Meiosis – Alternate Assignment to U4 L4, “Modeling Meiosis Portfolio”
Read pages 323-329 in your Biology text and answer the following questions. This worksheet models an active reading strategy which you can use when reading material for any of your classes.You are required to provide answers to the prompts shown in italics.
Before Reading
Set a Purpose for Reading
What specific information will you be learning about?Meiosis.
Why do you think it is important to know about this? It Is probably important to know about this because it involves cells and everyone has cells in their body.
Preview the Text
Look at the headings, figures, captions under figures, bold-faced print and other graphics.Describe one figure you think will be helpful or important:One figure that would be helpful or important would be the headings. Because then you get an idea of what the paragraph is about.
Activate Background Knowledge
Think about what you already know about the content of what you will read.What topics did we cover during our previous lessons that might help you? Some topics that we covered that would help me would be the ones about cells. Meiosis has a relation to cells, I figured that out by reading some of the headings in the lesson.
Predict
Think about what you will learn in this section, what words may be used, or what information the text mightcontain.List one question you expect to be able to answer after reading this section: What is Meiosis?
During Reading
Reread
When problems occur, return to the beginning of a sentence or paragraph and read it again.List one sentence or paragraph you chose to read again: “The diploid cells of most adult organisms contain two complete sets of inherited chromosomes and two complete sets of genes.”
Predict and Confirm
Ask yourself, "What word do I expect to see?", "What do I think will happen next?", "Did that makesense?", or "Am I finding the answers to my questions about this topic?"
Skip, Read On, and Go Back
Sometimes you can skip an unfamiliar word and read to the end of the sentence or paragraph,thinking about what would make sense. Then, using the context, go back and reread to try todetermine the word.List one term, along with its definition, that you were a bit confused by at first glance: Haploid: Cells that only contain a single set of chromosomes, and therefore a single set of genes. Also means “One set”.
Connect Background Knowledge to the Information in the Text
Think about what you already know about the subject and the kind of material you are reading. Thinkabout how the information is similar to what you already know about the topic, event, or person. What does this reading make you think of? It makes me think of cells because Meiosis is a process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
What did you already know? After reading that, I had already knew what homologous and diploid meant.
Stop and Review
If you are reading a longer text, stop and think about what you have read about in the chapter/textso far or whatinformation has been given. You may wish to stop after each paragraph to review.
After Reading
Retell and Summarize
Tell someone about what you learned or write a review of the information presented.In a few sentences, summarize the important points from this section in your book: Most diploid cells have two complete sets of inherited chromosomes and genes. Meiosis occurs in two different phases with sub phases. The difference between Meiosis and mitosis is that mitosis doesn’t change the chromosome number of the original cell. But, in meiosis it reduces the number by dividing it in half, or reducing the number by half.
Use a Graphic Organizer
Create a flow chart, concept map, Venn diagram, or other way to show what was included in whatyou read.Fill in the table below after reading the section “Comparing Meiosis and Mitosis” on page 327.
Key Concept / Why is this important?How is meiosis different from mitosis?
Meiosis reduces the chromosome number by half and mitosis does not normally change that number of the original cell. / This is important to know because then you know the terms differences with eachother since the word is so similar.
In mitosis, when the two sets of genetic material separate, each daughter cell receives one complete set of chromosomes. In meiosis, homologous chromosomes line up and then move to separate daughter cells. / This is important to know because it explains or gives a worded example of the terms meiosis and metosis so you can get a better example of the meaning and what it does.
Mitosis does not normally change the chromosome number of the original cell. This is not the case for meiosis, which reduces the number by half. / This is important because then you can know the difference between the two and know what they both do to the chromosome number.
Draw Conclusions
Think about what predictions you made before and during reading. Look back and think about whatyou have read. Consider how the information read relates to what you already knew about the topic.
Were your questions answered? Yes.
What questions do you still have about the subject?None.
Reread
Reread the text or a section of the text to help you understand it better.What section(s) did you reread? I reread the section “phases of meiosis” because I wanted to get a better understanding of each phase that goes on.
Discuss and Respond
If possible, talk with someone about what you have read (Learning Coach or parent for example). Ask each other questions. Look back at the book tocheck your understanding.Who did you discuss this material with?My mom.
Write to Support Understanding
Write about what you have read, describing what it made you think of or what you learned.Summarize what you have learned by writing at least 3 paragraphs below:
