How stigma helps in the wind pollination?
Depending on the type of pollinators, the pollen grains may be sticky or light. Exine present on the pollen grains as the outermost covering layer is contributed by the tapetum cells. Reaching on the stigma after pollination, the stigmatic cells interact with the material of exine to determine the compatibility of the pollen to allow its germination for fertilization.
How is the stigma of a plant adapted to trap pollen grains and provide a place for them to grow?
The stigma is adapted to trap pollen grains through its sticky surface or specialized structures that can capture and hold the pollen grains. Once trapped, the stigma provides a suitable environment for the pollen grains to germinate and grow pollen tubes, which then transport the male gametes to the ovary for fertilization to occur. This process increases the likelihood of successful pollination and seed production in plants.
How do wind pollination occurs?
On maturity of pollen grains , the anther lobes burst open and the pollen grains released in large amonut are carried by wind to several meters away to settle on feathery stigma as in case of plants of grass family.
What came first electron microscope or light microscope?
compound light microscope - cell theory - electron microscope
What is another name for ordinary microscope?
A common term for an ordinary microscope is a light microscope, which uses visible light to illuminate and magnify specimens for observation.
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.
How are pollen grains adapted to help plant pollinations?
Pollen grains are adapted for plant pollination by being small, light, and easily dispersed by wind, water, or animals. They typically have a hard protective coating to withstand various environments and ensure successful delivery to the female reproductive organs of plants. Additionally, pollen grains often have unique shapes or structures that help them adhere to pollinators or specific female plant structures for successful fertilization.

To What type of microscope is the arrow pointing?
I'm unable to see images or arrows directly. However, if you describe the microscope or provide details about its features, I can help you identify its type, such as a light microscope, electron microscope, or fluorescence microscope.

How does an electron microscope differs from a light microscope?
The light microscope use the visible light; the electron microscope use an electrons beam.
What is another name for the light microscope?
Another name for the light microscope is the optical microscope.
What is a light microscope that has two more lenses?
A compound microscope
Are wind pollinated flowers petals small?
Yes, wind pollinated flower petals are small, because they do not need to be showy to attract insects.
What microscope has the word light in it's name?
A light microscope
