A student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. Why would this procedure fail to produce a prokaryotic cell?

A
The cell would lack genetic information.
B
The cell would lack the structure that is needed to produce energy.
C
The cell would lack the structure that is needed to protect the cell’s organelles.
D
The cell would lack control over materials that move into and out of the cell.

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.

A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified?

A
The cell is prokaryotic because it contains ribosomes.
B
The cell is prokaryotic because it contains mitochondria.
C
The cell is eukaryotic because it contains ribosomes.
D
The cell is eukaryotic because it contains mitochondria.

5

Which cell structure serves the stated function in both eukaryotic and prokaryotic cells?

A
nucleus: stores genetic material
B
cytoplasm: protects cell structures
C
ribosomes: regulate cell processes
D
DNA: surrounds cell contents
6

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why?

A
mitochondria, because they rely on the ER as an energy source
B
ribosomes, because they receive proteins made by the ER
C
Golgi apparatus, because it packages proteins received from the ER
D
cytoplasm, because it relies on the ER for structural support
