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.
Why do some plants need fire to germinate?
Some plants have adapted to rely on fire for germination because the heat and smoke from fires can trigger the germination process by breaking seed dormancy or stimulating the release of certain chemicals in the seed coat. This adaptation allows these plants to take advantage of the open space and nutrients created by a fire to establish themselves successfully.
How plants need warmth to germinate?
Germination needs active cell division for which a moderate temperature of about 24 degree celsius is needed.
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.
How is a wildfire good for the ecosystem?
they burn down bad plants that will cause the plants to die and they burn down the trees to create more nutrients in the soil.Also some plants need fires so that thier hard cover or seed can melt in order for them to grow.

Do marigolds need light to germinate?
Yes, marigold seeds need light to germinate.
How much water do you need to germinate a seed?
you need one cup of water to germinate a seed
Do plants need light to germinate, and if so, how does the presence or absence of light affect the germination process?
Yes, plants need light to germinate. Light is essential for triggering the process of germination in most plant species. The presence of light stimulates the production of chlorophyll, which is necessary for photosynthesis and growth. In the absence of light, some seeds may still germinate but the seedlings will be weak and pale, as they lack the energy source provided by photosynthesis.

Do I need light to germinate seeds?
Yes, most seeds require light to germinate, but some seeds can germinate in darkness.
Do seeds need light to grow, and if so, how does the presence or absence of light affect their growth process?
Seeds do not need light to germinate, but they do need light to grow and develop properly. Light is essential for photosynthesis, the process by which plants make their own food. Without light, plants cannot produce the energy they need to grow. In the absence of light, seeds may germinate but will not grow well and may become weak and leggy.
Do seeds need sunlight to start germinating?
Absolutely! Sunlight is essential for plants to grow.there is a big difference between what a plant needs to grow and what a seed needs to germinate. most seeds require darkness to germinate, some are light inhibited and a few require light to germinate- most notable of these is lettuce.
Does mint need light to germinate?
Yes, mint seeds do not require light to germinate. They can germinate in darkness or low light conditions.
