Pollen and spore types can be compared between samples found at a crime scene and those collected from a suspect or their belongings. If the pollen or spore types match, it can suggest a connection between the suspect and the crime scene, potentially tying them to the location or the victim. This type of evidence can be used in forensic investigations to help establish links and build a case against a suspect.

What is another name for microsporangium?
In seed plants, a spore-producing structure that produces microspores, which can grow to become the male gametopyte is known as microsporangium.
What is the difference between a spore and a pollen grain?
Pollen grains are formed in the anthers by meiosis; seeds in the ovary by fertilizationPollen grains are very tiny, even microscopic; seeds may be as small as 1mm across to as large as 50cmPollen grains are a single cell (similar to sperm); seeds are multicellularIts function is to carry the male characteristics of the plant to fertilize the egg cell; seeds are there to develop into a new plant when the conditions are favourable
What is the difference between spores and pollen?
Spores are reproductive cells produced by fungi and some plants that can develop into new organisms. Pollen, on the other hand, is the male reproductive cells in seed plants that are responsible for fertilizing the ovule to produce seeds. Spores are more resistant and can survive harsh conditions, while pollen is carried by wind, insects, or animals to reach the female reproductive organs.
In seed plants the structure that encloses the male gametophyte and transports it to another plant is called a?
In seed plants, the structure that encloses the male gametophyte and helps transport it to another plant is called pollen. Pollen grains contain the male gametophyte, which is the microgametophyte. When released from the anther of a flower, pollen can be carried by wind, insects, or other pollinators to reach the female reproductive structures of another plant, allowing for fertilization.
Where do gymnosperm seeds develop?
Gymnosperm seeds develop on the surface of specialized structures called cones. These cones are found on the branches of gymnosperm trees and shrubs, and they protect the seeds until they are mature enough to be dispersed.
Is a pollen grain spore?
No, a pollen grain is not a spore. A pollen grain is a male gametophyte produced by seed plants for the purpose of reproduction, while a spore is a reproductive cell that can develop into a new organism without the need for fusion with another cell.
Are puffballs unicellular?
Pollen is not unicellular. This is because pollen is not yet living and is only acting like a spore would act.
WHAT IS THE FUNCTION OF THE GYMNOSPERM SPORE?
The gymnosperms produce megaspores and microspores. A microspore is the male spore and megaspore is the large female spore. The microspore undergoes mitosis to produce the multicellular male gametophyte. These male gametophytes are the pollen grains that are contained inside short pollen cones. The megaspore is the large female spore that undergoes mitosis to produce the multicellular female gametophyte that is housed in a large female cone.
What is the function of the spore of gymnosperms?
The gymnosperms produce megaspores and microspores. A microspore is the male spore and megaspore is the large female spore. The microspore undergoes mitosis to produce the multicellular male gametophyte. These male gametophytes are the pollen grains that are contained inside short pollen cones. The megaspore is the large female spore that undergoes mitosis to produce the multicellular female gametophyte that is housed in a large female cone.

Is spore hero for Wii wifi?
No Also many people think spore PC is wifi but it is not.
Is the air better in winter or summer?
I would think air quality in general would be better in the winter due to a lower pollen and mold spore count.
Why plants need pollen and spore?
Pollen is essential for plant reproduction as it carries male gametes to female reproductive organs for fertilization. Spores, on the other hand, are reproductive cells that allow certain plants like ferns, mosses, and algae to reproduce asexually and ensure genetic diversity. Both pollen and spores are crucial for plant survival and propagation.
Function of germ pore?
a pore in the outer wall of a spore or pollen grain through which the germ tube or pollen tube makes its exit on germination stoma, stomate, pore - a minute epidermal pore in a leaf or stem through which gases and water vapor can pass
What kind of spore becomes a pollen grain in seed plants?
The microspore after resulting from meiosis in the microspore mother cell become pollen grain. It takes place inside the anther lobe in the sporogenous tissue and the entire process is called microsporogenesis.
What do you call a cell with a hard protective coat around it?
spore
What are the spore games called?
