Independent Variable - Answer The experimental factor that is manipulated; the variable whose effect is being studied. Placed on the x-axis (horizontal) on a graph. Dependent Variable - Answer The variable that is measured in an experiment. Placed on the y-axis (vertical) on a graph. Scientific theory - Answer Must be repeatable. Possible to be disproved and capable of change. Sampling and Sample Size - Answer Random sampling is the preferred, but isn't always possible. A large sample ...

AQA A Level Biology: Gas Exchange in Plants Graded A+ How are leaves well adapted for gas exchange? - air spaces allow carbon dioxide to diffuse - irregular spongy mesophyll layer increases the SA:V ratio - stomata allow gases to diffuse in and out How does the waxy cuticle help to reduce water loss? - Thick waxy cuticle means there is an impermeable layer which reduces evaporation from the surface. Its thickness also increases the distance for diffusion Compensation point Xerophy...

The four major organs of plants -->Roots, Stems, Leaves, and Flowers Roots -->Anchor a plant to its substrate, store food, absorb water and minerals, and transport materials to other areas of the plant Two parts of a root are: -->Root hairs and mycorrhizae root hairs -->greatly increase the absorbing surface area mycorrhizae -->are fungi with filaments that absorb water and nutrients for the plant while the plant roots supply them with sugar Stems -->support the above gr...
