Walnut trees just simply let their seeds fall to the ground by encouragement of the wind or from animals like squirrels. Maple trees is more reliant on winds to take their seeds from the parent tree and carry them away where they can establish themselves. The wings on the maple seeds act like wings which can propel them through the air on the wind at quite a distance.
It is dispersed through splitting. However, the seeds can go further than other splitting plants as it has wing-like structure which allow itself to be carried away by the wind. =)
Pollen grainÊ has a water resistant covering and contains a male gametophyte part that can produce sperm. Sperms are carried as part of the pollen grain by gravity.

To aid dispersal of their larvae. To avoid desiccation. To provide food for crustaceans. To help stabilize oyster beds. Benthic invertebrates don't produce planktonic larvae.
it get's despersed easily when it flies through the air and seeds disperse in the atmosphere and produce a new plant
No. It also applies to grains and the pulse crops.
yes they are because their seeds don't have a covering or shell like a fruit. They produce cones and they don't produce flowers.
because of its covering.
Dispersal in bryophytes is via spores; they neither have flowers nor produce seeds. Bryophytes do produce gametes that fuse to form a zygote, which in turn develops into an embryo, but this is not contained in a seed as in gymnosperms and angiosperms.
It applies a small amount of force to produce a large amount of force.
The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds.
they should produce a written repot covering the aspect specified at the end of the lesson plan
