Germination of seeds only occurs when the conditions are right.
What are these conditions?
air, water and soil
air, water and light
water, oxygen and warmth
warmth, water and carbon dioxide
Sheila wants to investigate whether water is needed for germination. She set-ups an experiment as shown above. She used 5 seeds for each tube and placed both at the room temperature. After 5 days, she noticed that only seeds in tube A germinate.
Based on that, indicate the constant variables in her experiment.
the presence of water
the number of seeds
the temperature
the number of seeds and the temperature
From the experiment above, it is found that seeds in B did not germinate.
Explain, why this is so?
seeds B do not have oxygen
seeds B do not have water
seeds B do not have suitable heat
seeds B do not have oxygen, water and it is cold
From the experiment above, it is found that only seeds in A germinated.
Explain, why this is so?
seeds A have water and warmth.
seeds A have water, warmth and carbon dioxide.
seeds A have moist cotton and warm temperature.
seeds A have water, warmth and oxygen.
The purpose of seed dispersal is for the seeds to __________.
germinate at the same time
move to the same place and grow
move further away from the parent plant
compete with one another for minerals in the soil
How are dandelion seeds dispersed?
by animals
by explosion or bursting
by wind
How are coconuts dispersed?
by animals
by water
by wind
Why it is better for seeds to be scattered far and wide?
To provide shelter to other animals.
For farmers to see which soil is good for the plants.

What does it mean when a plant adapts?
It grows on the rainforest floor or under water.
It changes itself to fit in better with its environment.
It grows giant leaves and has very bright flowers.
It converts its surroundings into a kinder climate.
Why do plants adapt to their environments?
in order to give the surrounding animals and people enough food to survive
in order to get the water and sunlight they need to survive in a harsh environment
in order to block sunlight from the floors of the ocean and the rainforest
in order to grow very tall and to become as bright and colorful as they can
How do plants like water lilies float on the water?
They have seeds that float.
They have slippery leaves.
They have an air space in the stems.
They have poisonous leaves.
Florida wildfires that burn down acres of trees can occur at any time of the year. This change to the environment would be most harmful to animals that depend on which behavior for survival?
Sheltering below the ground in the dirt
Flying to warmer temperatures in the winter
Pollinating wildflower as a food source
Hiding from predators high in the trees
How are primary consumers different from secondary consumers?
Primary consumers eat only plants; secondary consumers eat other consumers.
Primary consumers eat other consumers; secondary consumers eat only plants.
Primary consumers eat plants and other consumers; secondary consumers eat plants and decompose matter.
Primary consumers eat plants and decompose matter; secondary consumers eat plants and other consumers.
A system of many food chains that interact with each other:
predator
consumer
