sexual reproduction
regeneration
spindle fibers

If a diploid tomato cell has 24 chromosomes, how many chromosomes will the tomato's sex cells have?
12
6
24
48
What is the mathematical relationship between the number of chromosomes and the number of homologous pairs?
There is no mathematical relationship between the number of chromosomes and the number of homologous pairs.
The number of chromosomes is related directly to the age of the organism, so the number of homologous pairs changes.
There is only one chromosome in each homologous pair.
There are one half as many homologous pairs as there are chromosomes.
Some berry plants send out runners over the soil and new berry plants grow from the runners. What form of asexual reproduction does this represent?
vegetative reproduction
budding
fission
zygote formation
What is the division of the cytoplasm called?
cytokinesis
fission
meiosis
cellular reproduction

It produces new offspring that have the same genetic information as the parent.
It involves the joining of a sperm cell and an egg cell.
It occurs only in plants.
It requires a male parent and a female parent.
Why is regeneration of skin tissue or liver tissue in humans not considered to be asexual reproduction?
Skin and liver tissue have only one half the number of chromosomes as children.
Regeneration is a type of sexual reproduction.
Only plants can reproduce by regeneration.
A new organism is not formed from part of the parent.
If a cell that has six chromosomes goes through meiosis, how many chromosomes will the daughter cells have?
1
3
6
9
What name is given to two chromosomes which contain the same genes?
heterologous
homologous
mitotic
