Answer:
1 ans Our hypothesis is that the plant will die. We have two plants, one in the jar and one outside of the jar. Both are on the kitchen counter (I've included a link to the photo of the plants at the bottom of this post). We watered both plants prior to putting the one in the jar. Our thought is that the plant in the jar needs to be left alone for the duration (since it is in the jar, technically, we should not be opening the lid to water and such). We believe that eventually, the lack of nutrients (i.e. water, CO2) will kill the plant in the jar, while the plant outside the jar will thrive because it will be watered and will get CO2.

Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa). Frequently small in size and making negligible demands upon their environment, seeds are eminently suited to perform a wide variety of functions the relationships of which are not always obvious: multiplication, perennation (surviving seasons of stress such as winter), dormancy (a state of arrested development), and dispersal. Pollination and the “seed habit” are considered the most important factors responsible for the overwhelming evolutionary success of the flowering plants, which number more than 300,000 species.
3 ans In plants like Gloriosa superba, The leaf tips get elongated and become tendrils. In some plants like Lathyrus aphaca, the entire leaf gets modified into a tendril and the stipules expand to carry out the function of a leaf.
