Fernando is looking at a cell under a microscope, and he thinks it is a plant cell. Which of the following questions could he ask to determine whether or not it is a plant cell?

Well, first he could look at the cell wall. Animal cells don't have cell walls, so if he saw one he could say it was a plant cell. Plant cells also have chloroplasts, which animal cells don't have. So he could ask : Are there any cell walls in the cell? and Are there any chloroplasts present?

Explanation:

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
