ABCTE Elementary MS - Life Science Exam
Questions And Answers (Guaranteed A+)
Levels of classification - Answer✔Kingdom, phylum, class, order, family, genus, species.
Carolus Linneaus - Answer✔Today's system of taxonomy and classification based in part on his
work; his system uses the genus and species name of an organism as its scientific name (names
are in Latin because the language is non-evolving and was well-known to most scientists at the
time); the purpose of the system is to avoid confusion with more common names.
Characteristics of plants - Answer✔Eukaryotic, multicellular, cell walls made of cellulose, roots
and shoots, autotrophic, and reproduce sexually and asexually.
Nonvascular plants - Answer✔Have simple conducting tissue that does not differentiate into
roots, stems, and leaves, i.e. mosses and liverworts.
Vascular plants - Answer✔Have tissue that is differentiated into roots, stems, and leaves to
facilitate the movement of water and other materials throughout the body of the plant.
Mesophyll - Answer✔Layer of specialized cells within leaves where most of the plant's
photosynthesis is performed.
Mitosis - Answer✔The copying and division of the genetic material in the nucleus followed by
cell division; occurs in the somatic (body) cells.
Meiosis - Answer✔A specialized form of mitosis, which occurs in the reproductive tissues only.
The basic steps are the same but with an extra division.
Bacteria - Answer✔Single-celled prokaryotic organisms (cells lacking a true nucleus); some of
which are capable of invading our bodies.
Viruses - Answer✔(Debatable) entities consisting of RNA in some type of protein coating;
capable of penetrating living cells in order to use the cell's biochemical resources to reproduce
themselves.
Exocrine - Answer✔Secreting externally (either ducts or skin).
Lymphocytes - Answer✔A type of white blood cell (with two categories: T and B cells).
Soil erosion - Answer✔The wearing away of the Earth's surface by wind, water, and other
means.
