both

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

Proteins that will be secreted from the cell are likely to be found enclosed spaces bounded by membranes of the _______ system.

endomembrane

Comparing eukaryotic and prokaryotic cells - Lysosome

eukaryotic

Comparing eukaryotic and prokaryotic cells - Mitochondria

eukaryotic

Comparing eukaryotic and prokaryotic cells -Nucleolus

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

they are the sites of reactions that convert chemical energy from food molecules to ATP (chloroplasts or mitochondria)

mitochondria

Which structure is common to plant and animal cells? (mitochondrion, wall made of cellulose, chloroplast, or centriole)

mitochondrion

produces chemical energy that can power the cell

mitochondrion

plant cell

strong, protective structure made from cellulose fibrils

plant cell wall

small channels between cells that are otherwise surrounded by walls; enable movement of water and solutes between cells (structure, plant or animal)

plasmodesmata, plant

Which statement correctly describes an endomembrane function?

products of the ER are usually modified during their transit from the cis to the trans region of the Golgi apparatus

Comparing eukaryotic and prokaryotic cells - Nucleoid

prokaryotic

ribosome

Drag the labels on the left onto the diagram of the animal cell to correctly identify the function performed by each cellular structure. (list alphabetically)

synthesizes lipids, assembles ribosomes, defines cell shape, produces secretory proteins, modifies and sorts proteins, generates ATP, digests proteins
