Total questions: 30
Worksheet time: 17mins
In reproduction, what do you mean by fertilization?
When a farmer puts manure on farmland
When a male and female gamete fused
When plants drop seeds onto the ground
All of the above
This is the primary function of the human male reproductive system?
It provides the site that is ready to host a fertilized egg
It produce and transport gamete
Nourishes and bear the embryo
It prevents the urine to transport out of the body
From the choices below, which statement pertains to sex gamete is correct?
Ova is an immature male gamete
Male sex gamete is to be released once a month
Spermatozoa is matured male gamete
None of the above
Considered to be the primary sex organ of male?
Prostate
Glans
Testes
Penis
Seminiferous tubules for male as (a) for female?
Which male structure do you think is homologous with female's clitoris?
Scrotum
Prostate gland
Penis
Epididymis
Which specific part of the female reproductive organ that thickens in preparation to host an embryo and shed if fertilization does not took place.
(a)
This also refers as the post- ovulatory phase or the secretory phase?
(a)
Considered as the masterminds of reproduction?
Hypothalamus and anterior pituitary gland
Hypothalamus and posterior pituitary gland
Anterior pituitary gland and Hippocampus
None of these
This controls the amount to be released by the LH and FSH?
(a)
This is one of the basic differences of spermatogenesis and oogenesis?
The mature ovum is haploid and the sperm is Diploid
Spermatogenesis involves mitosis and meiosis, but Oogenesis involves meiosis only
One mature ovum is produced in Oogenesis, and four mature sperm are produced in Spermatogenesis
The mature ovum is diploid and the sperm is haploid
How many chromosomes are carried by the matured human gametes?
1
23
46
92
This is the usual site of fertilization?
Ovary
Fallopian tube
Testes
Uterus
How many daughter cells are produced in meiosis I?
1
2
4
8
When does the first arrest in the formation of female sex gamete happened?
Mitosis
Meiosis 1
Meiosis 2
None of these
A female baby is born carrying?
a mature ova
a primary oocyte
a secondary oocyte
all of these
What is the end product of meiosis II?
2 diploid gametes
4 diploid gametes
2 haploid gametes
4 haploid gametes
Which of the following statements about female and male gametogenesis is incorrect:
While male meiosis is completed in days or weeks, female meiosis is delayed for months or years.
In oogenesis meiosis is initiated once in a finite cell population, while in spermatogenesis meiosis is continuously initiated in a stem cell population.
Male gamete differentiation occurs after meiosis ends, whereas in oogenesis this occurs earlier during the first meiotic prophase.
Male meiosis produces four gametes, whereas female meiosis produces only two.
The reason why spermatids are rested in the epididymis is?
To reduce the chance of infection from the enteric bacteri
To gain maturity and motility
To provide for a cooler temperature
To place sperm storage sites nearer the penis
This hormone will send positive feedback to the pituitary gland that will cause the LH and FSH to release it's peak and will eventually rapture the mature follicle?
(a)
Ovulation takes place in the ----- day of the usual menstrual cycle?
12th
14th
15th
None of these
What do you call the process of germ duplication?
Mitosis

Day 1-5
Day 7- 10
Day 10-14
Day 15- 28
Which hormone is responsible for the premenstrual syndrome?
LH
FSH
Estrogen
Progesterone
This is considered to be the last phase of mitosis?
Prophase
Anaphase
Telophase
Metaphase
Mature sperm will be released in the lumen in the process called?
Spermatogenesis
Spermacytogenesis
Spermiogenesis
Spermiation
A diploid cell can also be represented as?
(a)
At what cell division does the 2nd polar body produced?
Mitosis
Meiosis I
