The diagrams show the life cycles of two plants. How are the life cycles of these two plants similar? In their life cycles, both plants –
develop the same kind of flowers
have exactly four stages in their life cycles
have the same number of leaves as adults
begin life as seeds and grow larger
These diagrams show the life cycles of a cockroach and a tenebrio. Which statement correctly compares these two life cycles?
both animals go through four stages of development
neither the young nymph nor the larva have wings
neither organism's body changes as it develops
when both emerge from eggs, they look like adults
The main function of the larva stage in animals like the butterfly is to -
protect the eggs from predators
change and develop new body parts
store energy by constantly eating
reproduce and have offspring
The life cycle of the tomato plant is illustrated here. Which stage in the diagram is the adult plant?
A
B
C
D
All life cycles, whether they are plant or animal life cycles include -
growth and change
spreading of seeds
larva and pupa stages
giving milk to young
Plants have flowers so they can reproduce. Therefore, when a plant has flowers, we know that the plant -
does not need insects to feed on it
live in a warm, moist climate
has readed the adult stage
is not able to produce seeds
How is the life cycle of a butterfly similar to the life cycle of a frog? Both life cycles –
include a tadpole stage
produce adults with wings
take place in the water
begin with eggs
One way in which a plant life cycle is like an animal life cycle is that both plants and animals –
use seeds to reproduce
live for hundreds of years
lay eggs that hatch
grow larger over time
The life cycle of a darkling beetle is shown here. Which stage represents the change from larva to adult?
A
B
C
D
Adult plants reproduce by forming seeds. These seeds grow to become new plants. Which stage in a beetle’s life cycle is most similar to a plant seed?
Egg
Larva
Pupa
Adult
In a complete metamorphosis, the animal hatches from an egg as a nymph.
true
false
Inside the pupa, an insect becomes
larva
egg
