Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.

Description
Trait A: medium-tip leaves Leaves are narrower toward the tips, but don't come to a full point. Most of the water drains from the leaves.
Trait B: drip-tip leaves Leaves come to a sharp point, leading to thorough water drainage from the leaves.
Trait C: wide-tip leaves Water runs onto the leaves and tends to pool in pockets at the tips.
During natural selection, organisms with harmful traits are less likely to successfully reproduce than organisms with beneficial traits. Neutral traits don’t improve or hurt an organism’s chances for survival. So, they tend to persist in populations when environmental conditions are stable. If the environment changes, neutral traits could become harmful or beneficial depending on the situation.

In year 1, a population of rain forest plants has the following distribution: 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. You will simulate three years of this population: year 1, year 5, and year 10. How will the trait distribution most likely change over this time?

I suppose medium-tip leaves become much less over the years is due to the fact withinside the description it says "Most of the water drains from the leaves." And as we recognize fungus likes cool and humid weather. Let us suppose that this plant is large and lives in a completely humid forest, and due to the fact the leaves can not keep water, a maximum of the water might pass at the floor subsequent to it. As we recognize vegetation that might be tall might have an extended shadow, and a fungus can develop below the plant due to the water maintains leaking thru the leaves, the humid temperature, and the shadow of the plant.

Next, I suppose that the wide-tip leaves will maximum probably be capable of living on higher is due to the fact whilst it rains maximum of the water will visit the middle or stem of the plant. (Like withinside the aloe vera plant there may be a bit socket withinside the center of the plant for water to move whilst it rains.) This approach that there might not be as lots water dripping out into the soil. Therefore this means that the soil won't be watery sufficient for a fungus to develop.

Finally, I suppose the drip-tip leaves might be 2nd for the maximum probable capability of life on is due to the fact despite the fact that the rain will usually pass into the soil, however, a few will nonetheless pass into the plant. I'm now no longer pronouncing that the medium-tip depart might not however I suppose that the drip-tip depart might capture extra rain than the medium-tip depart.

What are fungal infections of plants?

It generally causes stress. it is caused by soil, seed, weeds are spread by wind and water.

Hence it concludes that rainforest plants are prone to developing fungal infections on their leaves.
