James is making models of plant and animal cells using objects supplied by his teacher to represent organelles. For one cell, he will place the objects in a shoebox. First he fills a balloon with water and places it in the shoe box. He also drops a handful of marbles into the box.
Which statement most likely describes the structures he has represented so far?
He is making an animal cell. The box is the cell membrane, and the balloon represents the large vacuole. The marbles are the endoplasmic reticulum.
He is making a plant cell. The box is the cell wall, and the balloon represents the large vacuole. The marbles are the tiny ribosomes.
He is making a plant cell. The box is the cell wall, and the balloon represents the nucleus. The marbles are the centrioles.
He could be making either a plant or animal cell. The box is the cell wall, and the balloon represents the large vacuole. The marbles are the centrioles.
