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?
Answer
A
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.
B
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.
C
He is making a plant cell. The box is the cell wall, and the balloon represents the nucleus. The marbles are the centrioles.
D
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.
