2.It’s a complex mechanism of organism identification and may leads to chain of worng interpretations.  

3.The characteristics which are devised to identify an organism might not be a distinct feature of the species already exiting in the dichotomous key.

4.Dependency on physical characteristics, does not take into account genetic characteristics.

The seed consists of three components: embryo, endosperm (sometimes perisperm), and seed-coat. Both endosperm and embryo are the products of double fertilization, whereas the seed-coat develops from the maternal, ovular tissues. The seed habit is a significant advancement in the evolution of higher plants.

Anatomy of seed :-

Seed storage proteins provide a source of amino acids and reduced N necessary for germination and early growth of the seedling.

The maltose molecule can be broken down into two individual glucose molecules with the help of an enzyme produced within a cell.

D).increasing the pH with in the cell.

Explaination:

Consumers are dissatisfied with the way that large corporate  farms are treating nature's natural resources.

Fungi are a food source for animals and humans. Fungi produce oxygen to breathe. Fungi destroy rocks and minerals. Fungi are natural recyclers.
