Lecture 1. Intro to Plant Physiology Flashcards
(19 cards)
The science that studies plant
function.
Plant Physiology
Studies the processes that take
place within a plant.
Plant Physiology
What is going on in plants that
accounts for their being alive.
Plant Physiology
Plant function can be understood on the basis and principes of ________ and ________, which in turn rely on ________.
physics, chemistry, mathematics
Plants respond to…
- Light (photoperiodism)
- Temperature
- Gravity
- Nutrient and water availability
- Disease
General activities of plants
- Seed germination
- Growth (stems, roots, leaves, buds, etc.)
- Flowering
- Opening and closing of stomata
- Tropism
Defined as a community
of plants dominated by trees.
Forest
Result of physiological processes of
plants.
Forest Growth
The process of irreversible increase by cell division and enlargement, including synthesis of new cellular material and organization of sub-cellular organelles.
Growth
The process involving conversion of reserve materials intro structural materials.
Growth
The process of qualitative change in plants overtime, phasic in nature (vegetative and reproductive), which is controlled by various environmental and genetic factors.
Development
The production of new individual plants or offspring by sexual or asexual means.
Reproduction
The food and manufacturing process in green plants.
Photosynthesis
Combines CO2 and H2O in the presence of light to make sugar and oxygen.
Photosynthesis
The process through which plant leaves, stems, and roots consume oxygen and give off carbon dioxide.
Respiration
The process by which plant roots take in water and nutrients.
Absorption
The process by which plant lose water from leaves and stems through evaporation (stomatal, lenticular, cuticular transpiration).
Transpiration
The process by which food and nutrients are moved within a plant from one part to another.
Translocation
The process by which plant
increases in number (of individuals).
Reproduction
