyll and is the location of
photosynthesis.
Cytoplasm
• The gel like material that surrounds the
organelles.
• Found in all cells
Endoplasmic Reticulum
• Organelle in the cytoplasm that moves
materials around in a cell, is made up of folded
membranes; can be rough or smooth.
Golgi Bodies
• Golgi body is the cell’s mail room.
• Organelles that package cellular material
(proteins) & transport them within the cell or out
of the cell.
Lysosomes
• The organelle that contains enzymes to
break down or digest organic compounds
and old organelles.
Mitochondria
• very tiny rod-like or string-like structures that
occur in nearly all cells of plants and animals,
and that process food for energy.
• Known as the powerhouses of the cell, mostly
found in the muscle cells to give them energy.
Nucleolus
• small spherical body in the nucleus of a cell,
consisting of protein and RNA.
The Nucleus
• The part of a cell that controls growth &
reproduction.
• The control center of the cell.
Ribosome
• Small structure on which cells make their own
proteins.
• Protein Factories
• Found in all cells
Vacuoles
• A membranous enclosure within a cell that
contains substances.
• The storage centers of the cell.
• Plant:
Animal:
Bacterial Cells
Draw a picture and label all parts in the list at the end of
ppt.!
Bacteria Cells
• Flagellum
Movement
• PiliAttaches bacteria
to surfaces.
Bacteria Cells
• Plasma Membrane
It helps transport substances including removal of
wastes from the body.
Plasma membrane acts as a semi permeable
membrane, which allows only selected material to
move inside and outside of the cell.
Bacteria Cells
• Capsule
It is used to stick cells together and works as a food
reserve.
It protects the cell from dryness and from
chemicals.
• DNA
Genetic material of the cell
Bacteria Cells
• Cytoplasm
Helps in cellular growth, metabolism &
replication.
• Cell Wall
Helps in providing support, mechanical
strength and rigidity to cell.
Bacteria Cells
• Ribosomes
They are the site of protein synthesis.
• Plasmids
Used to exchange DNA between the bacterial cells.
Are small circle of DNA
