Proteins destined for extracellular release are packaged in specific vesicles. After packaging, the vesicles bud off and are stored in the cell until a signal is given for their release. When the appropriate signal is received they move towards the membrane and fuse to release their contents.

Once proteins have been produced at the ribosomes, what two organelles work together to aid in the secretion process described above?

• ribosome and ER

• Golgi apparatus and rough ER

• Golgi apparatus and lysosome

• mitochondria and rough ER

Plant and animal cells have a lot in common. Compare and contrast the two cells. Select the features that you find in BOTH types of cells.

• membrane, nucleus, cytoplasm

• membrane, chloroplasts, nucleus

• cell wall, cell membrane, nucleus

• cell membrane, cell wall, chloroplasts

• Golgi bodies

• mitochondria

• endoplasmic reticulum

Why don't animal cells need chloroplasts?

• Animals do not make their own food.

• Animal cells make their own chlorophyll.

• Animal cells collect sunlight another way.

• Animals use photosynthesis to make their own food.
