a polysaccharide that is used to synthesize cell walls, which protect cells and help maintain their shape (structure, plant or animal)
cellulose, plant
regulate cytoplasm composition, creates internal pressure, and stores cell compounds
central vacuole
Which organelles or structures are absent in plant cells?
centrosomes
make sugar by converting light energy into chemical energy
chloroplast
they are the sites of reactions that convert solar energy into chemical energy (chloroplasts or mitochondria)
chloroplasts
they contain the green pigment chlorophyll (chloroplasts or mitochondria)
chloroplasts
they have membranous sacs called thylakoids that are surrounded by a fluid called stroma (chloroplasts or mitochondria)
chloroplasts
long fibers of protein found in the extracellular matrix that provide structural support for cells (structure, plant or animal)
collagen, animal
Motor proteins provide for molecular transport of materials in cells by interacting with what types of cellular structures?
cytoskeletal structures
a dynamic network of fibers that can be quickly dismantled and reassembled to change cell shape and the position of cell components
cytoskeleton
membrane protein complexes that strengthen the adhesion between adjacent cells, like rivets, to protect against pulling forces (structure, plant or animal)
desmosomes, animal

eukaryotic
small channels that form across the plasma membranes of adjacent cells; especially important in intercellular communication (structure, plant or animal)
gap junctions, animals
modifies some packages proteins
golgi apparatus
Which organelle plays a role in intracellular digestion?
lysosome
The matrix contains enzymes that function in cellular respiration (chloroplasts are mitochondria)
mitochondria
their inner membrane has infoldings called cristae (chloroplast or mitochondria)
mitochondria
