Meiosis
51 of 84
Contains pollen grains which produces the male gametes
Anther
52 of 84
Is the stalk that supports the anther
Filament
53 of 84
The end bit that the pollen grains attach to
Stigma
54 of 84
Rod-Like section that supports the stigma
Style
55 of 84
Contains the female gametes
Ovary
56 of 84
The transfer of pollen from an anther to a stigma, so that the male gametes can fertilise the female gametes
Pollination
57 of 84
Pollen is transferred from the anther of one plant to the stigma of another plant
Cross-Pollination
58 of 84
The fusion of Gametes
Fertilisation
59 of 84
When seeds start to grow
Germination
60 of 84
A tube which carries sperm through the penis during ***********. Urine also passes through the urethra to exit the body
Urethra
61 of 84
Swells when filled with blood to make penis erect
Erectile Tissue
62 of 84
Where sperm is made
Testis
63 of 84
Produce the liquid added to sperm to make semen
Glands
64 of 84
Muscular tube that carries sperm from testis towards the urethra
Vas Deferens
65 of 84
Hangs behind the penis and contains the testes (Scrotum)
