Total questions: 22
Worksheet time: 6hrs 30mins
All living organisms need gases to live. In plants, gas exchange occurs mainly in the –
waxy covering over the leaf
stomata of the leaf
roots
lungs
What form of energy is stored in food?
light energy
kinetic energy
chemical energy
mechanical energy
Which of the following processes converts radiant energy from the sun into chemical energy that is stored inside a cell?
Excretion
Replication
Photosynthesis
Digestion
This equation represents a biological process that takes place in the –
cell membrane
mitochondrion
cytoplasm
chloroplasts
Which diagram provides evidence of how gravity affects root formation in a sprouting seed?
Seed A
Seed B
Seed C
Seed D
Gavitropism (geotropism) is a response of plants that causes the roots of seeds to grow –
towards the sky
sideways
towards the center of the Earth
inward
What is the main function of chloroplasts in a plant cell?
They produce proteins.
They store water and food.
They perform photosynthesis.
They protect cells from the surrounding environment.
Green plants produce their own food during photosynthesis. Which of these statements about photosynthesis is true?
Water is one product of photosynthesis.
Oxygen is one product of photosynthesis.
Chlorophyll is one product of photosynthesis.
Carbon dioxide is one product of photosynthesis.
Plant B is most likely showing a response to –
Gravity
Light from the window
Touch
Dry soil
Plant A and Plant B were identical when the investigation began and were given the same amount of water and fertilizer. The most likely explanation for the differences in plant growth is that light –
bends the stems of plants
is needed for plant growth and development
is not as important as water
is not as important as fertilizer
How do organisms get the energy they need?
Plants get energy from fertilizers, and animals get energy by drinking water.
Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.
Plants do not require energy because they do not move, and animals get energy by performing exercise.
Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.
What is the advantage for a plant to produce broad leaves compared to narrow needle-like leaves?
Broad leaves provide more surface area for water loss.
Broad leaves provide more surface area for gas exchange.
Broad leaves provide more surface area for light capture.
Both A and B are correct.
A severe thunderstorm moved through Dallas producing wind speeds in excess of 60 mph. It stripped all the leaves from the seedlings in its path. These seedlings eventually died. What probably caused the deaths of these young trees?
Heavy rainfall caused severe flooding which drowned the trees.
The wind damaged the trees’ roots, so they were not able to absorb water and nutrients from the soil.
The weakened trees were attacked by insects which caused them to die.
The trees died due to lack of energy.
Photosynthesis is the process in which cells use oxygen to break down food and release stored energy.
True
False
Carbon dioxide (CO2) is a waste product in the process of photosynthesis.
True
False
Turgor pressure is the outward force exerted by water on the cell wall of a plant cell.
True
False
Tropism is the turning of a plant in a particular direction due to an external stimulus.
True
False
According to the diagram, Product 2 is -
oxygen produced by photosynthesis
oxygen produced by respiration
carbon dioxide produced by photosynthesis
carbon dioxide produced by respiration
A student placed a flower in a vase but forgot to add water. The picture above shows the flower’s appearance after a few days. What force/s contributed to the flower’s appearance?
Gravity
Loss of turgor pressure
Geotropism
Loss of turgor pressure and gravity
Which question is this apparatus most likely designed to answer?
Does turgor pressure affect the absorption of water?
Does geotropism affect the growth of a plant?
Does phototropism affect the growth of a plant?
Do plants exhibit fight or flight reactions?
Which of these equations does the diagram support?
Oxygen + Water + Sunlight = Carbon dioxide + Glucose
Glucose + Water + Sunlight = Carbon dioxide + Oxygen
Water + Carbon dioxide + Sunlight = Glucose + Oxygen
Carbon dioxide + Glucose = Sunlight + Water + Oxygen
The glucose produced in the leaf can be described as –
potential chemical energy
kinetic nuclear energy
potential nuclear energy
kinetic chemical energy
