Some pollen grains have a spiky surface to help them sticky to the bodies of insects.
Pollen grains come in different sizes depending on the plant species. Larger grains tend to be heavier and have a harder time being carried by wind, so they are usually found in plants that rely on insects for pollination. Smaller pollen grains are adapted for wind dispersal, allowing them to travel further distances.
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.
· 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
The size of pollen grains can vary depending on the plant species, but most are typically between 10 to 100 micrometers in diameter. Some larger pollen grains can reach up to 200 micrometers. Pollen grains are microscopic structures produced by seed plants for reproduction.
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.
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. By Lyn Le

Pollen grains are produced in vascular plants
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.
The stigma.
Other plant from the surroundings that has anther (produce the pollen grains) will fertilise the ovule. when the pollen grains landed on the stigma, the ovule is then fertilise.

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.
The stigma is the part of the plant that traps pollen grains.
Pollen grains are often called as microspores or male gametes. They are produced in pollen sacs present in pollen chambers in the anthers of the flower. They are produced due to repeated division of microspore mothercells and are haploid (n).
The size of pollen grains can vary depending on the plant species, but most are typically between 10 to 100 micrometers in diameter. Some larger pollen grains can reach up to 200 micrometers. Pollen grains are microscopic structures produced by seed plants for reproduction.
The style transports pollen grains into the, ovary then into the ovule.
