Pollen germination and growth can be controlled by environmental factors such as a decrease in bee populations. Other factors that can control it include human efforts.
A plant that produces too little gibberellins may exhibit stunted growth, reduced stem elongation, and delayed flowering. Gibberellins are important plant hormones that regulate various developmental processes such as germination, stem growth, and flowering.
Growers can intervene in a plant's life cycle by implementing techniques such as controlled pollination, where they manually transfer pollen to ensure successful fertilization. They may also adjust environmental conditions, like temperature and humidity, to optimize flowering and fruit set. Additionally, using growth regulators can help manage hormone levels to enhance fruit development and mitigate stress responses. These interventions can improve reproductive success and overall yield.
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.
Bats are well known mammalian pollinators. As the bat buries its face deep into the blossoming flower to get its nectar, the pollen sticks to the bat's face, specifically its facial hair, nose, lips and whiskers...and perhaps even the ears of smaller bats.
A bee transfers pollen from the anther to a stigma by visiting flowers to collect nectar and pollen as food. While foraging, pollen grains stick to the bee's body due to static electricity and the hairy texture of their bodies. When the bee moves to another flower, some of this pollen is brushed off onto the stigma, facilitating cross-pollination, which is crucial for plant reproduction. This process enhances genetic diversity in plants and promotes healthy ecosystems.
Adequate rainfall after a period of drought could trigger seed germination and growth in wildflowers by providing the necessary moisture for the seeds to break dormancy and start growing. A change in temperature signaling the arrival of spring could prompt seed germination and growth in wildflowers, as many seeds require specific temperature cues to start their growth cycle.
well it might not make a difference
To determine if the seeds that went to the moon have changed, scientists would compare their growth and development with control seeds that were not exposed to space conditions. They would analyze characteristics such as germination rates, growth patterns, and genetic expression. Additionally, examining any morphological or physiological changes under controlled conditions would provide insights into potential mutations or adaptations. Finally, molecular analyses, such as DNA sequencing, could reveal specific genetic changes that occurred during the lunar mission.

The name of a science experiment is generally a short phrase summarizing what you did in an experiment. For instance, if I tested how temperature affects bean germination, my title might be "The Effects of Temperature on Bean Germination."

because some flowers might have pollen and some people might be allergic to them
No, sperm cells do not grow out of a pollen grain. In plants, sperm cells are produced within the pollen grain, and they are involved in fertilization when the pollen grain reaches a female reproductive structure. Each pollen grain contains two sperm cells.
the pollen might stick to their clothes, hands/fingers and hair, which can be an easy source to find out where the person has been.
If you might have noticed a recent answer, which was pollen, that answer is wrong. Bees collect nectar, which they turn into honey. pollen sticks to their legs and falls onto other flowers. this is called pollination.
Germination is the process where a plant grows from a seedling to fruit or power. The science behind germination might refer to the amont of water, light, temperature and oxygen that certain seedlings need in order to grow.
So they can smell out pollen and food.
