Sexual and Asexual Reproduction - Mom created questions from lesson 3 of your book

What mulitcellualr eukaryote reproduces by budding?

Hydras

Tell me how a starfish reproduces.

Organisms such as starfish reproduce asexually by regenration. Even a small part of the starfish can grow into a new organism.

What is sexual reproduction?

Sexual reproduction is reproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents.

True or false: Bacteria reproduce by binary fission.

True

True or false: Reproduction involves various kinds of cell division.

True

True or False: Some organisms reproduce by cell division.

True. In prokaryotes, which include bacteria and archaea, asexual reproduction happens by cell division.

True or false: New potato plants can grow from tubers.

True. New potato plants can grow from tubers.

What does re- mean?

re- means again

What does -ion mean?

-ion means act or process

What is asexual reproduction?

Asexual reproduction is reproduction that does not involve the union of sex cells and in which one parent produces offspring that are genetically identical to the parent.

What is a spore?

A spore is a specialized cell that can survive harsh conditions. Both prokaryotes and eukaryotes can form spores. Spores are produced asexually by one parent. Spores are light and can be carried by the wind.In the right conditions, a spore develops into an organism, such as a fungus.

Asexual or sexual? Which is quick?

Asexual is quick.

Asexual or sexual? Doesn't need a partner.

Asexual reproduction does not need a partner.

What are some details of asexual reproduction?

Asexual reproduction is when one organism produces one or more new organisms that are identical to itself. Most single celled organisms and some mulitcellualr organisms reproduce asexually. The organism that produces the new organism is called a parent. Each new organism is called an offspring. In asexual reproduction the parent transfers all of its genetic material to the offspring; menaing the offspring are identical to the parent. they may only differ if a genetic mutation happens.

How do dandelions usually reproduce? Asexually or sexually?

Dandelions usually reproduce asexually.

What is budding?

During budding, an organism develops tiny buds on its body. A bud grows until it forms a new full-sized organism that is genetically identical to the parent. Budding is the result of mitosis. Eukaryotes such as single celled yeasts and multicellualr hydras reproduce by budding.

True or false: Hydras reproduce by spores.

False. Hydras reproduce by budding.

True or False: Reproduction requires two parents.

False. In asexual reproduction, one organism produces one or more new organisms that are identical to the original organism.

True or False: Offspring of two parents always look like one of their parents.

False. Sexual reproduction increases genetic variation. Offspring have different traits that improve the chance that at least some of the offspring will survive. Offspring may have a trail that the parents do not have.

True or false: Spores cannot survive long periods of time in harsh conditions.

False. Spores CAN survive long periods of time in harsh conditions.

What is fertilization?

Fertilization is the union of a male and female gamete to form a zygote.

Tell me about sexual reproduction.

Most multicellular organisms can reproduce sexually. In sexual reproduction, two parents each contribute a sex cell to the new organism, Half the genes in the offspring come from each parent. So, the offspring are not identical to either parent. Instead, they have a combination of traits from each parent.

Can an individual organism live forever?

No. An individual organism does not live forever.

Asexual or sexual? Which increases chance of survival in changing environments?

On organism that can use both asexual and sexual reproduction increases the chance of survival in changing environments.

What does produce mean?

Produce means to make.

What lets genetic information be transferred to new organisms?

Reproduction

What are advantages of using both asexual and sexual reproduction?

Some organisms can use both types of reproduction. For example, when conditions are favorable, many plants and fungi will reproduce asexually. Doing so lets them spread quickly and take over an area. When the environment changes, these organisms will switch to sexual reproduction. This strategy increases the chance that the species will survive. Because of genetic variation, at least some of the offspring may have traits that help them make it through the environment change.

What is parthenogenesis?

Some organisms, such as aphids, reproduce asexually by parthenogenesis...which is when a female produces young without fertilization.

Tell me how tapeworms reproduce.

Tapeworms can reproduce asexually by fragmentation. Each segment of the worm can become a new organism if it breaks off of the worm.

What does the survival of any species depend on?

The ability to reproduce.

True or False: New plants can grow from parts of a parent, such as roots and stems.

True. Some plants are able to reproduce asexually by vegetative reproduction which is made possible by mitosis. New plants may grow from stems, roots, or leaves.

What single celled eukaryote reproduces by budding?

Yeasts

Fill in the blank: An advantage of ______________________________ reproduction is the ability to reproduce quickly.

asexual

Fill in the blank. Prokaryotes reproduce by ________________________.

binary fission

Fill in the blank: A benefit of asexual reproduction is that it is ____________________________.

fast

Fill in the blank: Male and female sex cells join during _________________________________.

fertilization

Fill in the blank: Sexual reproduction increases genetic _____________________________________.

variation

What are advantages of using asexual reproduction?

Asexual reproduction has many advantages. First, an organism can reproduce very quickly. Offspring are identical to the parent. So, it also ensures that any favorable traits the parent has are passed on to offspring. Also, a parent organism does not need to find a partner to reproduce. Finally, all offspring-not just females-are able to produce more offspring.

How do organisms reproduce asexually?

Organisms reproduce asexually in many ways. In prokaryotes (which include bacteria and archaea), asexual reproduction happens by cell division. In eukaryotes (which include single celled and multicellular organisms), asexual reproduction is a more involved process. It often involves a type of cell divsion called mitosis. Mitosis produces genetically identical cells.

What are advantages of using sexual reproduction?

Sexual reproduction is not as quick as asexual reproduction. Nor does it produce as many offspring. However, it has advantages. First, it increases genetic variation, Offspring have different traits that improve the chance at least some offspring will survive. This is especially true if the environment changes. Offspring are not genetically identical to the parent. so, they may have a trait that the parents do not have, making them more likely to survive.

Asexual or sexual? Which produces genetic variation?

Sexual reproduction produces genetic variation. (note: asexual may differ from parent if a genetic mutation occurs).

Asexual or sexual? Requires complex structures.

Sexual reproduction requires complex structures.

Describe the genetic makeup of the offspring of asexual reproduction.

Since the parent transfers all of its genetic information to the offspring for asexual reproduction, the offspring produced are identical to their parents.

What is vegetable reproduction?

Some plants are able to reproduce asexually by vegetable reproduction. Mitosis makes vegetable reproduction possible. New plants may grow from stems, roots, or leaves. Runners are aboveground stems from which a new plant can grow. Tubers are underground stems from which new plants can grow. Plantlets are tiny plants that grow alongside the edges of plant's leaves. They drop off the plant and grow on their own.

What is binary fission?

Binary fission is the form of asexual reproduction in prokaryotes. It is a type of cell division. During binary fission, the parent organism splits in two, producing two new cells. Generally, the new cells are exactly like the parent cell.

What does the word 'reproduction' mean in the following sentence? Flowers are plant organs that are used for reproduction.

The word reproduction in the sentence means the act of making another plant.....making another organism.

Picture a baby wolf and its mother in your head. How is the baby wolf similar to its mother?

They have the same type of fur. They each have four legs. There are many similar things you can see between a baby wolf and its mother.

Tell me about fertilization.

Usually, one parent is male and the other parent is female. Males produce sex cells called sperm cells. Females produce sex cells called eggs. Sex cells are produced by a type of cell division called meiosis. Sex cells have only half of the full set of genetic material found in body cells. A sperm cell and an egg cell join together in a process called fertilization. When an egg is fertilized by a sperm cell, a new cell is formed. this cell is called a zygote. It has a full set of genetic material. the zygote develops into a new organism. The zygote divides by mitosis, which increases the number of cells. the increase in cells produces growth. You are the size you are today because of mitosis.

Fill in the blank. The offspring of asexual reproduction are genetically _____________________ to the parent organisms.
