Asexual Reproduction quiz

What is asexual reproduction (AR)

The formation of a new individual that has the same genetic information as its parent.

What are four functions of life?

1. Reproduction

2. Movement

3. Growth & development

4. Response to stimuli

Four phases of mitosis IN ORDER

Prophase: first stage, chromosomes become visible, membrane disappears

Metaphase: chromosomes are pulled by spindle fibres

Anaphase: there are now twice as many chromosomes in the cell

Telophase: Nuclear membrane reappears, spindles disappear

AR advantages

• large colonies can out-compete other organisms for nutrients and water

• large numbers of offspring reproduce quickly

• species can survive if the # of predator increases

AR disadvantages

• offspring compete for food and space

• extreme temperatures can wipe out entire colonies

• negative mutations can destroy offspring

Sexual Reproduction

A process where a single cell divides twice to produce four cells containing half the og amount of genetic information.

SR advantages

• Decreased genetic disorders

• Increased evolutionary fitness

• Increased genetic variability

SR disadvantages

• it takes time and effort to find a mate

• Fewer offspring are produced

• Not always successful

Describe a parenting objective from one of the four “reproductive strategies”

Sand scorpion: the newborn babies quickly crawl into their moms back to stay until theyre big enough to leave the burrow.

How do flowering plants rely on the environment?

• Many plants rely on water or wind to carry the sperm

• Advanced plants rely on insect help

• To have the sperm reach the egg, plants will use the environment to somehow get it done for them

What is cancer?

Cancer is the uncontrolled growth and division of cells. There is a malfunction in the body in knowing when to start and stop mitosis.

Why is cancer dangerous?

The likelihood of cells becomes mutated. They will keep reproducing at a high rate, causing all of this energy being devoted to these cancer cells making normal cells to suffer.

Methods of seed dispersal

1) wind

2) water

3) animals

4) bursting
