Locard's principle of pollen, named after Edmond Locard, states that pollen grains can be transferred between people, objects, or locations during physical contact. By analyzing the types of pollen present at a crime scene or on a suspect, investigators can trace the movements and interactions of individuals, potentially providing valuable forensic evidence.
The bee sees pollen with its eyes. It carries pollen because the pollen stick to the hind legs!
the mixture of pollen and spores.
microsporangium
A pollen tube grows from a cell in the pollen and penetrates the style of the flower, allowing the sperm cells to travel to the ovule. This process is essential for fertilization to occur in plants.
Ungerminated pollen grain is inactive and has not started the process of fertilization, while germinated pollen grain has started growing a pollen tube towards the ovule for fertilization. Germinated pollen grain is actively involved in the fertilization process, while ungerminated pollen grain is not.
Basically, locards exchange principle or theory, simply put is: there is no perfect crime because the culprit always took something but just as likely, left something behind which may eventually lead to his/her identity. It actually more says that when two surfaces come in contact, there is always an exchange of material. Whether you realize it or not. It really has nothing to with crime in particular. Take it from me, I'm a crime scene technician.
Locard's principle of exchange states that every contact leaves a trace. This means that when two objects come into contact with each other, there will always be a transfer of material, such as fibers, hairs, or skin cells. This principle forms the basis for forensic science and is often used to link suspects to crime scenes through the analysis of trace evidence.
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.
I hate pollen! Pollen is annoying!!
There is no such sense of a pollen "rate," but there is of a pollen count. Which means the average pollen grains in a cubic meter!
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
No, the average number of pollen grains in a cubic meter of air is typically referred to as pollen concentration or pollen count, not pollen rate. The pollen rate could refer to the speed at which pollen is released or spread in the air.

Pollen does not have an antonym
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.
pollen bags are for collecting pollen from one plant and tranfering to another plant in order to breed.
