Diversity in living organisms plantae lvl 1 Flashcards
plantae classification
cryptogamae, phenerogamae
cryptogamae
thallophyta, bryophyta, pteridophyta
phenerogamae
angiosperms, gymnosperms
thallophyta contains
algae only (haploid)
algae are aquatic/terrestrial/else
all are aquatic
thallophyta body
fillamentous, mostlycolonial
thallophyta food?
by photosynthesis
thallophyta reproduction
by vegetative, asexual, sexual
thallophyta types
chlorophyceae - green - mostly fresh water
paheophycae - brown - cold sea
rhyadophycae - red - warm sea
brown is largest
thallophyta example
spirogyra, fucus, ulva
bryophyta are called
amphibions of plant kingdom
bryophyta place
damp and mosit
bryophyta were first-
landed and non vascular plants
are bryophyta complex
no they are simplest and smallest
bryophyta haploid?
main body is haploid - gametophyte
diploid stage - sporophyte
bryophyta sexual organs are
multicellular and jacketed
bryophytasexual organs type , ex
male - antherodium
female - archegonium
bryophyta male, female gametes
male - antherozoids
female - egg
bryophyta example
riccia, merchantia, funaria
pteridophyta were first
vascular plants
pteridophyta habitat
moist and damp
pteridophyta diploid?
main body - haploid - gametophytes
diploid - sporophyte
pteridophyta what is req for fertilisation
water
pteridophyta are called
reptiles of plant kingdom
pteridophta examples
horse tail, dryopteris, marsilia
gymnosperms have - seeds
uncovered
gymnosperms were first
seeded vascular plants
gymnosperms main body haploid?
main body diploid - sporophyte
gametophyte develope over sporophyte
gymnosperm pollination by?
wind only
gymnosperm ex
cycus, pinus
angiosperms have - seeds
covered seeds
angiosperms are first
flowering plants
angiosperm seed are covered in
fruit wall/ovary wall - pericap
more than - % plants are -
50% are angiosperms
angiosperms roots -
tap root - dicot
fibrous root - monocot
angiosperm repro. organ
flower
angiosperm main body
sporophyte
hardest substance in plant kindom is - found in -
sporopollenine, pollen grains outer cell wall
