like any other organisms, plants reproduce their own kind. ___________ more varied and complete than human reproduction
plant reproduction
part of the shoot system specializing in sexual reproduction
flower
what are the three parts of a flower
pedicel (peduncle))
Receptacle (torus)
Appendages
_______ is the flower stalk
pedicel
______ holds the flower part
receptacle
what are the three appendages
Perianth
stamen
carpel
______ contains the sepals and petals
perianth
protects the flowers when in bud
sepals
attracts pollinating insects
petals
the male part of the plant
stamen
are lobes containing pollen sacs
anther
stalk that hold the anther
filament
female part of the plant
carpel
receives the pollen
stigma
supports the stigma
style
contains ovules that tore the female gamete
ovary
main axis is suppressed, becoming almost flat
capitulum/head
spike-like inflorescence that bears only unisexual flowers; occur only in woody plants
catkin
main axis is comparatively short.
corymb
consists of a cup-shaped involucres formed by fused heads
cyathium
main axis ends in a flower that opens before the flowers below or on its side opens
cyme
fleshy receptacle forms a hollow cavity which is more or less pear-shaped and has a narrow opening
hypanthodium
main axis of the flower is branched, and the lateral branches bear the stalked flower
panicle
an unbranched, elongated main axis whose flowers have pedicels that are all about the same length
raceme
spike with fleshy axis, enclosed by large, often brightly colored bract called SPATHE
spadix
elongated axis; flowers are sessile or without stalk
spike
primary axis is shortened and bears at its tip a group of flowers which have pedicels that are all about the same length
umbel
with a cluster of sessile flowers in the axil of leaf forming a false whorl at the node
verticillaster
what are the four types of pollination
self-pollination
cross-pollination
wind pollination
animal pollination
a type of pollination where it is a same flower or another flower of the same plant
self-pollination
a type of pollination; flowers from different plants
cross-pollination
a product of a fertilized ovule in angiosperms
seeds
a part of a seed; immature plant in which a new plant will grow
embryo
is known as the embryonic root
radicle
known as the seed leaf
cotyledon
shoot apex above the attachment of cotyledon
epicotyl/plumule
connects the radicle to the cotyledon
hypocotyl
a part of the seed; nutritive tissue that feeds the embryo
endosperm
a part of a seed; outer covering of the seed
seed coat
mature, ripened ovary that provides protection and dispersal for the enclosed seeds
fruit
types of fruit
simple and compound fruit
from a single carpel or fused ovaries of one flower
simple
a fleshy fruit where all layers are soft
berry
a fleshy fruit where the endocarp is leathery or papery
pome
a fleshy fruit where the exocarp is leathery
hesperidium
a fleshy fruit where the endocarp is hard
drupe
a fleshy fruit where the exocarp is a tough hard rind
pepo
split open along one suture
follicle
split open along two sutures
legume
characteristics of Brassicaceae family
silique
compound ovaries break into individual carpels
schizocarp
split open along multiple sutures
capsule
develop from a single flower with separate carpels
aggregate
from carpels of many flowers that grows closely on a common floral stalk
multiple
