Meiosis worksheet

Cancer cells reproduce relatively quickly in culture. The polar bodies are not normally fertilized by sperm cells, and they typically undergo programmed cell death, or apoptosis, within 24 hours of being produced 2 2.

But the orientation could have equally well been flipped, so that both purple chromosomes went into the cell together.

Label the Phases of Meiosis

The process with which the cells divide is called cell division and there are two types: You will need to save the file and Meiosis worksheet it in PowerPoint to have the music play throughout.

Why will most of the cells you view be in interphase? Answer the questions on each page in your lab notebook or print this first page and answer direction on it. How long does it take for mitosis to complete? Show Michael Clark's "Mitosis". This may seem familiar from mitosis, but there is a twist.

At the end of meiosis I, only one of the two daughter cells continues down the egg cell pathway, while the other becomes a non-egg cell called a polar body.

Other spindle fibers elongate but instead of attaching to chromosomes, overlap each other at the cell center. Each chromosome attaches to microtubules from just one pole of the spindle, and the two homologues of a pair bind to microtubules from opposite poles.

These cells are the gametes, the sex cells, Meiosis worksheet and egg or ovum. For example, take a look the meiosis II diagram above, which shows the products of meiosis for a cell with 2.

Answer the questions as you read the introduction and view the slides. They have half the genetic material, because when they fuse during fertilisation, the genetic material will become diploid again. Cells of large organisms like us have the ability to differentiate and become specialised according to their function.

This is why mitosis is only visible in cells that are dividing, like the whitefish embryo and the onion root tip. For instance, in the diagram above, the pink version of the big chromosome and the purple version of the little chromosome happen to be positioned towards the same pole and go into the same cell.

Sister chromatids stay together. With each partnership, our goal is to strengthen teacher effectiveness, empower school leaders and increase student engagement.

Cytokinesis usually occurs at the same time as telophase I, forming two haploid daughter cells. To make the move from asexual to sexual reproduction, nature took a system by which parent cells reproduced simply by dividing asexual reproduction and altered it to allow two parent cells to combine to create offspring sexual reproduction.

Your task is to look at photographs of actual slides and identify the stages of mitosis. Microtubules then reorganize into a new cytoskeleton for the return to interphase. Answer the questions on each page in your lab notebook or print this first page and answer direction on it.

Notice how the nucleus has duplicated doubled. Remember that most cells you see will be in interphase, that's the cells "resting" state. Why is the whitefish used to study mitosis? Sexual reproduction with meiosis produces genetic variation within a species.

Answer the questions as you read the introduction and view the slides. However, when meiosis takes place during oogenesis, egg cell production, in human females, only one functional egg cell is made. The diagram below shows the stages of cells during mitosis and meiosis: Doing It On the Table " is and activity designed to help students to learn the critical distinctions between what happens to chromosomes during mitosis vs meiosis.

If your school has this program, creating your own maps is a good way to introduce vocabulary. Scientists will make slides of cells that should be undergoing mitosis in order to find a particular cell in any of the stages - prophase, metaphase, anaphase, telophase.
