minerals.
3) Most of the seeds won't germinate.
4) If seed dispersal is not there, we can't see different plants in different areas.
5) If seed dispersal is not there, we can see only few plants in our surroundings.

T.Q.-Q.No. 2
A. 1) The seeds of caltropis are dispersed by wind.
2) The seeds of caltropis are light and have hairy structure at one end.

4) Seed that are dispersal through air are usually light and are either very small or are light
with wings on them or some hairy structures on them.
3. Name some plants where the dispersal of seed is by bursting of fruits.

Hey mate !!
Here is ur Answer ⤵️
- What happens if seeds are not dispersed ?
If the seeds did not spread out, they would fall in the parent bed itself leading into struggle for water, minerals and sunlight. As a result, none of the plants would grow properly or survive.
- Seeds dispersal is essential for survival of plants. ?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
- If seeds are not dispersed, there will be competition with the mother plant for air, water and minerals. ?
If seeds are not dispersed all seeds will fall under the parent plant and fight for water, minerals, sunlight. So they will not develop into healthy plants and many of them may even die. So seed dispersal is very important for a plant to grow.
- Most of the seeds won't germinate. ?
If the soil in your seed trays, containers or planting areas is too dry, you should be able to see or feel this fairly easily. Water well, taking care not to wash your seeds away or push them too deep into the growing medium, and your seeds may well still germinate in time.
- The seeds of caltropis are dispersed by wind. ?
In Calotropis, the seeds can be spread long distances by wind and water and can also be dispersed in mud that becomes attached to animals and vehicles.
- The seeds of caltropis are light and have hairy structure at one end. ?
They are the seeds of caltropis. These seeds have light and hairy structure at one end. They travel with wind and settle at a suitable place to germinate. Seeds that are dispersed through air are usually light and are either very small or are light with wings on them or some hairy structures on them.
- Name some plants where the dispersal of seed is by bursting of fruits. ?
Seed Dispersal by Explosions
Seed Dispersal by ExplosionsIn this case, as the fruits get ripened, it shoots out its seeds into the external environment. This type of seed dispersal is mainly seen in those plants having pods. Okra, Lupins, gorse, and broom are a few examples of plants whose seeds are dispersed by Explosions.
- Describe the dispersal of seeds through human being ?
Humans may disperse seeds by many various means and some surprisingly high distances have been repeatedly measured. Examples are: dispersal on human clothes (up to 250 m), on shoes (up to 5 km), or by cars (regularly ~ 250 m, singles cases > 100 km). ... Deliberate seed dispersal also occurs as seed bombing.
The questions which I did not get :
* Most of the seeds won't germinate. ?
* If seed dispersal is not there, we can't see different plants in different areas. ?
* If seed dispersal is not there, we can see only few plants in our surroundings. ?
* They travel with wind and settle at a suitable place to germinate. ?
* Seed that are dispersal through air are usually light and are either very small or are light

Hope it helps you ✔️
Thank you ❣️

Answer:
➖(a)If seeds are not dispersed they will only grow in the same area and gradually strangle each other. They need to disperse to find new soil.
