How do angiosperms increase the likelihood that their embryos arc moved away from the parent
plant? Why does moving the embryos away from the parent plant increase the success of the
embryo?
Solution
Ans:
Angiosperms are the flowering plants and most are terrestrial and all lack locomotion. Gametes
are delicate single cells. For two plants to cross fertilize, there must be a mechanism for the two
gametes to reach each other safely. There must also be a mechanism to disperse their offspring
far enough away from the parent so that they do not have to compete with the parent for light,
water, and soil minerals.
Seeds from the parent plant need to be dispersed away from the plant to allow the seedlings a
chance at survival without having to compete with the parent plant for space, nutrients and
sunlight. Dispersion also allows the species to spread its population across a wider territory to
ensure its continued survival.
Explanation: When too many seeds are planted in the same pot or area, the seedlings tend to be
weaker and more fragile because they have to compete with the other seedlings for resources.
There are several ways in which seeds are dispersed naturally in plants. Gravity is sometimes
sufficient to pull down heavy seeds from tall plants. The seeds then roll away from the parent
plant and begin to grow. Animals also help with seed dispersion. The seeds can have surfaces
that facilitate their sticking to the fur or skin of the animals so they can be transported as the
animal moves around. When animals eat fruit containing seeds, the seeds pass through the
animals\' gastrointestinal tracts unaffected and are excreted at different locations along with
some fertilizer nutrients to help them grow. Some seeds are light enough or have special wing-
like adaptations to allow for dispersal by wind. Other seeds can float in water and move along
with streams to a new location where there are sufficient nutrients and no plants to compete with
for water and sun. Sometimes, seed pods burst with enough force that the seeds get thrown over
a distance to allow the seedlings to grow away from the parent plants. The numerous different
ways in which plants have evolved to perfect their technique of seed dispersion is a telltale sign
of how important it is for seedlings to grow away from the parent plants..
