26
what are pigments
absorbs light energy
27
what is the main pigment found in plants
chlorophyll a
28
what does chlorophyll a do
absorbs all light but retracts green
29
what are some other examples of pigments
chlorophyll b and cartenoids
30
where is chlorophyll located at
in the thylakoids
31
how many steps of photosynthesis are there
2
32
what is the 1st step of photosynthesis
light dependent reactions
33
what happens during the 1st step of photosynthesis
light is captured and converted to chemical energy
34
where does photosynthesis occur at
in thylakoid
35
what does photosynthesis split
water molecule
36
what does photosynthesis create
ATP and NADPH
37
what does photosythesis make
glucose
38
what do cellular respiration break down
glucose
39
what is the 1st step reactants in photosynthesis
light water ADP NADP
40
what are the products for the 1st step in photosynthesis
oxygen ATP NADPH
41
what is the 2nd step for photosynthesis called
the calvin cycle
42
where does the calvin cycle occur
in the stroma
43
what does the calvin cycle do
regenerates the starting material with each turn and is the sugar factor within cholorplast
44
what are the reactants of the calvin cycle
carbon dioxide ATP NADHP
45
what are the products of the calvin cycle
sugar NADP ADP
46
what is used for cellular respiration, cellulose, starch and other organic compounds
glucose or sugar
47
what are plants important for
medicine food clothes
48
what was the cause of the 1845-1852 Irish Potato Famine
1 million people starved and emigrated
49
what part of the plant performs photosynthesis
leaf
50
what part of the plant supports the entire plant
stem
51
what are the 3 major transitions from algae to plants
gas exchange support from stem and roots the ability to withstand sun and protect itself from dehydration (prevent desiccation)
52
what is the major functions of roots
anchor plants absorb water and minerals from soil
53
what are the 4 important parts of a plant
reproductive structure (flower or fruit) leaf stem roots
54
where does the gas exchange occur
in the stomata
55
how does a plant prevent dessication
cuticle traps the water inside the plant to prevent dehydration
56
how is a plant supported
via vascular tissues
57
what is xylem and phloem
tubing that moves molecules
58
pholem flows
down
59
xylem flows
up
60
what does modified roots do
anchor and stabilize store nutrients increases surface area to absorb more water and nutrients
61
what does modified stems do
transport key molecules
62
what does a runner stem do
spreads out far
63
what does a rhizome stem do
store nutrients
64
what does modified leaves do
grab, poke and attract
65
what are the 4 major plant groups
bryophytes (moss) pteridophytes (ferns) gymnosperms (cone producers) angiosperms (flower producers)
66
what type of plants are angiosperms
flower producers
67
what type of plants are gymnosperms
cone producers
68
what type of plants are bryophytes
moss
69
what type of plants are pteridophtes
ferns
70
what order is the evolution of plants
algae --> bryophytes--> pteridophytes--> gymnosperms--> angiosperms
71
what are the parts of a flower
filament anther petals stigma style ovary ovule style sepal receptical
72
what does anther make
pollen
73
what does a filament hold up
the anther
74
what does the petals do
protects the flower provides color attracts pollinators
75
a petal is a modified
leaf
76
what is a style
tube structure that holds the stigma but also concentrates the pollen to the ovary
77
what does the ovary do
protects and holds the ovule
78
what does the stigma do
holds on to the pollen
79
what does the sepal do
provides structure to the petals before blooming
80
what is the receptical
base of the flower and is the central location where everything converges
81
the receptical is the basin
that supports the whole flower structure
82
why is there flower diversity
flowers evolve based on pollinators they attract
83
what is a perfect flower
flower that has both male and female parts in the same flower
84
what is an imperfect flower
a flower that has male and female parts in 2 separate flowers
85
how do flowers attract pollinators
visual smell UV trickery
86
what is the main attributes of bryophytes
produces spores
87
what is the main attributes of pteridophtes
has vascular tissue
88
what is the main attributes of gymnosperms
cone producers and breed on land through pollen
89
what is the main attributes for angiosperms
fruit and flower producers and breed on land through seeds
90
what are the male parts of a plant
stamen anther filament
91
what is the female structures of a plant
carpel stigma style ovule ovary
92
what part of a plant are neither male or female
petal sepal receptacle
