18
Q

What are “Gametes”?

Study These Flashcards
A

gametes are reproductive cells that join together to create an organism!
- sperm cells are male gametes
- egg cells are female gametes
- egg and sperm cells are games.

19
Q

How does the sperm reach the egg?

Study These Flashcards
A
  1. an egg is released from an ovary and moves along the fallopian tube helped along by the cilia.
  2. sperm enter the vagina and travel through the cervix and uterus to the fallopian tube.
  3. A sperm reaches the fallopian tube and fertilises the egg.
  4. a fertilised egg= zygote.
20
Q

what is gestation?

Study These Flashcards
A

In all mamals, the time in the uterus from fertilisation until birth is known as gestation.

21
Q

what is a zygote

Study These Flashcards
A

fertilised egg cell

22
Q

what is an embryo.

Study These Flashcards
A

a developing baby before the emergence of organs (up to 8 weeks)

23
Q

what is a foetus.

Study These Flashcards
A

a developing baby after the emergence of organs until birth (after 8 weeks)

24
Q

The mother needs to give the foetus…

Study These Flashcards
A

nutrients
oxygen
protection

25
the mother needs to take away from the foetus...
carbon dioxide waste substances
26
what is the foetus protected by?
uterus and amniotic sac ( a liquid contained in a bag called the amnion)
27
what is the placenta important for in the womb?
responsible for providing oxygen and nurtients and removing waste substances such as carbon dioxide. it grows on the wall of the uterus and is joined to the foetus by the umbilical cord
28
Since the mother's and foetus' blood do not mix, what happens...
The placenta lets substances pass between two blood supplies e.g oxygen diffuse across MOM to FOETUS by PL CO2 diffuse across FEO to MOM by PL
29
After 9 months what hapoens during birth?
The cervix relaxes and the muscles in the wall of the uterus contract, pushing the baby out of the mother's body.
30
What is afterbirth?
When the baby is born, the umbilical cord is still connected so this needs to be cut. The placenta will then need to be delivered. This is called afterbirth.
31
What happens on day 1 of the menstural cycle?
The lining of the uterus sheds and leaves the body through the vagina this causes bleeding.
32
what happens on day 5-7 of the menstural cycle?
the bleeding stops and the lining of the uterus begins to re-grow. The linign is spngy and filled with blood. This will provide a deep layer for implantation is an egg IS fertilised.
33
What happens on day 14 of the Menstural cycle?
an egg cell is released from one of the ovaries- this is called ovulation.
34
Day 15-28 of the menstural cycle. What happens..?
is the egg is fertilised: it settles into thick lining- implantation if egg is not fertilised: egg dies and the lining of the uterus is maintained, waiting for a fertilised egg.
35
what is contraception used for
Contraception is used to prevent pregnancy
36
how does contraception work? the two different ways
contraception works by: 1. preventing sperm and egg cell meeting 2. preventing fertilised egg from implanting in the uterus.
37
how to stay healthy during preganancy 2 things TO DO and 2 things NOT TO DO
GOOD: healthy diet- baby receives essential nutrients for growth and development regular physical exercise- reduces risk of preganancy issus/complications BAD: smoking- doubles risk of abnormal bleeding drinking alchohol- increases risk of permature birth and baby having a low birthweight. MIGHT cause YOUR BABY TO have: A LONG TERM FETAL ALCHOHOL SPECTRUM DISORDER :>
38
what is pollination?
when pollen moves from the anther (male part where it is made) to the stigma (female part).
39
Parts of a flower include.... (draw and label a diagram)
MALE: Anther- produces the male sex cells (in the pollen grains) Filament- supports and holds anther Stamen- consists of the anther being held up by the filament FEMALE: Stigma- sticky to collect pollen grains Style- supports stigma and is the tube pollen grains travel down Ovary- produces the female sex cells (ovules) Carpel- consists of the stugma, style and ovary. Ovule- inside the ovary NON GENDER???? petal- may be brightly coloured to attract insects sepal- protects the unopened flower (technically the outer layer of the petals.) Nectaries (receptacle)- produces sugary solution (nectar) to attract insects.
40
Insect VS WInd pollinated flowers: fill this in petals nectar scent pollen anthers stigma
Insect: petals: brightly coloured to attract insects nectar: sweet-tasting nectar to attract insects scent: sweet-smelling to attract insects pollen: sticky/spiky so it sticks to insect anthers: inside the flower so they brush against insect when insect is collecting nature stigma: inside flower and sticky so it brushes against insect and pollen sticks to it when insect in collecting nectar. Wind: petals: dull coloured so flower doesn't waste resources becuase it doesn't make a difference to wind nectar: no nectar so they don't waste resources scent: unscented so they don't waste resources to make the scent. pollen: smooth and light so it can be carried long distances by wind anthers: outside flower so pollen can be easily brushed off by wind stigma: outside and feathery so pollen easily caught by wind.
