Biology

Systematics is one of the main fields of study in biology wherein the historical relationships of groups of biological organisms are studied. Through systematics, scientists are able to identify organisms existing in this world in accordance to their classification, group, phylum, and other hierarchical positions in the biological strata. Apart from studying the relationship of organisms with each other and in their environment, systematics also aims to determine patterns in the organism population where groups of organisms are most likely to thrive and survive. Systematics as scientific methodology in biology is essential to the establishment and maintenance of biodiversity. This is because through systematics, biodiversity existing in the Earth are identified and documented, converting these information into understandable / comprehensible and thereby useful information to other people. It is also a method and study where the life history of the Earth is documented. Systematics also makes it easier for scientists to identify or categorize new species of organism because of the strata that are identified and emerged from the study. Because of these important functions of systematics as a biological study, it contributes to biodiversity conservation because of the information obtained that will help people know what organisms will live and survive in a particular environment or habitat.

SPORANGIUM- hollow unicellular or multicellular structure in which spores are produced and from which they are released.

Amino acids are the building blocks of proteins. There are twenty (20) existing essential amino acids that are used to synthesize or make up proteins. These essential amino acids are the following:

Alanine (Ala) (A)

Arginine (Arg) (R)

Asparagine (Asn) (N)

Aspartic Acid (Asp) (D)

Cysteine (Cys)

Glutamic acid (Glu) (E)

Glutamine (Gln) (Q)

Glycine (Gly) (G)

Histidine (His) (H)

Isoleucine (Ile) (I)

Leucine (Leu) (L)

Lysine (Lys) (K)

Methionine (Met) (M)

Phenylalanine (Phe) (F)

Proline (Pro) (P)

Serine (Ser) (S)

Threonine (Thr) (T)

Tryptophan (Trp) (W)

Tyrosine (Tyr) (Y)

Valine (Val) (V)

Among these 20 amino acids, nine (9) of them are essential to a human's food diet. These amino acids are the following: histidine, isoleucine, leucine, lysine, methionine, phnylalanine, threonine, tryptophan, and valine. These essential amino acids are needed in the food diet for organisms to survive. These amino acids re mostly derived from food, such as plant seeds and some amino acids that are weak in plant seeds (such as lysine and tryptophan) are found in animal protein in foods….....
