How does bee pollen exhibit antimicrobial activity?
pollen contain large no of primary and secondary metabolite and that metabolite are known for defence properties / mechanism therefore pollen having antimicrobial properties.
What are the two types of pollen?
The two types of pollen are wind-dispersed pollen and insect-dispersed pollen. Wind-dispersed pollen is typically small, light, and produced in large quantities, while insect-dispersed pollen is often larger, heavier, and designed to stick to insect bodies for transport.
What do animals bring flowering plants?
They bring pollen to the plants. Some bring pollen on pupose eg: Bees; Some bring pollen by accident eg: Deer, Bear, and other large or small wildlife
A conifer that has both male and female cones will produce many more pollen grains than ovules How does that help the conifer reproduce?
The wind usually scatters the pollen grains of conifers. The likelihood of pollen reaching female cones is increased when there are large amounts of pollen.
How does pollen use the air?
Some plants, like grasses and certain trees, do not use insects to carry pollen. Instead they produce large amounts of very small pollen grains which are released into the wind for them to be carried to other plants. Very often, it is this pollen which causes hay fever.
Is pollen an electron or proton?
No. It is neither. Of course, like any large chunk of matter, it has both.
How do both the bee and the plant it visits benefit from pollination?
Bees: special hairs on their legs and abdomen allow them to collect large amounts of pollen Plants: transfer pollen to other plants
What is the cause of a large-scale Yellow snow weather effect?
A large-scale Yellow snow weather effect is caused by the presence of excess pollen or dust particles in the atmosphere. These particles can get mixed with snowflakes as they fall, giving the snow a yellowish hue.
Would you expect pollen grains of wind -pollinated flowers to be sticky?
The pollen grains of wind pollinated plants are generally smooth and light. These are not sticky to avoid clump-sing. These are produced in large numbers to ensure landing some pollen on the feathery or netted stigmas.
Why are pollen grains produce in large nos?
PollenPollen is made as a plants way of reproducing, the pollen from one plant must mix with the flower of another in order to bear fruit or seeds. Since plants and trees are spread over vast areas, huge quantities of pollen must be released to be sure that it reaches another plant of its kind and as many of them as possible.
Why doesva flower have so many pollen grains than ovules?
flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
How do pollen grains contribute to air pollution?
Pollen grains can contribute to air pollution when they are released in large quantities into the air. This can happen during pollen seasons when plants are in bloom. Pollen grains can combine with other air pollutants like dust or industrial emissions, leading to increased levels of particulate matter in the air, which can exacerbate respiratory issues in sensitive individuals.
