Total questions: 25
Worksheet time: 26mins
What is a difference between mitosis and meiosis? Mark ALL that apply!
Mitosis occurs in the cytoplasm and Meiosis occurs in the nucleus.
Mitosis results in diploid (2n) daughter cells and Meiosis results in haploid (n) daughter cells.
Mitosis results in 2 daughter cells and Meiosis results in 4 daughter cells.
Mitosis makes somatic (body) cells and Meiosis makes gametes (egg and sperm cells).
Examples of cells that undergo MEIOSIS are
bacterial cells
animal cells (such as skin cells) and plant cells (such as leaf epidermis cells)
sexual reproduction cells called gametes
Cells that contain 2 sets of chromosomes are called _________ (2n).
diploid
haploid
triploid
polyploid
Cells that contain only ONE set of chromosomes are called ________ (n).
diploid
polyploid
triploid
haploid
If a Diploid cell has 20 chromosomes, how many will a haploid have?
20
10
15
40
Meiosis is responsible for:
Staying the same
Similar cells
Creating identical cells
Genetic Diversity
In Meiosis, the chromosomes go through crossing over, this leads to:
Genetic variation
Identical daughter cells
To replication of genes
