NVCC COLLEGE-WIDE COURSE CONTENT SUMMARY
BIO 110 - GENERAL BOTANY (4 CR.)

COURSE DESCRIPTION

Emphasizes plant life cycles, anatomy, morphology, taxonomy, and evolution. Considers the principles of genetics, ecology, and physiology. Lecture 3 hours. Recitation and laboratory 3 hours. Total 6 hours per week.

GENERAL COURSE PURPOSE

This is a transferable one-semester, freshman-level course designed to:

A. provide the student with both a classical and practical understanding of plant science
B. provide the prerequisite to higher level courses in plant science curricula
C. offer an alternative to BIO 102 - "General Biology II’ by presenting similar topics from a botanical point of view

 

ENTRY LEVEL COMPETENCIES

Prerequisites: BIO 101 - "General Biology I" or equivalent. The entering student should know how to use a microscope and should have an average or above level of mastery of BIO 101 objectives. It is also recommended that the student be able to read and write on a college freshman level as measured by the English Placement Test.

COURSE OBJECTIVES

Upon completion of this course, the student will be able to:

A. describe evolutionary trends in the Kingdom Plantae and list differences between major taxonomic groups
B. describe the significance of evolutionary trends: from non-vascular to vascular plants; and from non-flowering to flowering plants
C. describe haplontic, diplontic and diplohaplontic life cycles
D. use vegetative structures of vascular plants as examples to describe, identify or know the functions of:

1. primary tissues, primary growth, secondary tissues, secondary growth
2. root morphology, root physiology and root modifications
3. stem morphology, stem physiology including modified stems
4. leaf morphology and physiology, modified leaves
5. vegetative reproduction: cuttings, grafts, tissue culture

E. describe the process of photosynthesis, including the anatomical structures involved, the physical components and the biochemical pathways
F. describe the morphology and adaptations of reproductive structures:

1. Anthophyta (angiosperms): flowers, modifications, pollination, fertilization, life cycle
2. Non-flowering plants: reproductive mechanisms, life cycles

G. describe seed morphology, seed germination and the factors which affect germination
H. describe the development of a vascular plant from seed to adult
I. describe the function and control of plant-soil-water relationships, including essential nutrients, soil, water movement, cohension, adhesion, transpiration, stomatal regulation, and adaptations to reduce water loss
J. apply nutrient and growth requirements to plant health/vigor: light, temperature, fertilizer, water and soil
K. cite the action of certain plant growth factors or hormones: auxins, cytokinins, gibberellins, abscisic acid, ethylene, phytochrome, hormone interactions, plant tropisms
L. give examples of typical plants in various biomes, ex. tropical rain forests
M. give examples of the ecological roles of plants: ex. on climate, the biosphere, oxygen-carbon dioxide balance, the carbon, nitrogen and water cycles, tropic levels, food chains, food webs, ecological succession and recolonization
N. cite examples of importance of plants to humankind in economics, aesthetics and recreation, science and technology, sociopolitical considerations, the world food supply, conservation and environmental quality
O. Plant evolution: cite index fossils of major phylogenetic trends.
