What else can I help you with?
Give two ways by which pollen grains are scattered?
animal dispersal and wind dispersal
What is an anthropochore?
An anthropochore is a species which depends on arthropochory as a routine means of reproductive dispersal - the dispersal of seeds or spores by humans.
Sticky secretion on the scales of seed cones traps?
A sticky secretion on the scales of seed cones traps pollen grains. Structure is produced by a pollen grain that lands near an ovule is pollen tubes.
Is pollen a negatively or positively charged particle?
Pollen particles are not inherently classified as negatively or positively charged; their charge can vary depending on environmental conditions and interactions with other particles. Generally, pollen grains can exhibit both positive and negative charges due to the presence of various organic compounds on their surfaces. The charge can influence how pollen interacts with other particles in the air and can affect processes like pollen dispersal and allergenicity.
What do anthers and filaments re?
Anthers and filaments are parts of the stamen, which is the male reproductive structure of flowering plants. The anther is the pollen-producing tip of the stamen, where pollen grains are formed and released for fertilization. The filament is the stalk that supports the anther, elevating it to facilitate the transfer of pollen to pollinators or other flowers. Together, they play a crucial role in plant reproduction by enabling the dispersal of pollen.
Give two ways by which pollen grains are scattered?
animal dispersal and wind dispersal
What are Stalks that form pollen?
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
What do flowers produce?
A flower produce pollen sacs which has pollen grains in it
What dispersal mean?
dispersal means to scatter about or to separate
What is chance dispersal?
A means of dispersal that relies on chance.
What role does animals and wind have on pollination?
Animals and wind have a positive effect on polination because they help in dispersal of pollen grains.
What is the seed dispersal of grass?
I think it's zoochory(the dispersal of seeds by means of animals/humans)
What is pollen rate?
There is no such sense of a pollen "rate," but there is of a pollen count. Which means the average pollen grains in a cubic meter!
What happeneds during pollination?
A bee comes to drink some of the plants nectar and thus leaving some of the pollen that the bee picked up from another plant-Ha, what they said but basically it is the dispersal of pollen.
What are the 5 agents of seed dispersal?
air dispersal wind dispersal flying dispersal animal dispersal fur dispersal
2 parts of the stameN?
The stamen is composed of two main parts: the anther and the filament. The anther is where pollen is produced, while the filament is the stalk that supports the anther and positions it for optimal pollen dispersal.
Why tree emits pollen?
Trees emit pollen as a means to procreate.
