During
cytokinesis, the cytoplasm divides and …….daughter cells produced.
a) two
b) three
c) four
d) five
Explanation:in mitosis only two cells produced with same number of chromosomes
Meiosis:
Meiosis is a type of
cell division that reduces the number of chromosomes in the parent cell by half
and produces four
gamete cells. This process is required to produce egg and
sperm cells for sexual reproduction.
Meiosis takes
place to produce…….
a) body cells
b) blood cells
c) sex cells
d) all of these
Sex cells or germ cells are also called…….
a) sperm
b) gametes
c) ovum
d) somatic cells
Explanation:A gamete is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism.
Which of the following is/are the male sex cells?
a) sperms
b) ova
c) eggs
d) both b and c
Explanation:sperm, also called spermatozoon, plural spermatozoa, male reproductive cell, produced by most animals. With the exception of nematode worms, decapods (e.g., crayfish), diplopods (e.g., millipedes), and mites, sperm are flagellated; that is, they have a whiplike tail.
Which of the following is/are the female sex cells?
a) sperms
b) ovum
c) eggs
d) both b and c
Explanation:a female gamete : macrogamete especially : a mature egg that has undergone reduction, is ready for fertilization, and takes the form of a relatively large inactive gamete providing a comparatively great amount of reserve material and contributing most of the cytoplasm of the zygote.
