Plant Organs
This organ is responsible for absorbing water and minerals.
Roots
Plants need this gas from the air to perform photosynthesis.
Carbon Dioxide
Male reproductive cells in plants are contained in this structure and are commonly called ______.
Pollen
The colourful part of a flower that attracts pollinators.
Petals
A statement that can be tested in an experiment is called a ___.
Hypothesis
The organ that transports water through xylem and sugars through phloem.
Stem
What is the word equation for photosynthesis?
Carbon dioxide + water → glucose + oxygen (in the presence of light and chlorophyll)
Name the part of the flower that produces ovules.
Ovary
Seeds form after this process occurs.
Fertilisation
Identify the independent variable in a test of how light affects plant growth.
Light intensity/ amount of light
What organ anchors the plant and sometimes stores food?
Roots
What pigment in chloroplasts captures light energy?
Chlorophyll
Define fertilisation
The joining of a male gamete (pollen nucleus) with a female gamete (ovule nucleus) to form a zygote.
Name two ways seeds can be dispersed.
Wind, water, animals... (any two).
Define the term “control variable.”
A factor kept the same to ensure a fair test.
Explain how stems are adapted to transport both water and sugars effectively.
Xylem carries water/minerals upward in hollow tubes; phloem transports sugars in both directions to supply all parts of the plant.
Explain why photosynthesis is essential for both plants and animals.
It produces oxygen for respiration and glucose as the base of the food chain (producers that get eaten by consumers)
Give one example of asexual reproduction in plants (including the type of plant).
Runners in strawberries, bulbs in onions, cuttings, or tubers in potatoes.
What is the function of the zygote in plant reproduction?
It develops into an embryo inside the seed, creating a new organism.
Why is replication important in experiments?
It increases reliability and helps reduce the impact of random errors.
The part of the leaf where most photosynthesis occurs.
Palisade layer (or mesophyll)
Describe how light intensity affects the rate of photosynthesis.
As light intensity increases, photosynthesis increases up to a point, after which other factors (CO₂, temperature) limit the rate.
What is an advantage of sexual reproduction.
Sexual → increases variation (but slower than asexual).
Explain how fruit helps ensure the survival of seeds.
Fruit protects seeds and aids dispersal (e.g., animals eat fruit and spread seeds).
When reading a graph, what axis goes along the bottom of the graph?
x-axis
