Bio - Plants Flashcards

Terms Definitions
annual
1
anther
makes pollen
bryophyte
specialized reproductive organs
vascular
fluid movement tissue
Gametophyte
Haploid multicellular organism
spore production
sexual or asexual
external to vascular tissue
Cortex
Filament
supports the anther (male)
pith
internal to the vascular tissue
primary root
initial root from seed
Endosperm
(3n) nutrient supply for embryo
Chemical energy storage
-ATP and NADPH
sporangium
the structure where spores are produces
vascular bundle
xylem, phloem, and vascular cambium
roots serve as...
anchor plants, absorb H2O.
waxy layer that prevents water loss
cuticle
stolons
(runners or above ground horizontal stems, produce adventitious roots)
Root hairs
Help pull in more water
root nodules
masses of bacteria-infested root cells. Bacteria fix nitrogen and share with plant, plant shares sugars with them
NECTAR,
a sugary solution, to attract pollinators. It is stored in nectarines and is an energy rich food for pollinators
Prokaryotes
-lack nuclei, organelles, and sexual reproduction
--Bacteria and Archaea
Pines and other conifers can be distinguished from flowing plants in that pine wood
lacks:
Vessels
Pigment
Chemical that gives color and absorbs certain wavelengths of light energy
chitin cell wall
a tough, protective, semi-transparent, primarily a nitrogen containing polysecharide
angiosperms (flowering plant)
sporophyte stage, vascular tissue; perennials and annuals
circadian rhythms
24-hour biological cycles; inherent in all eukaryotic organisms
sepals
modified leaves that serve to protect the young flower
Sporophyte Genetics
Allows for diversity, stop harmful recessive traits from being expressed
Ground Tissue
Everything not dermal or vascular, where store or produce sugar
Vascular Tissue
tubes that transport water to plant
A short-day plant-
Flowers with a long night.
Cholenchyma cells
-serve to stiffen leaves and stems
(celery is rich in these)
sieve cells
living cells that lack nuclei and ribosomes; they transport sugars and other organic nutrients
wilting
dropping of leaves and stems as a result of cells becoming flaccid
Bryophytes (nonvascular plants)
gametophyte is dominant form; lack vascular tissue
photosynthesis
the process where "food" is made from light energy for the plant
self-pollination
occurs when pollen grains fall or are transferred from an anther to a stigma on the same plant
gametes –
Egg and Sperm cells within the plant
Pollination
The transfer of pollen from the anther to the stigma
epidermis
the layer of cells that make up the outer covering of a plant
Four divisions of the plant kingdom-
mosses and relatives(bryophytes), ferns and allies(pteridophytes), cone plants(gymnosperms), flowering plants(angiosperms).
alternation of generations
the alternation of two or more different forms in the life cycle of a plant or animal
specific heat
the amount of heat required to raise the temperature of a gram of that substance by 1 degree C. water has hig specific heat because of hydrogen bonds
Suberin
A waxy material found in cork and the casparian strip
apical meristem
end of all roots, tip of roots where growth happens
-internal conduction tissue developed-true leaves appeared-roots that funtion in absorption and anchorage developed-gametophytes became progressively smaller
4 things occured during early stages of vascular evolution:
in order for a seed to grow it needs...
moisture and temperature.
What are the 5 uses of cannibas?
Fibers, seed oil, seeds, medicinal, and recreational.
Know the symptoms of nutrient deficiency.
Lack of iron results in loss of chlorophyll and chlorosis. In severe cases, new leaves may appear white.
