Sex & Asex Reprod.

Sexual and Asexual Reproduction

QuestionAnswer
After Mitosis the cell finishes dividing in a stage called what? Cytokinesis
What are made of segments called genes and contain the genetic information necessary for cell reproduction? Chromosomes
During which phase are chromatid pairs lined up in the center of the cell? Metaphase
What is the correct order of the stages of mitosis? Prophase, Metaphase, Anaphase, Telophase
What is not a form of asexual reproduction? Fertilization
The function of which structure is to form spindle fibers that will attach to the chromatids for the purpose of moving chromatids? Centrioles
In what stage do the chromosomes separate and move to opposite sides of the cells? Anaphase
In this final phase, new nuclear membranes form around the chromosome and the cytoplasm begins to separate. Telophase.
Mitosis produces two daughter cells with how many chromosomes? 46
During which phase are the duplicated chromosomes visible and the nuclear membranes begin to dissolve? The centrioles will also begin to move to the opposite ends of the cell. Prophase
What is asexual reproduction? Asexual reproduction is a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones. This type of reproduction is common among some single-cell organisms.
Advantages of Asexual reproduction No mate needed. Many offspring produced quickly
Advantages of Sexual reproduction Genetic variation in the offspring.
Disadvantage of Asexual reproduction No variation in the offspring
Disadvantage of Sexual reproduction Requires both sexes to participate.
What is sexual reproduction? Sexual reproduction is a way of reproduction of some animals and plants. Some protists and fungi also reproduce this way. Organisms that reproduce sexually have two different sexes: male and female.
Example of asexual reproduction binary fission
What are the similarities of sexual and asexual reproduction? Both involve at least one parent Both produce offspring Offspring are of the same species Offspring are able to reproduce themselves
What would most likely result if mitosis was not accompanied by cytoplasmic division? one cell with two identical nuclei
Which structures are not involved in asexual reproduction? setae
During mitosis, a double-stranded chromosome is attached to a spindle fiber at the centromere
Many unicellular organisms reproduce by the process of fission
Which is easier to break apart? Asexual is easier to break apart.
What is reproduction? Reproduction is defined as the production of individuals of the same species, that is the next generation of the species
Why is reproduction necessary? Reproduction is necessary for the continuation of the species. If there is no reproduction, the species will become extinct and die out.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
