Plants need a source of energy in order to perform photosynthesis. From which source do plants receive the energy needed to perform photosynthesis?
oxygen
sugar
water
sunlight
Which of the following is the reason that nitrogen is important for plants?
it can kill bacteria
to build proteins
to help us breath
for photosynthesis
Which of the following describes the growth of a plant in response to touch or contact?
geotropsim
thigmotropism
thermotropism
phototropism
Nitrogen is the most common gas in Earth's atmosphere, and is necessary for the survival of all ecosystems. How do plants get the nitrogen they need?
free nitrogen in the atmosphere
animal waste
bacteria release it into the air and the plants absorb it through their leaves
bacteria turn it into nitrates, nitrites, or ammonia and the plants absorb it through their roots

to protect the flower until it is ready to reproduce
to help with pollination
to attract pollinators
to make food during photosynthesis
How does the stigma help with pollination?
it sucks the pollen into the style
it attracts pollinators
it protects the flower until it is ready to reproduce
it is sticky trap pollen
Which of the following is NOT a way that plants protect themselves?
biting
thick cell wall
thorns
oils that harm animals
Which of the following processes occurs ONLY during the day?
photosynthesis
cellular respiration
photosynthesis and cellular respiration
growth and cellular respiration
Which of the following describes the growth of a plant in response to light?
thigmotropism
chemotropism
thermotropism
phototropism
Where does reproduction take place in flowering plants?
leaves
pistil
flower
stamen
Which of the following is NOT a way that plants are pollinated?
wind
water
insects
self-pollination
Which of the following is NOT a feature plants use for survival?
stems
roots
petals
leaves
What does a plant need in order to go through photosynthesis?
oxygen, carbon dioxide, and water
carbon dioxide, water, sunlight, and chlorophyll
water, sugar, sunlight, and carbon dioxide
oxygen, sugar, and sunlight
Which of the following describes the growth of a plant in response to water?

hydrotropism
What part of the flower contains eggs?
stigma
style
anther
ovary
What part of the flower produces pollen?
filament
anther
stigma
sepal
Plant growth in response to a stimulus is called?
cellular respiration
transpiration
fertilization
tropism
The process in plants whereby a plant makes its own food is called?
fertilization
photosynthesis
cellular respiration
transpiration
Where does reproduction take place in gymnosperms?
roots
needles
cone
bark
How do stems help a plant to survive?
helps with photosynthesis
attract pollinators
conducts water & nutrients to the leaves
collects sunlight
How are thick cell walls important for plant defense?
release oils that can be harmful to animals
certain animals are irritated by them
they will hurt an animal if it steps on them
keep the plant from being penetrated by animals
How is cellular respiration important for the survival of plants?
produces sugar
produces energy
produces oxygen
produces pollen
When pollen travels down the style of a flower and combines with the egg inside the ovary it is called...
pollination
photosynthesis
respiration
fertilization
How can the scent of a plant be a defense mechanism?
it releases oils that can be harmful to animals
they will hurt an animal if it steps on them
certain animals are irritated by them
keep the plant from being penetrated by animals
What does cellular respiration produce from glucose and oxygen?
carbon dioxide, water, and energy
carbon dioxide and oxygen
water, oxygen, and sugar
oxygen and glucose
How do plant roots help a plant to survive?
they absorb water and nutrients
attracts pollinators
helps with photosynthesis
keeps the plant from being penetrated
How do leaves help a plant to survive?
make food through photosynthesis
absorbs water and nutrients
keeps the plant from being penetrated
conducts water and nutrients from the leaves
