What happens to kangaroos during prolonged drought conditions?
They stop breeding until rain triggers
hormonal
response.
View source
What are eutherians also known as?
Placental mammals
.
View source
Where does embryonic development occur in eutherians?
Inside the
uterus
of the mother.
View source
What develops after fertilised eggs implant into the uterine wall?
A
placenta
connecting the young to nutrients.
View source
What is the outcome of the placenta's function?
It supplies
nutrients
and oxygen to the
embryo
.
View source
What type of development do eutherians exhibit?
Viviparous
development.
View source
How many young do placental mammals typically produce at a time?
One
to a
few
young.
View source
What is the relationship between parental care and survival of young in eutherians?
Increased
parental
care
improves
survival
chances.
View source
What are the differences between internal and external fertilisation?
Internal fertilisation
occurs inside the female's body.
External fertilisation occurs in open water environments.
Internal fertilisation has a higher chance of fertilisation.
External fertilisation produces many
gametes
but has a lower success rate.
View source
What is the main characteristic of external fertilisation?
Occurs
in open water
environments
.
View source
Why do organisms with external fertilisation produce large numbers of gametes?
To ensure
successful
fertilisation.
View source
What is a key advantage of internal fertilisation?
Higher chance of
successful fertilisation
.
View source
In which environments does external fertilisation typically occur?
Aquatic
or moist terrestrial environments.
View source
Which types of animals typically exhibit external fertilisation?
Most
invertebrates
and some vertebrates.
View source
Which types of animals typically exhibit internal fertilisation?
Some
invertebrates
and most vertebrates.
View source
What are the mechanisms that increase survival chances in species?
Nourishment for
developing
young.
Parental
care of eggs and/or young.
View source
What is the main process of sexual reproduction in plants?
Fusion of male and female
gametes
.
View source
Why is fertilisation more difficult for plants?
Plants cannot move to
facilitate
gamete
fusion.
View source
What do plants rely on for gamete transfer?
External agents like
pollinators
.
View source
What is the role of pollinating agents in plants?
To carry
gametes
from one parent to another.
View source
What happens to advantageous features in flowers over time?
They are selected by
natural
means.
View source
What are the parts of a flower involved in reproduction?
Carpel
(female parts)
Stamen
(male parts)
Petals (
non-sexual
parts)
Sepals (protect
unopened
bud)
View source
What is pollination in plants?
Transfer of
pollen
to the
stigma
.
View source
What occurs after pollen is deposited on the stigma?
A
pollen tube
germinates
and grows down the style.
View source
Where does fertilisation occur in flowering plants?
Inside the
ovary
.
View source
What is the outcome of fertilisation in flowering plants?
The
ovule
develops into a
seed
.
View source
What happens to the ovary after fertilisation?
It grows to become a
fruit
.
View source
What are the differences between self-pollination and cross-pollination?
Self-pollination requires less energy.
Cross-pollination
ensures greater variation.
Self-pollination occurs within the same plant.
Cross-pollination involves different plants.
View source
What is the advantage of self-pollination for plants?
Requires less
energy
and resources.
View source
What is a disadvantage of cross-pollination?
It requires energy to attract
pollinators
.
View source
How do wind-pollinated flowers typically appear?
Small, greenish, and
odourless
.
View source
Why do wind-pollinated flowers produce large amounts of pollen?
To compensate for inefficient
pollination
.
View source
What adaptations do animal-pollinated flowers have?
Bright colours and sweet
nectar
.
View source
How do pollinators help flowering plants?
They transfer
pollen
between flowers.
View source
What is the relationship between flower adaptations and pollinators?
Flowers
adapt
to attract
specific
pollinators.
View source
Why does a one-to-one relationship between a plant and an animal species reduce wastage of pollen?
It ensures pollen is deposited on the correct flower.
View source
What do animals such as insects, birds, and mammals seek in flowers?
A reward like
nectar
or pollen.
View source
What is nectar?
A
sugary
liquid
secreted
by
flowers.
View source
How do pollinators transfer pollen from one flower to another?
Pollen
rubs
onto their
bodies
during their
search.
View source
What features of flowers attract pollinators?
Scent
Colour
Markings
Shape
Nectar
