Vocabulary
What does reproduce mean?
To make new organisms of the same species
How many parents are needed for asexual reproduction to occur?
Only 1 parent cell is needed
How many parents are needed for sexual reproduction to occur?
2 parents (1 male, 1 female) are needed
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
Name a disadvantage of asexual reproduction.
Lack of variation, organisms are more susceptible to diseases, organisms are less likely to adapt to new environments
What is homozygous?
Individual possesses two of the same alleles for a gene
Are the daughter cells exactly the same as or different from the parent cells?
Exactly the same (identical copies)
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.
Name an advantage of sexual reproduction.
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
What is heterozygous?
Individual possesses two different alleles of a gene.
Name the three types of asexual reproduction.
1. Binary Fission, 2.Budding, 3. Spores
What is sexual reproduction?
When a male cell (sperm) joins with a female cell (egg/ovum) to create a zygote/new organism
Which type of reproduction can occur very quickly?
Asexual Reproduction
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)
What is genetic continuity?
When a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell
Which type of asexual reproduction do most bacteria use?
Binary Fission
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.
Which type of reproduction lacks genetic variation?
Asexual Reproduction because the cells are exactly the same as the original parent cell.
What is genetic variation?
Individual with characteristics different from the others of the same kind.
Which type of asexual reproduction do hydra generally use?
Budding
Strawberry plants are capable of reproducing sexually or asexually. When they reproduce sexually, how do the offspring receive their genetic material?
A. They receive all of their genetic material from a single parent.
B. They receive half of their genetic material from each parent.
D. They receive the majority of the genetic material from the female plant.
B. They receive half of their genetic material from each parent.
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.
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.
