Pollen is a fine to coarse powdery substance comprising pollen grains which are male microgametophytes of seed plants, which produce male gametes (sperm cells).
Is pollen considered a seed?
Pollens are very different from seeds because they are fine and powdery. They contain the microgametophytes or the gametes (comparable to the sperm cells) of seed plants. Because of this nature, pollens more specifically pollen grains require some magnification for one to see.
Is pollen a living thing?
In angiosperms, pollen is produced by the anthers of the stamens in flowers. Pollen consists of one or more vegetative cells and a reproductive cell. A pollen grain itself is not the male gamete.
Does pollen contain DNA?
To DNA barcode pollen, the first step is to extract the DNA. Pollen grains produce the male reproductive cells (sperm) of the plant. Each pollen grain has a tough outer layer called the exine, made of a protein called sporopollenin. We need to break the exine in order to release the DNA that’s protected inside.
What does pollen consist of?
Pollen grains are microscopic structures that carry the male reproductive cell of plants. The inside of the grain contains cytoplasm along with the tube cell (which becomes the pollen tube) and the generative cell (which releases the sperm nuclei). The outer shell is made of two layers.
