kingdom Plantae 15 Flashcards
plants are:
-cellular
-karyotic
produce how
multicellular
eukaryotic
sexually
what are plant cell walls made of
cellulose
vascular
vascular tissues carry water and minerals throughout the plant
non-vascular
lacks vascular tissue
are non vascular plants usually bigger or smaller
smaller and has a more simple structure
seed bearing plants
reproduce using seeds
non seed bearing plants
reproduce using spores
what are spores
tiny, one celled reproductive structures
what are seeds
an embryo of a plant with dipoid cells surrounded by a food source with a protective covering
how many phyla of plants are there
14
phyum bryophyta
mosses
phylum pterophyta
ferns
phylum coniferophyta
conifers
phylum anthophyta
flowering plants
are mosses vascular or non vascular
non vascular
are mosses seed bearing or spore bearing
spore bearing
what is a moss leafy shoot
a tiny stem with a very tiny leaflike structures
what is a moss rhizoid
a root like structure serving as an anchor
what is the first generation called
gametophyte
what happens in the moss gametophyte generation
a haploid spore is produced by meiosis
what is the second generation called
sporophyte
what happens in the sporophyte generation
begins with a diploid zygote. zygote grows into a mature plant forming spores and starting a new gametophyte generation
antheridia for mosses
sac like structure on top of the male gametophyte containing sperm
archegonia for mosses
case-like structure on top of the female gametophyte containing an ovum
when does the sporophyte generation begin
after fertilization
are ferns vascular or non vascular
vascular
are they seed bearing or spore bearing
they reproduce using spores
what are fern leaves called
fronds
what is the fronds blade called
petiole
fern rhizomes
they produce hair like roots ant anchor the plant and absorb water and nutrients
conifers are vascular or nonvascular
vascular
where do conifers grow seeds
inside the cone
male cones are called
pollen cones
female cones are called
seed cones
conifer trees are in which generation
sporophyte generation
cones are in which generation
gametophyte generation
what do angiosperms produce
seeds and flowers
what are the two categories of angiosperms
monocots and dicots
coyledons
still idk
what kind of roots do monocots have
fibrous roots that web out in different directions
what kind of roots do dicots have
one main root called a taproot
what kind of leaves do monocots have
leaves with parallel veins
dicots have leaves with
net like veins that branch out
monocots have flowers structures with multiples of
3
dicots have flower structures that form in multiples of
4 or 5
what are the two organ systems of angiosperms
shoot system and root system
what does the shoots system do
makes food for the pant and reproduces
what does the root system do
absorbs nutrients and water, stores food and anchors plant
what does the root system include
roots tubers and rhizoids
what are plant cell walls primarily made of
chiten
dermal tissue
outside protective covering of the plant that also allows for gas exchange and the absorption of minerals
ground tissue
provides storage fir water sugar and starch and also includes non woody stems and roots
vascular tissue
includes xylem and phleom
meristem tissue
made up of cells that are capable of continuing mitosis and responsible for on going growth and repair
where is meristem tissue likely to be foound
root tip stem tip and buds
