Why do pollen grains have spikes?

Answer 1

· Simply due to the location where the species is found.

· A coastal species may have a different pollen shape to help with things such as salt resistant while a species found inland will be more heat resistant.

· It just depends on the type of environment in which the plant has adapted.

It also has something to do with bees. Bees have to carry pollen therefore telling how honey is collected

Answer 2

The reason why some pollen grains have spikes is because of the plant species. It also may be because of where the plant was adapted.

Pollen grains have spikes also simply due to the location where the species is found.

It is located in the coastal species where pollen grains have a different pollen shape to help with things such as salt resistant while a species found inland will be more heat resistant.

It really just depends on the type of environment in which the plant has adapted.

Answer 3

Pollen grains have spikes on their surface to help them stick to insects or animals for pollination. These spikes increase the surface area for better adhesion and prevent the pollen from being easily dislodged during transport.

Answer 4

why do some pollen grains have rough or sharp, thorny surface

Answer 5

Insect-pollinated flowers have larger pollen grains so as to make it easy for the insets to carry them. Bees are the most common insects that facilitate pollination.

Answer 6

Rough pollen surface ensures better attachment with pollinators as well as the stigmatic lobes. Hence some pollen have rough or sharpthorn surfaces.
