undefined, object
copy deck
micropyle
the small pore in the seed that allows water absorbtion
vascular plants
plants that have vascular tissue
vascular tissue
an internal system of tubes that transport substances within the plant, it also helps with support
angiosperm
a plant that produces seeds that are inclosed in a fruit
ovule
female gamete
seta
the long filament that has a sporangia attached to the end
stomata
tiny openings or pores on the underside of a leaf
Intermediate plants
simple vascular tissue, mid size, use spores
embryo
the young plant that develops from the zygote
seed
structures that contain young plants inside a protective covering
woody stem
hard stems, maple trees have this type of stem
zygote
fertilized egg
stigma
tip of pistil
auxin
a hormone that speeds up the rate which a plant's cells grow
anther
top part of stamen often yellow
germination
the early growth stage of the embryo
What is a stems function?
it carries substances from the roots to the leaves and hold the plant up, it also holds the leaves up for photosyntheis
fibrous root
branching roots like in a tree
embryo
the young plant that develops from the zygote
petals
the leaflike structures which are used to attract insects
hilum
the scar on a seed coat at the location where it was attached to the plants stalk during development
cuticle
waxy water proof layer that covers the leaves of most plants
tropism
a plant's growth response toward (positive) or away from (negative)
rhizoids
small root-like structures that anchor moss
sporophyte
the stage in the life cycle of the plant in which the plant produces spores
hypocotyl
forms the stem and the roots
pistils
female reproductive parts
pollination
when grains of pollen fall on the stigma
annual rings
rings found in the trunk of a tree caused by the xylems growing pattern; one is formed each year
types of roots
two types: fibrous and taproots
fruit
the structure that the ovary eventually changes into
characteristics of seed plants
have vascular tissue and use seeds to reproduce
spores
a tiny cell that is able to grow into a new organism
sepals
protect the developing flower (bud)
seed coat
the protective covering of a seed
Complex Plants
flower/seeds/pollen, trees/shrubs, Vascular tissue, tall
epicotyl
forms the first leaves of the developing embryo
xylem
the vascular tissue that water and nutrients move through
bog
a very acidic wetland
Simple plants
non-vascular, very short,produce by spores, don't need soil, wet enviroments
seed parts
embryo, stored food, and a seed coat
mosses
low growing bryophytes
What is a roots function?
anchor a plant in the ground and absorb water and nutrients from the soil
gametophyte
the stage in the life cycle of the plant in which the plant produces sex cells or gametes
herbacious stems
soft stems, dandelions have this type of stem
flower
the reproductive structure for an angiosperm
tissues
groups of similar cells that perform specific functions within the organism
nonvascular plants
low growing plants that do not contain vascular tissue
root cap
a hard tip that protects the root from injury
fertilization
when the pollen tube is formed and sperm goes down the tude and fertilizes an egg
Characteristics of seedless vascular plants
have vascular tissue and use spores to reproduce
Plant Characteristics
they are all multicellular, autotrophs that are also eukaryotes
peat
layers of dead moss in a bog that are compress
transpiration
the process in which water evaporates from a plants leaves
tap root
on thick main root a carrot is this type of root
style
the thin stalk that holds up the stigma
stamens
male reproductive parts
plumule
the shoot of an embryo
How many types of angiosperms are there?
there are two types monocot and dicot
ovary
the protective vessel where the seed develops
dicot
an angiosperm with two cotyledons
bryophyte
simple plants ex: mosses, liverworts and hornworts
filament
the thin stalk that holds up the anther
What are the three important stimuli to which plants respond?
touch, light and gravity
What is the leaves purpose in a plant?
they capture the suns energy and carry out the food making process of photosynthesis
radicle
the very tip of the root
phloem
the vascular tissue that food moves through
What do plants need to survive on land?
be able to obtain water and other materials, retain water, transport materials inside themself, support their bodies,reproduce succesfully
sporangia
the tiny structures in which spores are produced
hormone
a chemical that affects how the plant grows and develops
cotyledons
the seed leave in which food is stored
monocot
an angiosperm with only one cotyledon
gametes
sperm and egg cells
angiosperm characterisitics
they produce flowers and fruits
