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.

How might having the anther atop a tall filament make it more likely plants will be pollinated?
The anther makes the pollen I think, but you might wanna check though.
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.
What are all the possible purposes for which a growing seedling might use the food stored in its cotyledons?
during seed germination its stored food is mobilized by
What survival mechanisms have plants developed?
plants have developed varius types of seed Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, when the probability of seedling survival is low. One important function of most seeds is delayed germination, which allows time for dispersal and prevents germination of all the seeds at same time. The staggering of germination safeguards some seeds and seedlings from suffering damage or death from short periods of bad weather or from transient herbivores; it also allows some seeds to germinate when competition from other plants for light and water might be less intense. Another form of delayed seed germination is seed quiescence, which is different than true seed dormancy and occurs when a seed fails to germinate because the external environmental conditions are too dry or warm or cold for germination. Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination. i got this info from wikipedia
What signal might be considered a growth stimulating signal for a yeast cell?
Ras2 might be considered a growth stimulating signal for a yeast cell. It stimulated PKA and MAPK activity in the cell.
List two possible environmental events that might have triggered seed germination and growth into wildflowers?
Length of days and sufficient water can trigger seed germination.
What is the science behind germination?
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.
How does salt water affect seed germination?
well it might not make a difference
What names an experiment?
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."

Why cant you bring flowers into a hospital?
because some flowers might have pollen and some people might be allergic to them
Does sperm cell grows out of a pollen grain?
i do think it does in humans but it might in plants.
What do honeybees collect?
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.
How can pollen be used to work out where people or objects have been?
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.
What is in milk that might affect plant growth?
milk contains calcium and that is what which might affect plant growth
Grows from the pollen grain to the ovule?
Pollen tubes grow from the pollen grains to the ovules. Lipids on the surface of the stigma stimulate growth of the pollen tubes. Self sterile plants prevent themselves from growing seeds by not creating these lipids.
