PLANT AND ANIMAL LIFE CYCLES
4th grade Chapter 3 Science
10 POINTS
How
does a new plant
begin to grow?

It germinates
TEN POINTS
What
a
is an embryo?
plant or animal in the earliest stages
of development
TEN POINTS
What

is an egg?
the first stage in the life cycle of most animals
20 POINTS
What
is the larva stage in an
animal’s life cycle?

a worm-like form and the second stage of complete
metamorphosis
20 POINTS
What
is the nymph stage in
the life cycle of some
insects?

the second stage of incomplete metamorphosis
20 POINTS
What
are 3 traits that are
inherited to the offspring from
the parent?
Hair color
 Eye color
 Shape of leaves or color of flower

30 POINTS
What
are the 3 stages in the life
cycle of a plant?
Pollen moves from stamen to pistil where the seeds are
produced
b. The seeds are released
c. Seeds germinate into new plants
a.
30 POINTS
Do all plants have the same
life span?

No, some plants live for only one growing season such
as a tomato plant, others grow for 100’s of years such
as redwood trees
30 POINTS
 Describe
one way the life cycles of
insects and mammals are different?

Insects are hatched from eggs while mammals are
born live.
40 POINTS
What are some things that could
affect the life span of an
organism?

Supply of air, water, nutrients, disease could all
affect the life cycle of an organism.
40 POINTS
Describe
the 3 stages of
INCOMPLETE Metamorphosis.

Egg, nymph, adult
FINAL JEOPARDY – 50 POINTS
Describe
the 4 stages of
COMPLETE Metamorphosis

Egg, larva, pupa, adult
15 COMPARE: HOW IS THE LIFE CYCLE OF A BIRD
DIFFERENT FROM THE LIFE CYCLE OF A BEAR? HOW
ARE THEIR LIFE CYCLES SIMILAR?
Different:
Birds lay eggs and bears
do not.
Alike:
Both are born as infants who
grow up to look like their parents.
16. INFER: IF THE NUMBER OF BEES IN AN AREA
DECREASES, HOW MIGHT THE FLOWERING PLANTS IN
THE AREA BE AFFECTED? EXPLAIN.
Plants
rely on bees to move
pollen from stamen to pistil to
create seeds.
17. APPLY WHAT MIGHT HAPPEN IF YOU TOOK THE
POLLEN FROM A ROSE BUSH THAT YELLOW FLOWERS
AND PUT IT ON THE PISTILS OF A ROSE BUSH THAT
HAS PINK FLOWERS. EXPLAIN YOUR THINKING.
Rose
plants might produce
some offspring w/pink flowers
or some yellow and pink or
orange, or no seeds at all.
18. SYNTHESIZE WHAT ARE SOME OF THE SIMILARITIES
BETWEEN PLANT LIFE CYCLES AND ANIMAL LIFE CYCLES?
Both
plants and animals are
born, grow to become adults and
die
19. EVALUATE YOUR FRIEND SAYS THAT THE LIFE
SPAN OF A PLANT OR AN ANIMAL ALWAYS DEPENDS
ON THE SIZE OF THE ORGANISM. HOW WOULD YOU
RESPOND TO THIS STATEMENT?
It
is true that most large organisms
live longer than smaller organisms.
20 ANALYZE WHEN DRAGONFLIES ARE BORN, THEY DO
NOT HAVE WINGS. BUT ADULT DRAGONFLIES DO HAVE
WINGS. HOW CAN A NEWLY BORN DRAGONFLY LOOK SO
DIFFERENT FROM AN ADULT DRAGONFLY. EXPLAIN.
dragonflies
go through
metamorphosis. Animals grow up to
look like their parents.
