Question
What are the female parts of a plant?
(Be able to label them on a diagram)
Answer
Pistil, Stigma, Style, Ovary, Ovule
Page in the ISN
What are the male parts of a plant?
(Be able to label them on a diagram)
Stamen, Anther, Filament, Pollen
How do plants reproduce?
Pollen is transferred from the anther to the stigma by a pollinator. The pollen travels down the style and
fertilizes the ovules. The ovary becomes a fruit, and the ovules become seeds.
How does a flower protect itself?
The sepals and the petals surround the reproductive organs so that the flower is able to reproduce.
What is photosynthesis? Why does it
occur?
Process by which plants make food. Sunlight combines with chlorophyll and abiotic factors (carbon dioxide and
water) to form glucose and oxygen. Plants must go through photosynthesis because they are unable to consume
their food.
What is respiration?
Process organisms use to release the energy stored in the glucose.
What is transpiration?
Evaporation of water from leaves that helps to balance the plant’s water content
Write the equation for
photosynthesis. Label the reactants
and products.
Reactants
Carbon dioxide + Water + Sunlight
Write the equation for respiration.
Label the reactants and products.
Reactants
Oxygen + Glucose
What is the difference between
photosynthesis and respiration?
Photosynthesis makes (food) energy and respiration releases energy. These two processes are opposites of each
other.
What is the role of the stomata?
What is the role of the chloroplasts?
Stomata are tiny holes that exchange gases and allow water to evaporate.
Chloroplasts contain chlorophyll that is needed for photosynthesis.
What are biotic factors?
Biotic factors are the living things in an ecosystem. (Plants, animals, organisms)
What are abiotic factors?
Abiotic factors are the nonliving things in an ecosystem. (Air, water, soil)
How do abiotic factors affect biotic
factors in an ecosystem?
Abiotic factors combined with biotic factors allow for processes such as photosynthesis and respiration and start
the food chain
What are the basic needs for all living
things?
Air, water, food, shelter
Products
Glucose + Oxygen
Products
Carbon Dioxide + Water + ATP (Energy)

Food Webs
Plant Adaptations

How do these factors work together in
an ecosystem?
Ecosystems are codependent systems. Everything within an ecosystem needs other factors in order to thrive and
survive. For example, consumers need producers, producers need sunlight, etc.
How does energy flow within an
ecosystem?
Energy is created in the plants (producers). Consumers take in the producers and the energy is then transferred
to the consumer. Food chains and energy pyramids show how energy is transferred.
What is a food chain?
See vocabulary
What is a food web?
See vocabulary
Why does energy decrease as you
move toward the top of the energy
pyramid?
Less energy is available as more energy is needed by the higher organisms.
What is a producer? Give two
examples.
Definition: See vocabulary
Examples: grass, trees
What is a consumer? Give two
examples.
Definition: See vocabulary
Examples: humans, lions, cows
What is a decomposer? Give two
examples.
Definition: See vocabulary
Examples: mushrooms, fungi
What are plant adaptations? Give
three examples.
Definition: Plant adaptations are changes that a plant makes
in order to survive in its environment
Examples: Answers will vary
(tropisms, longer roots)
What is phototropism? Draw a picture
that shows phototropism.
Definition: A plant’s response to light. Can be either positive
(toward the light) or negative (away from the light)
Picture:
What is gravitropism? Draw a picture
that shows gravitropism.
Definition: A plant’s response to gravity. Can be either
positive or negative
Picture:
What is thigmotropism? Draw a
picture that shows thigmotropism.
Definition: A plant’s response to touch. Can be either positive
or negative.
Picture:
How can tropisms help a plant
survive?
The response to stimuli can save the plant or help pollinate, climbing helps get to light, which plants need for
photosynthesis.
