BPHOTOSYNTHESIS
aThe process by which plants make their own food.
1Capturing Light Energy:
aChloroplast organelles in which photosynthesis takes place
bChlorophyll is the green pigment
2Making Sugar:
aCarbon Dioxide + Water light Energy Glucose + Oxygen
bSugar = Glucose
cCellular Respiration: The process by which cells use oxygen to produce energy from food.
dOxygen + Glucose energy Carbon Dioxide + Water
3Gas Exchange:
aPlant surfaces are covered by a waxy cuticle
b**Stoma-openings in the leaf’s epidermis
c-stoma are surrounded by guard cells
d-Transpiration: loss of water from leaves
ePlants and other photosynthetic organisms form the base of nearly all food chains
fRely on cellular respiration to get energy
gCellular respiration requires oxygen
CREPRODUCTION OF FLOWERING PLANTS
1Sexual Reproduction
aPollination happens when pollen is moved from anthers to stigma
bUsually wind or animals move pollen
cAfter fertilization the ovule develops into the seed.
dThe ovary surrounding the ovule becomes the fruit. **
eWhen seeds are dormant, they are inactive
fGermination or sprouting
2Asexual methods:
aPlantlets-tiny plants grow along the edges of a plant’s leaves. These plantlets fall off and grow on their own.
bTubers- underground stems, or tubers, can produce new plants after a dormant season.
cRunners – above-ground stems from which new plants can grow.
DRESPONSES TO THE ENVIRONMENT
1Environmental Responses
aTropism – growth in response to a stimulus
bPhototropism – change in the direction a plant grows that is caused by light.
cGravitropism – change in the direction a plant grows in response to gravity.
dHydrotropism –change in the direction a plant grows that is caused by water.
2Season Responses
aPlants respond to change in the length of day.
bAs fall and winter approach, days get shorter and nights get longer.
cAs spring and summer approach, days get longer and nights get shorter.
3Leaf Loss:
aEvergreen trees: shed their leaves year-round a little at a time so that some leaves are always on the tree.
iExamples: Pine Trees
bDeciduous trees: lose all of their leaves around the same time each year.
iExamples: Apple Trees
