COURSE TITLE: Biology I (Botany)

COURSE CODE: BIO 192

CREDITS: 4

CONTACT HOURS: 5 (3 lecture, 2 lab)

CATALOG DESCRIPTION:

An introduction to the biology of plants and their ancestors. Topics include cell structure and function, cell chemistry, photosynthesis and cellular respiration. The tissues, roots, stems and leaves are studied covering such topics as conduction, absorption, translocation and reproduction. A phylogenetic comparison among plant groups and their ancestors is the underlying theme. (May be taken independently or as a part of a two course sequence with BIO 193.)

(3,2) 4 credits

REQUIRED TEXT: Botany by Rost, Barbour, Thornton, Weier Stocking

Laboratory Book: Blueprint of the Plant, 2^nd edition, by Trakimas, Brown and Rachele

REQUIRED SUPPLIES: Laboratory voucher to be purchased by each student from Auxiliary Services at Roosevelt Hall.

BIO 192 COURSE OUTLINE

Lecture Schedule:

1. Introduction and History: attributes of life/characteristics of plants vs. animals

2. Classification of plants: artificial vs. natural systems/binomial nomenclature/five kingdom concept

3. Cell structure and function: cell theory/prokaryotic vs. eukaryotic cells/parts of cells...cell wall, protoplasm (organelles), ergastic substances

4. Cell chemistry: inorganic compounds...water, acids, bases, salts, minerals/organic compounds...carbohydrates, fats and lipids, proteins, nucleic acids

5. Cell division: mitosis/meiosis

6. Tissues: temporary..meristems, cambiums, pericycle.../permanent...epidermis, parenchyma, chlorenchyma, collenchyma, sclerenchyma, cork, xylem, phoem, cortex

7. Roots: structure and function: absorption, diffusion, osmosis, conduction

8. Roots: primary and secondary development: herbaceous vs. woody roots

9. Stems: structure and function

10. Stems: modified stems: tubers, rhizomes, stolons, corms, bulbs, spurs, thorns vs. spines and prickles

11. Stems: primary growth: monocots vs. dicots

12. Stems: secondary growth: softwoods vs. hardwoods

13. Leaves: structure and functions

14. Photosynthesis: photophosphorylation and carbon cycle/energy transfers...leading to a discussion of:

15. Respiration: aerobic vs. anaerobic

16. Transpiration: stomatal regulation and distribution/ other water conserving features of plants

17. Flowers: sexual reproduction/pollination, double fertilization, seed and fruit formation

18. Fruits: classification

19. Seeds: monocots vs. dicots
