PSS EXAM 1 QUESTIONS WITH CORRECT ANSWERS 100% SOLVED| GUARANTEED SUCCESS
Stomata the small openings on the undersides of most leaves through which oxygen and
carbon dioxide can move
opposite leaves identical leaves on either side of the stem, 2 leaves at node
alternate leaves leaves alternate every other on either side of the stem, 1 leaf at node
whorled leaves leaves circle around the stem, more than 2 leaves at node, unusual
Spine leaves that have been modified into cylindrical, hard structures with sharp ends, used
to protect themselves from herbivores
fertilizer burn leaf scorch resulting from over-fertilization, usually referring to excess
nitrogen salts
Translocation transport of food or pesticides through phloem or xylem
photosynthesis process that converts carbon dioxide into organic compounds, sugars, using
the energy from sunlight, oxygen is a waste product, occurs in chloroplasts. uses chlorophyll,
light and enzymes.
,Respiration reverse of photosynthesis. converts biochemical energy from nutrients into ATP
and then release waste product. uses glucose and oxygen to produce carbon dioxide and water
Aerobic respiration oxygen is available, produces high energy
Anaerobic respiration oxygen is not available, produces low energy. alcohol builds up
fermentation- kills roots
ATP transports cehmical energy within cells for metabolism
Carbon Dioxide end product in respiration, necessary to go through photosynthesis
oxygen end product of photosynthesis, necessary for respiration
Metabolism breaks down organic matter, uses energy to construct components of cells such
as proteins and nucleic acids
Transpiration loss of water vapor, leaf surfaces are dotted with stromata to release it
Pedicel stalk supporting a flower
, Receptacle portion of a compound flower where numerous flowers sit
sepals green, leaflike part of the plower that covers and protects the flower bud before it
opens
Petals flower immediately surrounding the reproductive organs
Corolla where the petals are fused together (petunias)
Stamens the male part of a flower
Anther holds pollen
Filament stalk that holds the anthen
Pistel female parts
Stigma sticky stigma surface catch pollen
Style tube from stigma to ovary
