Life cycles :red_flag::+1:
What is a life cycle?
All living things go through changes
The birth, growth, development and reproduction makes a life cycle
Adults are able to reproduce
the young go through what their parents went through in a life cycle, thus it repeat itselfs
Life Cycle is important as it ensures
the survival and continuity
of living things
How are life cycles similar or different
Different living things have different stages of development(some have more than others)
a young may look
similar or different
from their parents
Life cycles of animals
Human
Egg
(Inside female body) to
young
to
adult
The egg must be fertilised in order to have a baby
young looks like adult. Size and some of the features changes
A human adult can also reproduce
Chicken
Egg (laid on land) to young to adult
A hen reproduces when it becomes an adult
The hard shell of the egg protects the young animals inside
A chick hatched from the egg
The chicks looks alike to their parents
An adult chicken is able to reproduce
Frog
3 Stages:Egg to tadpole to adult
An adult doesn't have a tail and gills
adults use its lungs on land and skin when underwater
An adult frog is able to reproduce
A female frog lay many eggs to ensure young can reach adulthood
Eggs laid in water are surrounded by a jelly-like covering
Tadpoles have tails and do not look their parents
tadpoles breath through gills when swim; they are fed on tiny plants
When tadpoles grow, they begin to develop legs
Cockroach
3 Stages: Egg to nymph to adult
young looks quite similar but
smaller and dont have wings
young goes through moulting (sheds old skin and grows a new one ) several times
A female cockroach lays egg cases with 15-60 eggs in a dark and soft place
An adult has wings and can fly is able to reproduce
Grasshopper
Similar to cockroach
The female grasshopper lay eggs in the soil
Butterfly
4 stages: Egg to larva (caterpillar) to pupa to adult
The pupa spins a case around its body and
the pupa
develops in it
pupa does not need food, young does not look like adult
A female lays eggs on a suitable plant where young can find food after hatching
The eggs hatch into larvae which feed on leaves and moults several times
Mosquito
4 stages: Egg to larva (larva to pupa) to pupa to adult and adult to egg(new gen.)
The wriggler hangs on the water surface, feed on tiny organisms and small food particles and moults a few times when it grows
An adult mosquito lay eggs in still water
After its final moult, larva develops into a pupa; it stays near water surface and does not feed. The pupa develops into an adult in the adult
Butterfly will spread and dry its wings before flying off. It can reproduce
beetle
like butterfly
Life cycle of most plants
Most plants grow from seeds(or spores)
Seed
roots grow out first before shoot
Young Plant
Adult Plants
more leaves develop to make food
roots grow to absorb water and minerals from the soil
The flowers develop into fruits and seeds
The seeds grow into new plants
leaves develop and the young plant start making its own food
