Text-dependent Questions

Use quotes from the text or summarize the text in your own words to answer the following
questions or prompts. Use complete sentences, and provide textual evidence to support your
answers. Note: The first one has been completed for you.
3. What material does the nucleus contain? What is the purpose of this material?
The nucleus contains "the cell's genetic material, DNA." DNA makes protein molecules to
help with almost every cellular process.
4. Using evidence from the text, describe the purpose of the cell membrane.
5. How do the two types of endoplasmic reticulum differ?
6. Using evidence from the text, describe the purpose of the Golgi complex.
7. Based on this excerpt, summarize the job of mitochondria.
Excerpt: "About the size of pickup trucks from where you're floating, the organelles
called mitochondria convert energy from your food into adenosine triphosphate, or ATP,
to power biochemical reactions. A typical cell burns through 1 billion molecules of ATP
every 1 to 2 minutes."

Answer 1

Explanation:The purpose of the cell membrane is to "enclose the cell, separate its internal environment

from its external environment, and regulate the traffic of molecules in and out of the cell."

The two types of endoplasmic reticulum differ in their physical appearance and function. The rough

endoplasmic reticulum has ribosomes attached to it and is involved in the synthesis and

processing of proteins. The smooth endoplasmic reticulum lacks ribosomes and is involved in

lipid metabolism, calcium storage, and detoxification.

The Golgi complex's purpose is to modify, sort, and package proteins and lipids from the endoplasmic reticulum for transport to their final destinations inside or outside the cell.

Mitochondria convert energy from food into ATP to power biochemical reactions. They burn through 1 billion molecules of ATP every 1 to 2 minutes, indicating that they are responsible for generating energy for the cell.
