Correct Answer
Incorrect Answer 3
Incorrect Answer 2
What are male reproductive cells in flowering plants called?
Sepals
Pollen grains
Petals
Ovules
Where are ovules found in a flower?
Anther
Filament
Ovary
Style
What is the name of the process that moves pollen from the anther to the stigma?
Germination
Pollination
Respiration
Fertilization
In self-pollination, pollen moves:
From the anther to the stigma of the same flower or plant
From one plant to another of a different species
From an animal to the flower
Only through wind
Which type of pollination involves two different plants of the same species?
Cross-pollination
Wind pollination
Germination
Self-pollination
What is one common trait of a wind-pollinated plant?
Feathery stigma
Sticky stigma
Large pollen grains
Bright-colored petals
In which part of the flower are male gametes produced?
Sepal
Anther
Style
Ovule
What structure develops into a seed after fertilization?
Petal
Filament
Ovule
Anther
What structure develops into a fruit after fertilization?
Ovule
Sepal
Style
Ovary
Why is wind pollination often successful?
Pollinators are always nearby
Exposed anthers and feathery stigmas help catch wind-blown pollen
Flowers have sweet smells
Pollen grains are large and heavy
What happens to the zygote after fertilization in plants?
It dies
It develops into a group of cells
It forms pollen
It turns into fruit
What is the group of cells called that forms from the zygote?
Embryo
Ovule
Gamete
Seed
In electrostatics, what happens when a negatively charged balloon approaches a neutral object?
Positive charges in the object are attracted toward the balloon
The object becomes completely neutral
No change occurs
Electrons in the object move away from the balloon
Why are metals good conductors?
They have no electrons
Their electrons move freely
They resist charge transfer
Their electrons are tightly bound
What happens when a conductor is grounded?
It balances charge by exchanging electrons with the Earth
It explodes
Electrons stop moving
It becomes permanently charged
