Sexual vs Asexual Reproduction

Multiple Choice

What is the difference between sexual and asexual reproduction?

• Asexual produces genetically different offspring. Sexual produces genetically identical.

• Sexual produces offspring with fewer chromosomes. Asexual produces more.

• Sexual produces genetically different offspring. Asexual produces genetically identical.

• Sexual reproduction is quicker than asexual.

Asexual reproduction

• Only involves ONE parent

• Offspring are clones (Identical) to the parent

• The offspring has the same DNA as the parent

Asexual reproduction

• Type of reproduction by which offspring arise from a single organism or one parent

• Produced via mitosis

• Offspring inherit genes/DNA from only 1 parent

• The offspring are genetically identical (clones) to the parent

Dropdown

Offspring reproduced asexually are ​

Select answer

to their parents.

Multiple Choice

Asexual reproduction- especially in bacteria is similar to which type of cell division ?

• Mitosis

• Meiosis

• Osmosis

• Hocus Pocus

Binary Fission

Binary Fission- is when 1 bacteria or simple organism splits into 2.

A fully grown parent cell splits into two halves, produced 2 identical cells

Only occurs in single celled organisms

Budding

• Offspring grows out of the body of a parent

• Offspring still identical to the parent

• Example is showing the budding of a hydra

Fragmentation

• Body of the parent breaks off

• Each piece can grow into a new FULL organism

• Tissue regrows due to regeneration

  • Regeneration is when a piece of a damaged organism can regrow

• Examples are Sea stars (starfish)

Match

Match the following type of ASEXUAL reproduction to the organism

• Sea Stars

• Bacteria

• Hydra

Fragmentation

Binary Fission

Budding

• Fragmentation

• Binary Fission

• Budding

Multiple Choice

Budding, Binary Fission and Fragmentation are all examples of

• Sexual Reproduction

• Asexual Reproduction

Sexual reproduction

• Sexual reproduction involves offspring created from TWO parents.

• One parent produces male gametes and one parent produces female gametes.

• Gametes are produced during meiosis.

Pollination

Pollination is a form of sexual reproduction found in flowering plants.

Pollen (sperm cells ) will fertilized the ovary (egg cells) of flowers to produce new plants

Multiple Choice

The process used to create sperm and egg cells (can be in plants or animals)

• meiosis

• mitosis

Multiple Choice

Egg and Sperm cells are also known as

• genetically diverse

• clones

• gametes

Advantages of Asexual Reproduction

• Rapid population increase

• Only 1 parent- does not need to find a mate

• Fast and Energy Efficient

Disadvantages of Asexual Reproduction

• NO genetic diversity

• Species may only be able to live in 1 habitat

• Species MAY be more vulnerable to diseases and environmental changes

Multiple Choice

Which is an Advantage of asexual reproduction

• Fast and energy efficient

• Need to find a mate

• May be vulnerable to diseases

• No genetic diversity

Multiple Choice

What is a disadvantage to asexual reproduction

• No genetic diverstiy

• Fast and energy efficient

• Only needs 1 organism

• Can grow population rapidly

Advantages of Sexual Reproduction

Creates genetic diversity

Species MAY be more resistant to environmental changes

Species MAY be more resistant to new diseases

Disadvantages of Sexual Reproduction

Takes more time and energy to find a mate

Takes energy to make sex cells

Individuals who cannot find a mate end up NOT reproducing

Multiple Choice

A disadvantage of sexual reproduction is that it is

• more time consuming than asexual reproduction

• creates less diversity than asexual reproduction

• uses less energy than asexual reproduction

Multiple Choice

An Advantage of sexual reproduction is

• less energy is used

• greater genetic diversity in the species

• it is more efficient than asexual reproduction
