Plant structure
What part of the plant anchors it to the ground and absorbs water?
Roots
What two raw materials do plants need for photosynthesis?
Carbon dioxide and water
Name one adaptation desert plants have to survive with little water.
Ribs/ spikes/ flowering quickly/ shallow roots ect.
What is an organism?
A living thing
What is a variable
Anything that can change and can be measured
What is the main function of leaves in a plant
To photosynthesize (make food for the plant)
What is the main product of photosynthesis?
Sugar
How do tundra plants survive cold temperatures?
By growing close to the ground in groups, and having shallow roots.
What kingdom do plants belong to?
Kingdom plantae/ plant kingdom
Dependent variable - plant growth
Describe the role of the stem in a plant.
It provides support and contains vascular tissue
Describe the process of photosynthesis in simple terms.
Energy from the sun combines with carbon dioxide and water to make sugar and oxygen. The plant uses the sugar as food for energy.
How do shady area plants compete for light?
By growing large leaves, and growing upwards where they can access more light.
List the taxonomic ranks
Domain, kingdom, phylum, class, order, family, genus, species
Explain the difference between a dependent and independent variable.
The independent variable is the variable that we are changing. The dependent variable is what we are measuring.
What is the name of the organelle that allows leaves to photosynthesize?
Chloroplast
What role does sunlight play in photosynthesis?
The energy from the sunlight is used to combine carbon dioxide and water together
Describe a feature of a plants adapted to aquatic conditions.
Having flexible leaves/growing close to the surface/ having holdfasts/ air bladders.
Name one characteristic that all plants share
They're all living things, they all photosynthesise, they all have a waxy cuticle on the outside.
Why should only one variable at a time be changed in a scientific investigation?
So that it is a fair test.
What is the name of the green pigment in plants that captures energy energy from the sun?
Cholorphyll
Explain the importance of photosynthesis for ALL living organisms.
Photosynthesis is extremely important for plants, as it allows plants to make food. Photosynthesis is important for animals because the oxygen that animals need to survive is produced through photosynthesis.
Their bright colors and smells attract insects which will land on the flower. This helps with pollination.
List the different words that MRS GREN stands for
Movement, respiration, sensitivity, growth, reproduction, excretion, nutrition
Why do we include a controlled variable in an experiment?
To make sure that your dependent variable is being affected only by the independent variable.
