25
Vascular tissue transports
water, minerals and organic compounds.
26
xylem transports
water and minerals
27
phloem transports
photosynthetic products
28
allows for the transport of water, minerals, and sugars.
vascular system
29
carries sugars from photosynthesis throughout the plant.
Phloem
30
contains specialized cells.
Phloem
31
have holes at ends
sieve tube elements
32
helps sieve tube elements
companion cells
33
unlike xylem, phloem tissue
alive
34
There are two main types of roots.
Fibrous root systems, Taproot systems
35
have one main root.
Taproot systems
36
have fine branches.
Fibrous root systems
37
support plants, transport materials, and provide storage.
Stems
38
form the support system of vascular plants.
Roots and stems
39
grow underground for storage
Stems
40
anchor plants and absorb mineral nutrients from soil.
Roots
41
covers the tip
root cap
42
an area of growth
apical meristem
43
contains xylem and phloem
vascular cylinder
44
absorb light and carry out photosynthesis.
Leaves
45
surround each stoma.
Guard cells
46
Leaf margins may be
toothed, entire, or lobed.
47
Leaf veins may be
parallel or pinnate.
48
increases a plant's length.
Primary growth
49
increases a plant's width.
Secondary growth
50
Leaves may be
simple, compound, or double compound.
51
help determine the age of a tree.
Tree rings
52
can be woody, and form protective bark.
stem
53
Pieces of tissues from one plant are placed on a sterile medium and used to grow new individuals in mass numbers.
Tissue Culture
54
arise from axillary bud on very short stem with thick fleshy leaves (only in monocots).
bulb
55
New shoots arise from axillary bud on swollen, short, fleshy, underground stem.
Tuber
56
Has both male and female sex organs
Hermaphrodites
57
Leaves or pieces of stems or roots are cut from one plant, planted in soil and used to grow new individuals.
Cutting
58
Small stems from one plant are attached to larger stems or roots of another plant.
Budding and Grafting
59
Also called as stolons
Runner
60
New plants arise at nodes of above - ground horizontal stem.
Runner
61
New plants arise at nodes of underground horizontal rootlike stem.
Rhizomes
62
It is often faster than growing plants from seeds. This method involves a little help from human by using a piece of plant material.
Artificial Propagation Method
63
New plants arise from very short, thickened underground stem with thin, scaly leaves.
Corns
64
Type of reproduction in plants from its vegetative parts or specialized reproductive structures.
VEGETATIVE REPRODUCTION
65
Occurs when pollen iS carried from the stamen to the stigma of the same plant.
Self Pollination
66
Occurs when pollen is carried to the stigma of another plant.
Cross Pollination
67
pollen that grows into the stigma, down the style and into the ovary.
Pollen tube
68
a swollen and ripe ovary which contains one or many seeds.
Fruit
69
a reproductive structure in which a plant embryo and a food source is contained.
Seed
70
a strong tissue that protects and surrounds a seed.
Seed Coat -
71
male reproductive part
Stamen
72
makes pollen grains
Anther
73
holds up the anther
Filament
74
female reproductive part.
Pistil
75
top part of the carpel
Stigma
76
joins the stigma and the ovary
Style
77
contains the female sex cells
Ovary
78
Transfer of pollen grains from the stamen to the stigma of a flower.
Pollination
79
process wherein the seeds together with its fruit are carried away from the parent plant.
Seed Dispersal
80
a process in which a new plant grows from a seed.
Germination
81
tiny plant, which is the youngest stage of plant growth.
Plant Embryo
82
one of the modified leaves.
Sepal-
83
one of the soft, colorful parts of a flower.
Petal-
84
the end part of the flower stalk upon which the floral organs are born.
receptacle-
85
a stalk bearingS flower
Peduncle-
86
Agents of Pollination
Wind • Water • Bees • Bats Birds
87
from seed germination to maturity, involves a combination of cellular responses and molecular interaction.
Plant growth,
88
Does not involve the fusion of gametes.
Asexual
89
Requires only one parent.
Asexual
90
Offspring are genetically identical to parents.
Asexual
91
Offsprings are clones.
Asexual
92
Involves fusion of sex cells to form zygote.
Sexual
93
Requires two parents.
Sexual
94
Offsprings show variations
Sexual
95
Transmission of characteristics.
Sexual
