Cellular Parts
S7L2b
Relate cell structure (cell membrane,
nucleus, cytoplasm, chloroplasts,
mitochondria) to basic cell functions.
Plant Cells
Only in Plant Cells
• Cell wall-rigid membrane
around plant cell; made of
cellulose and provides
shape and support
• Plastids (chloroplasts,
leukoplasts, chromoplasts)
-used in photosynthesis
and product storage; have
double membrane and
provide color and cellular
energy
Basic Cell Structure
• Cell membrane
• The thin flexible
boundary surrounding
the cell
• Cytoplasm
– The watery, jelly-like part
of the cell that contains
salts, minerals and the
cell organelles
• Genetic material
– the area of the cell
where the DNA is stored
– It regulates all the
cellular activities
Organelles
• Little organs
• Small, specialized cellular subunits
• Helps a cell to move molecules, create and
store energy, store information and perform
many other functions
• Different kinds of cells have different
organelles
Animal Cells
Animal Cells Only
• Cilia- short, hair-like
extensions on the
surface of some cells
used for movement
and food gathering
• Flagella- long, whiplike extension on the
surface of some cells
used for movement
Basic Cell Organelles for Plants & Animals
• Vacuoles – Spherical storage sac for food and water
• Cell membrane – membrane surrounding the cell that allows
some molecules to pass through
• Golgi bodies- flattened membrane sacs for synthesis,
packaging and distribution
• Mitochondria- rod-shaped double membranous structures
where cellular respiration takes place
• Endoplasmic Reticulum- folded membranes having areas with
and without ribosomes used for transport of RNA and
proteins
• Nucleus- control center of the cell; location of hereditary
information; surrounded by nuclear envelope
• Ribosomes- Structures that make proteins; found on ER in the
cytoplasm
• Lysosomes- Spherical sac containing enzymes for digestive
functions
