Term
Photosynthesizing eukaryotes
Definition
Chloroplats are the photosynthesizing organelles of all
Term
the sun to the chemical energy of sugar molecules
Definition
Photosynthesis is the conversion of
Term
Compartments
Definition
Cholroplasts are partitioned into
Term
intermembrane space
Definition
Between the outer and inner membrane is a thin
Term
Thylakoids
Definition
Inside the inner membrane is a thick fluid called Stroma that contains Chloroplat DNa, ribsomes and many enzymes and a network of interconnected scas called
Term
stacked like poker chips. Each stack is called granum, where green chlorophyll molecules trap solar energy
Definition
In some regions thylakoids are
Term
DNA and Ribosomes
Definition
Mitochondria and chloroplasts have
Term
Prokarytic cells
Definition
the structure of this DNA and these ribosomes is very similar to that found in
Term
the endosymbiont theory
Definition
A theory that proposes that mitochondria and chloroplasts were formerly small prokaryotes and they began living within larger cells.
Term
Cytoskeleton
Definition

Network of interconnected protien filaments and tubules 

Extended from the nucleus to the plasma membrane 

Only in eukaryotes 

Maintains cell shape 

With motor protiens, allows and organelles to move

Term
three kinds of fibers
Definition
the cytoskeleton is composed of
Term

microfilaments 

Intermediate filaments 

Microtubles

Definition
the cytoskeleton s composed of three fibers
Term
microfilaments
Definition
support the cells shape and are involed in motnity
Term
Intermediate filaments
Definition
reinforce cell shape and anchor organelles.
Term
Microtubules
Definition
give the cell rigidity and act as tracks for organelle movement.
Term
cilia and flagella
Definition
move when microtubules bend
Term
locomotion, some cells of multicellular organisms have them for different reasons
Definition
while some protists have flagella and cilia are important in
Term
cilia
Definition
cells that sweep mucus out of our lungs have
Term
flagellated
Definition
Animal sperm have
Term
Cilia and Flagella
Definition

eukaryotes 

For movement of the cell or fluids past the cell 

Similar construction in oth 

9+2 pattern of microtubules 

Cilia shorter and more numerous than flagella
