The right answer is The plant cell wall provides a more rigid structure.
Plant cells are differentiated from animal cells by the cell wall (among others, they differ in size, vacuoles and the presence of chloroplasts).

Both dicots and monocots belong to the angiosperms. The angiosperms (the flowering plants) are divided into two classes - the dicots and monocots. Some of the main differences between these two groups are:
- The monocots have only one cotyledon in the seed while the dicots have two cotyledons in the seed.<span>
</span>- The monocots have <span>parallel leaf veins while the dicots have reticulated leaf veins.
- The monocots have </span>petals in multiples of three while the dicots have petals in multiples of four of five.
<span>- In the monocots, secondary growth is absent. In the dicots, secondary growth is often present.</span>
I believe the correct answer would be C.) The 3’ end has a free phosphate group
Answer:
double helix, which is made up of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).
