Answers
Answer:
The three main parts are: the roots, the leaves, and the stem. Each part has a set of jobs to do to keep the plant healthy. The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves.
Many plants have seeds that use water as a means of dispersal. The seeds float away from the parent plant. ... If the seeds fall in the water, they are carried away by the tide to grow somewhere else. Kōwhai trees also use water dispersal.
Farmers spray to mitigate crop damage caused by pests. A pest is any biological organism, including weeds, pathogens, and arthropods, that interferes with the production of crops affecting quality and/or yield. ... Pesticides work in many different ways by affecting their target, whether it be a weed, pest, or disease.
