Plants Grow Taller Through Mitosis at the Tips of Their

Multiple Choice

Plants grow taller through mitosis at the tips of their shoots (above ground) and at the tips of their roots (below ground) . Here are two samples of tissue taken from a grass plant, one from the tip of the root and one from the mid part of the plant.
$\begin{array} { | l | l | l | } \hline \text { Stage } & \text { Sample 1 } & \text { Sample 2 } \\\hline \text { Interphase } & 74 \% & 98 \% \\\hline \text { Prophase } & 18 \% & 0.5 \\\hline \text { Metaphase } & 4 \% & 0.2 \% \\\hline \text { Anaphase } & 2 \% & 0.1 \% \\\hline \text { Telophase } & 1 \% & 0.1 \% \\\hline\end{array}$
-What can you conclude from these data?

A) Sample 1 is likely from tissue in the middle of the plant because most cells are in interphase.
B) Sample 2 is likely from tissue in the middle of the plant because there are fewer cells in telophase than are in prophase
C) Sample 2 is likely from tissue in the middle of the plant because fewer cells are in any mitotic stage.
D) Sample 1 is likely from tissue in the middle of the plant because fewer cells are in any mitotic stage than in sample 2.
