Cell Structure

Which structure is responsible for breaking down sugar molecules in order to supply energy to the cell?

A

What is the main difference between a prokaryotic cell and a eukaryotic cell?

A eukaryotic cell has a nucleus, and a prokaryotic cell does not.

Which structure helps produce, process, and transport proteins within the cell?

B

Ranjeet is studying an unknown group of cells and finds that the cells have lysosomes. He concludes that the cell must be an animal cell. Is his conclusion correct?

No, because although lysosomes more common in animal cells, they are found in both plant and animal cells.

Which is true about plant and animal cells?

Plant and animal cells are eukaryotes.

Faraj took the following notes in science class. Which is the best title for these notes?

Ribosomes

A newspaper article states that plant cells are easily identified by the presence of large vacuoles. Which of these evaluations is correct?

The article is correct because although vacuoles are found in both plant and animal cells, they are larger in plant cells than in animal cells.

Saki is trying to explain why the endoplasmic reticulum is important. Which of these analogies for the endoplasmic reticulum would best help her with this explanation?

The endoplasmic reticulum is like a factory that helps produce, process, and transport bricks.

Bobby has labeled the following diagram of a cell. His science teacher tells him it is perfect except for one error. Evaluate the diagram and choose the option that describes how Bobby's diagram can be corrected.

This type of cell does not contain a nucleus.

Which correctly identifies the cells above?

X cells are animal cells, and Y cells are plant cells.

Sean is trying to decide if a cell is a plant or animal cell. He studies the cell and is able to determine the function of many of the structures in it. Which notable structure can help him identify the cell?

a structure that converts energy from sunlight into chemical energy—only plant cells have structures with this function

Bai is making a chart to compare the organelles found in plant and animal cells. Which could X be?

chloroplasts

Sabrina arrives late to science class. Her teacher is discussing organelles that convert energy from sunlight to chemical energy. Which organelle is the teacher talking about?

chloroplasts

A lab technician is trying to determine how a certain chemical affects a group of cells. When the chemical is added to the cells, the cells are unable to break down sugar and they die of starvation. What organelle does the chemical most likely attack?

mitochondria

In a Venn diagram, the separate circles contain characteristics unique to each item being compared, and the intersection contains characteristics that are common to both items being compared. Maggie is working on a Venn diagram to compare the structures found in plant and animal cells. Which can she place in the intersection?

mitochondria and endoplasmic reticulum
