1/ Reproduction in animals
In biology, sex cells are called g_________________.
_______________ contain and carry only ________ set of the parental chromosomes
(half of the genetic material), they are said to be ___________.
________________ is the fusion of the nuclei of the two haploid gametes to produce a
z_________ (i.e. the first cell obtained from fertilization). The _____________ will then
divide to form the _______________.
In land mammals, fertilization takes place ___________________, i.e. the sperm is deposited
____________ the female body.
In fish, fertilization takes place ___________________, i.e. the sperm is deposited ______
the eggs, _____________ the female body..
A/ Male reproductive system
Copy and label the diagram below + copy and complete the table (make both bigger!).
Part
Penis
Sperm duct
Testes
Function
(In addition, you can also glue if you want the diagram from the hand outs)
In males, the __________ is the male gamete. It is produced in the ______________
. It travels in the ___________ __________ before it reaches the _____________
which allows it to be released inside the _____________ of the female.
B/ female reproductive system
Copy and label the diagram below + copy and complete the table (make both bigger!).
Part
Vagina
Uterus
Oviduct (Fallopian
tubes)
Ovary
Function
(In addition, you can also glue if you want the diagram from the hand outs)
In females, the _______ is produced in the ______________. Once a month, an egg
is released in the _________ . It is in the _____________that the ovum meets the
sperm and that _____________________ can take place to form the z__________.
After the first division, the embryo travels down the oviduct until it reaches the
____________ where implantation (i.e. its burying into tissue) can take place.
2/ Reproduction in plants
Read book
Copy and label the diagram below + copy and complete the table (make both bigger!).
Part
Petal
Stigma
Ovary
Nectary
Anther
Function
P___________ is when a pollen grain is transferred from an ___________to a
_________.
After landing on the stigma, the pollen grain germinates, i.e. it grows a pollen tube which
eventually reaches the__________. The male gamete travels down the pollen tube to fuse
with the female gamete to form the ________ (Fertilisation)
