Which organelle modifies cell products, packages them for distribution, and then may turn into vesicles and bubble off the surface of the cell? (simple question i know but i forgot it)

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
