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 native plants need fire to germinate?
Some native plants that require fire to germinate include certain species of pine trees, such as the lodgepole pine (Pinus contorta) and the knobcone pine (Pinus attenuata). Additionally, some species of chaparral plants, like manzanita (Arctostaphylos spp.) and ceanothus (Ceanothus spp.), have seeds that benefit from fire for germination due to the heat breaking seed dormancy.
What are tiny cells from which some plants germinate?
Tiny cells from which some plants germinate are called spores. Spores are reproductive structures that are produced by certain plants, such as ferns and mosses, and are capable of developing into new plants under the right conditions.
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.
Why the seed cannot germinate without water?
Some species do and some species don't. All species need their seeds to be in their own type of environment to germinate.

How do fires help chaparral biomes?
Fires help the Chaparral by "refreshing" the vegetation that grows there. Some plants can only grow and germinate when a fire occurs. They are called "fire anuuals." An example is the herbaceous species.The Chaparral vegetation(ex. shrubs) have 4 different strategies to survive a fire:1. Obligate resprouters. These plants survive fires by resprouting only e.g. Toyon and Scrub Oak.2. Obligate seeders. The adult plants die in the fire. Seeds receive a fire cue and then germinate e.g. Ceanothus.3. Fire followers. These annual plants require some fire cue for germination..4. Facultative seeders: The adult plant resprounts and a fire cue enhances seed germination.
What are tiny cells from which some plants germinate?
Tiny cells from which some plants germinate are called spores. Spores are reproductive structures that are produced by certain plants, such as ferns and mosses, and are capable of developing into new plants under the right conditions.
Do I need light to germinate seeds?
Yes, most seeds require light to germinate, but some seeds can germinate in darkness.
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.
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.
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.
What is a sentence using the word germinate?
The seeds of some plants can survive in a dry condition for hundreds of years and then germinate when placed in an environment with plenty of water.
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.
Why the seed cannot germinate without water?
Some species do and some species don't. All species need their seeds to be in their own type of environment to germinate.
