The seeds are shut inside the cone. The cone only opens in response to the higher heat levels and temperatures of fire. Once so opened, the cone releases the seeds. The seeds fall to the ground, to be eaten or to grow into trees.

What does the fire do to assist the trees to reproduce?
It forces the seeds (such as pinecones) to open so they will be allowed to germinate. The heat activates them to open because the seed thinks it is warm enough to let the seeds germinate. And let the plant reproduce.
Does dry seeds respire?
No, as cell respiration (anaerobic and aerobic), both need the seeds to be alive.
Why do plants need seeds?
plants use seeds to carry on their species so that they will not become extinct.
What are the disadvantages of seed dormancy?
Seed hibernation, also called seed dormancy, is the ability of a seed to remain in hibernation when there is a lack of things essential to their development (water, sunlight, nutrients, etc.) or in harsh conditions (extreme cold, extreme heat, hard ground, etc.).
Why do seeds become dormant?
Seeds are designed to dry out which puts the embryonic plant into dormancy. However some seeds also have a hard outer covering which protects the seed and prevents water entering the seed for many years. Such seeds (eg the poppy) can have a dormancy exceeding 10s of years. Some seeds also need frost before they will germinate a process called cold stratification. Others need fire to start the process.
Why does the fire pine need heat to release its seeds?
The seeds are shut inside the cone. The cone only opens in response to the higher heat levels and temperatures of fire. Once so opened, the cone releases the seeds. The seeds fall to the ground, to be eaten or to grow into trees
Why do seeds need wild fires to survive?
Some species are adapted to wild fires. The seeds can not germinate until they have been exposed to fire. The seeds are NOT damaged by the fire and after the fire they sprout taking advantage of the space the fire has left and the minerals in the fire's ashes.
What does the fire do to assist the trees to reproduce?

What do you need to start a fire?
You need oxygen, heat, and fuel.
Does cooking seeds make them grow faster?
Cooking seeds will make sure the seeds do not grow. The only seeds that need heat to germinate are some evergreen tree seeds.
What are the 3 ingredients of fire?
For fire you need three main ingredients. First you need a fuel, this fuel can be anything that burns like wood for example. Second you need oxygen, without oxygen a fire cannot burn. Finally you need heat, even though fires give off heat you still need it to start a fire. If you remove any one of these three ingredients then the fire will die.
Why do you need car engine to heat heat up quickly?
it can cause to fire and
What Australian plants require their seeds to be heated in order to germinate?
Banksia seeds require fire to germinate, while many species of acacia (wattle tree) also need heat in order to germinate. Flannel flower seeds also benefit from bushfires, while Boronia requires smoke to germinate.
What ingredients do you need for a fire?
Fuel, oxygen and heat.
Who discovered that fire helps reproduce trees?
Many researchers have arrived at that conclusion. The first are undoubtedly lost to history. Some pines are fire climax pines and need fire to release the seeds from the pine cones. Some biomes need fire to clear underbrush to allow seedlings to gain a foothold. See the link to read more about the role of fire in a Sequoia forest.
What do you need to create fire?
To create a fire you need a fuel source of some kind, oxygen (O2), and a heat source.
What does fire need to stay lit?
heat oxtgen and fuel
