The Amazing World Inside a Human Cell

By Alisa Machalek and Emily Carlson

Posted June 29, 2011

Let's take a quick trip inside to see how cells carry out their major tasks.

Imagine you've shrunk down to 3 millionths of your normal size and are now about 0.5 micrometers tall—way

smaller than a dust mite or the width of a hair strand. At this scale, a medium-sized human cell looks as big as

a football field.

Nucleus

From your new perspective, the cell's somewhat spherical nucleus catches your

attention. It looks about 50 feet wide. Occupying up to 10 percent of the cell's

interior, the nucleus is the most prominent organelle, or cellular compartment. It

contains the cell's genetic material, DNA, which guides the making of billions of

protein molecules that participate in nearly every cellular process.

Membranes

The double membrane that bounds the nucleus flows into the ribosome-studded rough endoplasmic reticulum

(purple). Proteins are processed and lipids are manufactured in the smooth endoplasmic reticulum (blue) and

Golgi apparatus (green). Credit: Judith Stoffer, jStoffer Medical Illustration.

Encasing the cell is a membrane with special gates, channels and pumps that let in or

force out selected molecules. The membrane protects the cell's internal

environment—a thick brew called the cytosol made of salts, nutrients and proteins

Instructions: Read the article The Amazing World Inside a Human Cell, and then answer the following questions.


Background Information

Read the introductory paragraphs, and answer the following questions in your own words. Use complete sentences, and provide textual evidence to support your answers.

How many cells does the human body have, and how many different types are there?



What does the author want readers to imagine as they begin reading? Why?


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.

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.



Using evidence from the text, describe the purpose of the cell membrane.



How do the two types of endoplasmic reticulum differ?



Using evidence from the text, describe the purpose of the Golgi complex.



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

Read each statement and decide if it is a fact (can be proven with evidence) or an opinion (personal belief).

Different cell types also have special duties, like building skin or bone, pumping out hormones, or making antibodies.



Animal cells are more interesting than plant cells.



Proteins are processed and lipids are manufactured in the smooth endoplasmic reticulum and Golgi apparatus.

Your liver is a vital organ that is responsible for breaking down toxins in your body, among other things. Your liver cells have a large amount of which organelle? Choose from the following.

A. Nucleus
B. Cell membrane
C. Cell wall
D. DNA/Genetic material
E. Ribosome
F. Lysosome
G. Chloroplast

Answers

Answer:

F. Lysosome

Explanation:

Lysosomes ,also called the 'Waste Disposals Of A Cell', are sac-like organelles that contain powerful digestive juices in them. They help in digesting worn out cells or foreign particles such as Toxins or Waste, that don't belong there. Their enzymes are so powerful that, when they burst [During a spontaneous change in cell metabolism], they digest the whole cell with them.

Does asexual reproduction involve the formation of gametes? Explain your answer

Answers

Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.

Answer:

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction, either from from a single cell or from a multicellular organism, inherit the genes of their single parent.

How does earth's position in space affect water on earth?

Answers

Answer:

The Earth's position affects the water because the sunlight from the sun can impact the temperature of the water. It heats the water ethics and the land around it. When the Earth is facing the moon (nighttime), it cools the ocean creating a soft reaction.

Explanation:

While Earth orbits the sun, the planet is simultaneously spinning on an imaginary line called an axis that runs from the North Pole to the South Pole. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun.

What is Reproduction?

Reproduction is the process of formation of new organisms which are similar to the parent organism or parent cell. Reproduction is the process which generally occurs through different methods in a living cell or an organism.

Reproduction is mainly of two types, which include Asexual and Sexual mode of reproduction. Asexual reproduction is the reproduction where only one organism is involved in the process and it does not need the formation of gametes or the sex cells and sexual reproduction results into the formation of organisms through the fusion of gametes from two different organisms.

An example of asexual reproduction is an amoeba which splits through the binary fission into two separate new daughter cells.

Therefore, the correct option is D.
