Alex was observing a specimen using a microscope they observed Mutiple cells in rows of that reassembled bricks or boxes they also noticed a nucleus in the middle of each cell. and the cell contained small organelles that were green in color Alex concluded they are looking at plant cells. what evidence from their observations best supports this claim
there were Mutiple cells
the cells had cell wall and chloroplasts
each cell had nucleus
the cells contained organelles
The evidence from their observations that best supports the claim that they are looking at plant cells is that the cells had cell walls and chloroplasts. Both cell walls and chloroplasts are characteristic features of plant cells.
whats the anwser than
The answer is: the cells had cell walls and chloroplasts.
The evidence from the observations that best supports the claim that Alex was looking at plant cells is the presence of cell wall and chloroplasts in the cells.
To arrive at this conclusion, Alex made several observations. First, they noticed that there were multiple cells in rows, indicating a cellular structure. This observation alone does not specifically suggest plant cells since other organisms, such as some types of bacteria, can also exhibit multicellularity.
The presence of a nucleus in each cell is another observation made by Alex. While a nucleus is a common feature in most eukaryotic cells, including animal cells, it does not exclusively indicate plant cells.
The crucial observation that supports the claim of plant cells is the presence of both cell wall and chloroplasts. Plant cells have a rigid cell wall made of cellulose, a complex carbohydrate that provides structural support. In contrast, animal cells lack a cell wall. Additionally, plant cells contain organelles called chloroplasts, which are responsible for conducting photosynthesis and giving plants their green color.
Therefore, given the combination of multiple cells, a cell wall, chloroplasts, and a nucleus, Alex's conclusion that they were observing plant cells is most strongly supported by the presence of cell walls and chloroplasts in the observed cells.
