Tick five parts of a cell that are both plant and animal cell have.
Rigid Cell wall
What Three Thing do plants have that animals cell don't?
Where is the Genetic material Found in Bacterial Cells?
Where is the Genetic material Found in Animal Cells
Diffusion is the spreading out of particles from an area of high concentration to an area of a low concentration.
Tick three Substance that diffuse through cell membranes.
Tick two Substance that doesn't diffuse through cell membranes.
Tick three ways that palisade leaf cell is adapted for photosynthesis.
They are near the top layer so they're near to the light
Its a Thin Shape - Lot packed to the top of the leaf in a group
It packed with Chloroplasts
Tall shape, means that there's a lot of surface area - Exposed down the side for absorbing CO2
It a Short Shape - so many more can be packed in the leaf
Tick three ways that a sperm cell adapted for swimming to an egg cell
The mitochondria provide the energy the sperm needs
The ribosomes provide the energy the sperm needs
A tissues is a group of organs working together to perform a particular function.
An organ is a group of different tissues that work together to perform a certain function.
Tick three examples of tissues in the human stomach and what they do.
Muscular Tissue - which move the stomach wall to chumup the food
Glandular Tissue - which makes digestive juices to digest food
Stomach Tissue - which digest food
Epithelial Tissue - which cover the inside and outside of thestomach
Epithelial Tissue - Which makes and secretes chemicalslike enzymes and hormones
Tick one name of an organ system
One example of a plant tissue. Tick the one below.
The Photosynthesis Equation is : Carbon Dioxide + Glucose ---> Water + Oxygen
What the green substance in leaves that abosorbs sunlight?
You carry out an experiment where you change the light intensity experienced by a piece of Canadian pondweed by changing the distance between the pondweed and a lamp supplying it with light.What three important thing must you kept constant for this experiment to be a fair test?
Same distance between the bulb and the pondweed
Same amount of water
Same amount of time
Same intensity of light
Why it's important that a plant doesn't get too hot? Tick one below.
Photosynthesis reaction rate speeds up
Photosynthesis reaction rate slows down
Why is glucose turned into starch when the plant need to store it later?
Starch is insoluble, so it doesn't effect the water potential in the plant. Glucose does dissolve in water, which would effect the water potential.
Starch is dissolvable, so it doesn't effect the water potential in the plant. Glucose is insoluble, which would effect the water potential.
Four other ways that plants can use the glucose produced by photosynthesis. Tick four below
Glucose is turned into lipids (fats and oils) for storing in seeds
Glucose converted into cellulose for making strongcell walls
Glucose is turned into starch and store in the roots, stems and leaves
Use some of the glucose for respiration
Glucose is turn into proteins
What is an Habitat?
A habitat is a place where an organisms lives
A habitat is where an organism is found
Tick five environment factor that can affect the distribution of organisms
Availability of Oxygen
Availability of Water
Amount of light
Availability of Carbon dioxide
Availability of Glucose
How do you work of the Mean of organism living in an area?
Number of organisms divide Number of quadrat
Number of organisms add Number of quadrat
Number of organisms times Number of quadrat
Number of organisms square Number of quadrat
