Question

jeremy 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 shoebox. he also drops a handful of marbles into the box. which statement most likely describes the structures he has represented so far? o 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. o he is making a plant cell. the box is the cell wall, and the balloon represents the large vacuole. the marbles are the ribosomes. o he is making a plant cell. the box is the cell wall, and the balloon represents the nucleus. the marbles are the centrioles. o 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.

Explanation:

Plant cells have a cell wall, a large vacuole, and may or may not have centrioles. Animal cells have a cell - membrane, no cell wall, and centrioles. The box represents a rigid structure like a cell wall which is characteristic of plant cells, and the large vacuole is also a feature of plant cells. The presence of centrioles could indicate either type, but the cell - wall and large vacuole strongly suggest a plant cell.

Answer:

He is making a plant cell. The box is the cell wall, and the balloon represents the large vacuole. The marbles are the centrioles.
