Pinto Bean Plants

Decent Essays

I started off with two dicot plants (pinto beans) and was able to observe the sprout. In both dicot seeds the root sprout first followed by the stalk. Once the plants had developed mature roots they were transferred to a pot of soil where they remained for the rest of their time. As time passed one of the pinto bean plants dried out and the other was fertilized producing a bean pod, which can be seen in the picture for week 14. This could have occurred because of the competition that plant faced for sunlight and water. The surviving dicot plant was the one that sprouted first of the two, possibly giving it a slight advantage over the other plant. Being the first to sprout allowed it to have more time to develop it roots as well as grow. The …show more content…

The cross-sections demonstrated the basic differences that distinguish a monocot plant for a dicot plant. When looking at the cross-section of the monocot stem you can see that the vascular bundles are scattered. These vascular bundles consist of only a phloem and xylem. The phloem is responsible for transporting soluble compounds (food) created by photosynthesis, to the rest of the plant, especially where they are needed. The xylem is important for the movement of water throughout the plant. Another difference that can be seen by looking at the cross-section of at stem is that the ground tissue (parenchyma) is not partitioned into pith and cortex. In the dicot stem cross-section the vascular bundles form a ring and they are made up of a phloem, xylem, and a cambium which divides the two. The ground tissue (parenchyma) for a dicot is separate into a pith (nutrient storage and distribution) and a cortex (conducting tissues). The Leaf cross-sections reveal the venation of each plant. For monocots, the veins appeared run parallel to each other, while the veins for the dicot plant had no clear pattern. The root cross-sections also displayed differences between the groups belonging to the phylum Anthophyta. The root cross-section of a monocot is formed by vascular bundles that are arrange in a ring. In the dicot root cross-section, the xylem is at the center in the form of an
