How does the bright color of some fruit help spread their seed?
For over a century, scientists have speculated that plants adapted brightly colored fruit to attract animals to eat them and spread out their seeds. Since birds tend to rely more heavily on their color vision, the reds would be easier to detect against the green foliage.
What helps to spread the seeds?
Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.
Why is the fruit important to the seed?
Fruits play an important role in the seed dispersal of many plant species. In dehiscent fruits, such as poppy capsules, the seeds are usually dispersed directly from the fruits, which may remain on the plant. In fleshy or indehiscent fruits, the seeds and fruit are commonly moved away from the parent plant together.
Why are fruits attractive and Colourful?
Past theories have suggested that fruits as a whole developed in such a rainbow-esque way in order to attract the attention of animals, who spread their seeds by way of eating them. A bright red pop of a berry cluster is easier for a bird to see in a sea of green foliage, after all.

What are 4 things needed for germination?
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
What softens the seed coat?
Keep plants in warm moist soil or unsterilized sand for several months to soften seed coats through microbial activity. Seeds may also be planted directly in the summer or fall while soil temperatures are warm.
What 3 things do seeds need to germinate?
Essentials
- The beginning of the growth of a seed into a seedling is known as germination.
- All seeds need water, oxygen and the right temperature to germinate.

What are 5 ways seeds are dispersed?
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.
How do you spread seeds?
Spread the seed evenly by hand in small areas. Use a hand or lawn spreader or a mechanical seeder in large areas. Apply approximately 16 seeds per square inch. Too many seeds too close together causes seedlings to fight for room and nutrients.

Animals help disperse seeds in a variety of ways. Edible fruits are eaten by birds and other animals.

The seeds are not fully digested, so animals then disperse the seeds through their droppings.
