PHOTOSYNTESIS

Here are the steps followed to observe the process of photosynthesis in a bean plant.

The first step was to prepare the materials and substances necessary for the experience

Day 1

Then we have to put cotton in the pan so it covers the bottom of this and moistened with a little water. Cotton is placed on this bean seeds, which will allow the observation that the photosynthetic process. This part of the procedure shown in the following photographs

Day 3

It notes that begin to emerge from the seed light green twigs and the bark begins to open, revealing two caps from where these branches. Added water to keep moist cotton

Day 6

This day is observed that the branches are longer and are twisted, the caps that are within the shell begin to open without separating, they are as attached to the branch. You begin to sprout little hairs that branch.

Day 8

It is noted that the shells of many of the seeds begin to detach from the caps that have the green branch, which has more white hairs. In one of the seeds has not passed anything, add water again to not let it dry .

Day 10

Some leaves were observed within the caps that are glued to the stem and the bottom are the roots and the plant looks better than being born. Gone were the shells of three of the 4 seeds that were placed. One of the seeds did not produce anything until today.

Day 14

There are already some plants because it leaves a little older, but still have the caps where the leaves came out. The roots are longer and are sticking to the cotton. Only three seeds grew well but did not all fast one was slower and more twisted stalks.

Day 15

The plants are larger and the leaves begin to open, the lids are beginning to peel the stem and roots stuck to the cotton. They have different sizes, all of a sudden because one took more water than others.

I could not finish watching was happening to the plants because I dropped the container and broke two of them, and yet lags in what I was seeing. Will place other seeds to see how the plants are.

I liked this job because I realized how plants are born.
