What does it mean to make new organisms of the same species?

To reproduce.

100
How many parents are needed for asexual reproduction to occur?
Only 1 parent cell is needed
100
How many parents are needed for sexual reproduction to occur?
2 parents (1 male, 1 female) are needed
100
Name an advantage of asexual reproduction?
Only needs one parent, happens very quickly, offspring are clones of parents, successful characteristics are guaranteed, requires less energy and time
100
Name a disadvantage of asexual reproduction.
Lack of variation, organisms are more susceptible to diseases, organisms are less likely to adapt to new environments
150

What is pollen used for?

Used to pollinate flowers. Aides in reproduction. 

150
Are the daughter cells exactly the same as or different from the parent cells?
Exactly the same (identical copies)
150
Are the offspring exactly the same or different from the parents? Why?
The offspring are different because they get characteristics from the father and the mother.
150
Name an advantage of sexual reproduction.
Lots of variation can occur, Variations can help organisms to survive in new environments, Help to protect entire populations from being killed by diseases
150
Name a disadvantage of sexual reproduction.
Organisms/Cells take a longer time to mature, Must have a mate (2 parents), Gametes (sperm/egg) can be lost, Takes more energy and time
200

What type of reproduction do most mammals (humans and animals) use?

Sexual Reproduction 

200
Name the four types of asexual reproduction.
Binary Fission, Budding, Fragmentation/Regeneration, Vegetative Propagation
200
What is fertilization?
When a male cell (sperm) joins with a female cell (egg/ovum) to create a zygote/new organism
200
Which type of reproduction can occur very quickly?
Asexual Reproduction
200
Which type of reproduction takes more time and energy? Why?
Sexual Reproduction because it takes more time for cells to mature and organisms to be fully formed (made of many cells)
250

What type of reproduction do viruses and bacteria use?

Asexual Reproduction

250
Which type of asexual reproduction do most bacteria use?
Binary Fission
250
What is the difference between internal fertilization and external fertilization?
Internal fertilization happens inside the body, while external fertilization happens outside of the body.
250
Which type of reproduction creates organisms with a lot of variations? Why
Sexual Reproduction because the offspring get characteristics from both parents, rather than just one parent.
250
Which type of reproduction lacks variation?
Asexual Reproduction because the cells are exactly the same as the original parent cell.
300
What do we call the new organism or organisms made during reproduction?
Daughter Cells or Offspring
300
Which type of asexual reproduction do plants generally use?
Vegetative Propagation
300
What happens during pollination?
During pollination, pollen from the anther (male) is moved to the pistil (female), where it will travel down to the egg to fertilize it. This causes a seed to form.
300
Which type of reproduction creates organisms that would have an easier time adjusting to a new environment? Why?
Sexual Reproduction because there are more variations amongst the organisms created.
300
Which type of reproduction is more susceptible to disease (more likely to die of disease)? Why?
Asexual Reproduction because the cells are all the same and are more likely to die if a disease spreads.
