Why do some plant seeds need fire in order to germinate?
Some plant seeds require fire to germinate as it creates the right conditions for their growth. Fire can break down tough seed coats, making it easier for water to penetrate and initiate germination. Additionally, the heat can trigger chemical changes in the seeds, and the ash left behind enriches the soil with nutrients. This adaptation is particularly beneficial in fire-prone ecosystems, where such events can create opportunities for new plant growth.
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.
Do all seeds germinate immediately after they dispersed?
No, in fact some seeds lay dormant for many years and others are triggered by heat (only germinate after a forest fire).
Do all seeds germinate immediately after they are dispersed?
No, in fact some seeds lay dormant for many years and others are triggered by heat (only germinate after a forest fire).
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.

Seeds dispersed by fire and their plants name?
Some seeds dispersed by fire include pine cones, which release their seeds after being exposed to intense heat. Plants that have adapted to depend on fire for their seeds to germinate include certain species of chaparral shrubs like manzanita and ceanothus.

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.
Why is fireweed one of the first plants to germinate after a volcano or fire?
Fireweed is one of the first plants to germinate after a volcano or fire because its seeds are stimulated by the heat and chemicals released during the eruption or fire. The plant's light, wind-dispersed seeds can quickly colonize newly disturbed areas with minimal competition from other plants. Additionally, fireweed is well-adapted to thrive in nutrient-poor soils, making it particularly suited to these harsh, post-disaster environments.
Why is fire used?
Well you use fire to keep warm, cook something, melt something that is frozen, heat something up, and if controlled it can germinate seeds in a forest, fire has many uses.
What is the adaptation of a wattle?
One of the adaptations of the Australian wattle is its seeds. They are very hardy and can survive in the ground for decades. The seeds also germinate in their thousands. Another 2 include the phyllodes and its fire resistance.
Which plant has seeds that might be stimulated to grow after a fire?
Pine tree
You've obtained the seeds from a plant you would like to grow in your yard You plant a few of them but they do not germinate What type of treatments might promote the germination of these seeds?
It depends on the seeds. Some seeds, like alfalfa seeds and clover seeds, need to be coated with a specific rhizomidous bacteria that helps break down their hard outer coating. Other seeds require scarification or fire or even being soaked in water to soften or break apart that hard outer shell of the seed. Many other seeds do not require any of the above, and simply need a specific depth of soil to be planted in, a little bit of water, sunlight, and time.
