Conditioned stimulus

Classical conditioning is a learning procedure in which a biologically potent stimulus paired with previously neutral stimulus. This pairing will cause a response  that can be the same as the potent stimulus. This is done repeatedly for an organism to elicit a conditioned response to the previously neutral stimulus that was paired to the active stimulus. The dog salivates due to the idea that  food is related to the sound of the bell.

nata0808 [166]

Answer:

plant cell

Explanation:

The Golgi apparatus is a cell organelle responsible for modifying, sorting and packaging proteins and lipid molecules into vesicles (i.e., Golgi vesicles) for their delivery to targeted cell sites. A plant cell can contain many -even hundreds- of Golgi apparatus. During cell division of plant cells, Golgi vesicles combine at the metaphase plate in order to form a structure called phragmoplast. Subsequently, the cell plate formed by phragmoplast vesicles grows from the center to the cell walls. Finally, the vesicle membranes fuse to form a plasma membrane that divides the plant cell into two cells.
