What is the primary reproductive organ in females

Ovaries

100

What is the name for male gonads?

Testis

100

Where does ovulation occur in the female and male reproduction system?

Ovaries and testes

100

What is the other term for the menstruation cycle?

Uterus cycle

Describe two ways in which flower is adapted for wind pollination

Any two from the following:

  • The stigmas are large / feathery (to catch pollen floating in the air); [1 mark]
  • The stigmas are exposed (to the wind); [1 mark]
  • The filaments are long (to catch floating pollen grains); [1 mark]
  • The anthers / stamens hang outside the flower structure (to catch floating pollen grains); [1 mark]
  • The anthers are loosely attached to the filament (so it can be blown off by the wind); [1 mark]
  • There are no / less / small petals (which would act as a wind break); [1 mark]

What are the two possible outcomes after ovulation?

Fertilization or menstruation

200

What features of the sperm cell allow them to move around in the fallopian tube?

Flagellum

200

What does follicle transform after releasing the eggs?

Corpus Luteum

200

Which hormones rise first during the menstruation?

Estrogen

Sexual reproduction results in seed formation in plants.

Describe three conditions required for seed germination

Three conditions needed for the germination of seeds are:

  • Oxygen; [1 mark]
  • Water / humidity / moisture; [1 mark]
  • (A suitable) temperature / warmth; [1 mark]
300

Where does fertilization happen in the female reproductive system, and what is produced as a result?

Fertilization happens in the fallopian tube, and a zygote is produced.

300

Where do sperm get mature?

Epididymis 

300

What happens to body temperature after ovulation?

Body temperature rises

300

Which hormone triggers the follicle?

Estrogen

An investigation was carried out on a plant species.  Plant 1 – Anthers removed; buds left open to the air. 
Plant 2 – Anthers untouched; paper bag tied tightly around each bud. 
Plant 3 – Anthers removed and paper bag tied tightly around each bud.  
Although all flowers later opened normally, only those on plant 1 produced seeds. This results shows that:  
A. only cross-pollination can take place.
B. only wind-pollination can take place. 
C. only insect-pollination can take place.
D. both self-and cross-pollination can take place.

What moves the egg towards the uterus, in the fallopian tube?

Cilia

400

What are the three glands in the male reproductive system that collects fluid?

Seminal vesicle, Prostate gland, and B-gland

400

Which two structures produces progesterone and when?

corpus luteum

placenta

400

Which hormone regulates menstruation?

Progesterone

Some plant species are self pollinated. 

Discuss the long term effects of self pollination on the evolution of the plant species.

Any four from the following:

  • Limited variation; [1 mark]
  • Offspring become homozygous (over time) / reference to inbreeding / limited gene pool; [1 mark]
  • Variation is due to mutation; [1 mark]
  • Low chance that mutations will be expressed; [1 mark]
  • Offspring will be well adapted to conditions near parent...; [1 mark]
  • ... if the environment does not change; [1 mark]
  • Limited opportunity for evolution if environment changes / will not be able to adapt to change in the environment / reference to disease in context (as a change); [1 mark]

What could possibly happen to the zygote when they don't reach the uterus?

Ectopic pregnancy

500

Which gland produces a fluid that neutralizes the acid/urine?

Bulbourethral glands (b-glands)

500

What could possibly happen when two eggs are produced through ovulation and fertilize with two different sperms?

Non-identical twins form
