===About Plant Survival===
: [[Plant|Plants]] need [[air]] to '''survive'''. If you put a plant in space it would die without air.: [[Plant|Plants]] need light to grow and '''survive'''. Plants make their own food but the need light to make it. If there is not light the plant will run out of food and starve to death.
: [[Water]] is essential for all life on earth, both plant and animal.
: [[Plant|Plants]] need nutrients for their '''survival'''. When the plant makes its own food it uses minerals from the soil to make proteins and fats it needs to grow.
: A [[plant]] needs room to grow. If it is placed in a small pot the plant will not grow very large. The bigger the pot the bigger the plant can grow.
===Specialised Plants===
: Not all [[Plant|plants]] need the same amount of water, sunlight or a warm temperature.
: A cactus is a plant that lives in the desert and is specially [[adapted]] to '''survive''' without much water.
: A fir can survive covered in snow in very cold winters without dying, but an orange tree would die if it got that cold.
