1. All life forms are made from one or more cells.
2.Cells only arise from pre-existing cells.
3.The cell is the smallest form of life.
Body system level:
the digestive system
Organ level: the
stomach
Tissue level:
layers of tissue in
the stomach wall
Cellular level:
a cell in the
stomach lining
Chemical level:
a molecule in the membrane
that encloses a cell
Organism level:
the whole body
• NO NUCLEUS
• Small, simple
• A prokaryotic cell is enclosed by a
plasma membrane and is usually
encased in a rigid cell wall
–The cell wall may be covered by a sticky capsule
–Inside the cell are its DNA and other parts
• Grow & reproduce
•EX. E. coli (bacterial cells)
•HAVE A NUCLEUS &
MEMBRANE-BOUND
ORGANELLES
•Grow & reproduce
•Some live as single cells
•Examples: Plants, animals, fungi, etc.
Function: provide support and protection for the
cell; allows water, oxygen, carbon dioxide and
other things to pass through
FOUND ONLY IN PLANT CELLS
Function: controls most cell
processes an contains hereditary
info of DNA; has chromatin
which forms chromosomes during
mitosis
Location: near the center of the
cell
Found in all EUKARYOTIC cells
Function: Location where
ribosomes are made
Location: WITHIN the nucleus.
Found in all EUKARYOTIC cells
Description: DNA
bound to proteins
that is visible within
the nucleus
Location: WITHIN
the nucleus.
Description: Condensed
chromatin, distinct,
thread-like structures
containing genetic
information.
Location: WITHIN the
nucleus.
Found in all EUKARYOTIC cells
