Process in which particles move from a region of a liquid or gas where they are high concentration, to a region where they are low in concentration

PHOTOSYNTHESIS

Process in which plants use light energy, carbon dioxide and water to make glucose

Guard Cells

CELL SURROUNDING THE STOMATA THAT OPEN AND CLOE TO CONTROL THE EXCHANGE OF GASES AND WATER LOSS

Palisade Cells

PLANT TISSUE CONTAINING CLOSELY PACKED CELLS IN THE UPPER LAYER OF A LEAF

spongy mesophyll

the plant tissue in a leaf which has loosely packed cells and air spaces between them to allow gas exchange

fertilisation

Process where a male sex cell joins with a female sex cell

density

Measure of the concentration of mass in an object or material

Chemical Equation
