Paragraph Styles 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. The membrane protects cell s permanent environment A thick brew which is the cytosol from salt, nutrients, and protein. 5. How do the two types of endoplasmic reticulum differ? 6. Using evidence from the text, describe the purpose of the Golgi complex. 1. 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." Fact vs. Opinion
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
