Questions and Correct Answers
Advantages: no need for a partner, reproduce quickly, and repairs and grows other
organisms.
Disadvantages: cell becomes smaller at beginning, one bad gene causes everyone to
have that bad gene, large organism cannot reproduce, and can give you cancer.
✅Explain the advantages and disadvantages of asexual reproduction.
Advantages: offspring will have two parents, produce more offsprings, genetic variation,
and adapt easier.
Disadvantages: slower, have to find a mate, and cannot be used for growth and repair.
✅Explain the advantages and disadvantages of sexual reproduction.
Crossing over is when mother and father chromosomes trade information. It occurs
during prophase. It it such an important event because it creates genetic diversity
(makes us different). ✅What is crossing over? When does it occur? Why is it such an
important event?
Spermatogenesis produces sperm and all the cells are used. Oogenesis produces egg
cells and only one cell is used. ✅Compare and contrast spermatogenesis and
oogenesis.
In animal cells, cytokinesis involves a cleavage furrow, which pinches the cell in two. In
plant cells, vesicles formed by the Golgi fuse in the center forming a membrane bound
wall called a cell plate. ✅Describe the difference between cytokinesis in animal cells
and plant cells.
Mitosis and meiosis are both produced by one round of DNA replication. The four
daughter cells resulting from meiosis are haploid and genetically distinct. The daughter
cells resulting from mitosis are diploid and identical to the parent cell. ✅What are
similarities and differences between mitosis and meiosis?
Independent assortment is the random assignment of maternal and paternal
chromosomes. Its outcome is diversity in genetic combinations. ✅What is independent
assortment? What is its outcome?
The steps of the cell cycle are G1, S, and G2. In G1, a cell grows. In S, the cell
continues to grow as it copies its chromosomes. In G2, the cell that continues to grow
as it copies its chromosomes then grows more as it completes preparations for cell
division. ✅List the steps of the cell cycle and briefly explain what happens in each.
