Question

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?(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.

Answer 1

not sure if you still need help with this

he used a shoebox for the outermost part of the cell. shoe boxes have solid walls, so it's more likely this representes a cell wall, rather than a membrane, which means this is a plant cell. This narrows us down to choices B + C. Now, thinking about what organelles a plant cell has, and how one might represent them - which one do you think is a more accurate description of what he's doing?
