|
acidic soil |
plants prefer mildly acidic water without acidic rain the forests would die out |
|
|

protects the pollen |
|
|
apicial meristem |
plant tissue composed of actively dividing cells located at the roots of the plant |
|
|
biodiversity |
number and variety of species in an ecosystem |
|
|
capillary action |
helps water and dissolved nutrients move upwards |
|
|
carpel |
female reproductive organ in a flower |
|
|
chlorisis |
leaves turning yellow (caused by a lack of nitrogen of magnesium) |
|
|
cork cambium |
layer in woody plant that produces cork |

stems without wood only have vascular bundle |
|
|
lateral meristem |
plant tissue composed of actively dividing cells located at the stem and roots |
|
|
leaf functions |
photosynthesis gas exchange storage protection from predators |
|
|

parallel venatation |
|
|
eudicots |
branching network venentation |
|
|
nodules |
in the roots of a legume holds bacteria |
|
|
osmosis |
movement of water from a high concentration to a low concentration |
|
|
palisade mesophyll |
upper epidermis elongated and tightly packed contain chlorophylls |
|
|
phloem |
carries sugar to the plant |
|
|
photopigments |
give plants their green colour |
|
|
pioneer species |
first species to colonize during sucession |
|
|
pollen |
male gametophyte carried by wind or on the body of a pollinator |
|
|
primary growth |
plant growth from the apical meristem
|
|
|
primary succession |
starts from scratch on rock or mineral deposites |
|
|
root functions |
anchor plant and keep it upright absorbs water, nutrients and other carbohydrates |
|
|
root hairs |
epidermal cell that increases surface area of roots to help absorption |
|
|
root pressure |
helps water and dissolved nutrients move upwards |
|
|
secondary growth |
plant growth originating from the lateral meristem |
|
|
secondary succession |
succession after an existing community has been disturbed |
|
|
seed functions |
protects and nourishes embryo |
|
|
stamen |
male reproductive organ in a flower |
|
|
starch |
stored in the root so we won't loose starch in the winter containing the most energy |
|
|
stem functions |
connects vascular tissue in leaves to root raises and supports the leaves and reproductive organs stores water raises flowers and cones |
|
|
stigma |
receives pollen grains |
|
|
style |
leads to ovary |
|
|
succession |
gradual change in a species over time resulting in a change of biodiversity |
|
|
taproots |
main root, branches into many small ones |
|
|
temp vs leaves |
when the temp goes down the water in the leaves freezes therefore angiosperms loose their leaves |
|
|
leaves <3 toxins |
protection from predators treats disease |
|
|
translocation |
movement from leaves to other parts of the plant |
|
|
transpiration |
main driving force of water movement in a plant helps water move up |
|
|
vascular bundle |
long continuous strands of vascular tissue that consists of xylem and phloem |
|
|
vascular tissue |
responsible for circulation of water and molecules |
|
|
venation |
arrangement of the veins in the leaf |
|
|
xylem |
transports water no nuclei used to replace water lost during transpiration |
