12

Secondary vesicles travel from the Golgi to the cell membrane and release the proteins that need to be secreted.

3

Vesicles traveling from the smooth ER can carry lipids and carbohydrates to the cell membrane.

10

A food vacuole (phagosome) forms when food is pulled into the cell from the cell membrane.

11

After lysosome enzymes break down food in the secondary lysosome, usable material is released into the cytoplasm and waste travels back to the memebrane to be released.

9

Lysosome enzymes in a vesicle bud off of the golgi's trans face to form the primary lysosome and later travel to fuse with a food vacuole and form the secondary lysosome.

6

The golgi apparatus is made of several distinct sacs that are not connected.

1

The nucleus has two membranes that make up it's nuclear envelope. The outside of membrane is continuous with the rough endoplasmic reticulum's membrane.

2

The rough endoplasmic reticulum has a series of folds dotted with ribosomes.

4

The smooth endoplasmic reticulum does not have ribosomes on the outside. The smooth ER's membrane is continuous with the rough endoplasmic reticulum's membrane.

8

Vesicles travel along the Golgi sacs from the cis face to the trans face, as proteins are sorted and modified.

7

Vesicles travel along the Golgi sacs from the trans face to the cis face, recycling membrane and lipids, to keep each golgi sac the size it needs to be.

5

Vesicles travel from the rough ER to the golgi apparatus, carrying proteins to be modified and stored.
