How many and what are the processes that seed plants use to reproduce.
Luba_88 [7]
Plants reproduce through the process of fertilisation. Fertilisation is the process where female and male cells join together to form an embryo inside the seed. The seed protects the embryo in preparation for germination when conditions permit the plant to produce new plants.

Seed plants are classified into two types to determine reproduction. First are the Angiosperms, this type of seed plant has flowers that have special structures for reproduction. Pollens are made by male cells, while ovules are made by female cells. Pollens are carried out through the process of pollination (e.g. wind blows, insects carrying pollen). Most angiosperms that don’t undergo pollination develop intro fruits. If it goes into pollination they become new flowering plants.
<span>
Second classification is the Gymnosperms, which are seed plants that are held in cones. Gymnosperms like Angiosperms also have male and female reproductive cells. Reproduction also occurs through pollination but most gymnosperms are trees. The best example of a gymnosperm are pine cones.  </span>

If you are performing this test on an unknown organism why is it a good idea to run simultaneous
AlexFokin [52]
The question seem to be incomplete but I found the complete question which is:
If you are performing this test on an unknown organism, why is it a good idea to run simultaneous tests on known phenylalanine-positive and phenylalanine-negative organisms?

Here is the Answer:

Inoculation of a positive control and success from it includes certainty to negative outcomes on an unknown organism. That is, you know the test is working effectively, so the negative outcome is most likely precise. Without the positive control, there is dependably a component of uncertainty whether the negative outcome is a genuine negative or a false negative. performing the test on a known phenlalanine-negative organism is valuable in that it exhibits what a negative outcome looks like.
