TOPIC 9- Diversity of Plants

evidence of shared ancestry between plants and green algae

gametes ploidy

haploid

zygote ploidy

diploid

zygote

divides by mitosis to produce sporophyte

sporophyte ploidy

diploid

sporophyte

multicellular organism where meiosis occurs to produce spores

-spore making plant

spore ploidy

halpoid

spore

produces gametophyte in a process called germination

-grows by mitosis

gametophyte ploidy

haploid

gametophyte

multicellular plant that makes gametes through mitosis

gametangia

archegonia

antheridia

male gametophyte that produces sperm

sporangia

haptophyte

liverworts

bryophyta

mosses

monilophyte

ferma

lycophyte

club moss

coniferophyte

cone-bearing trees

arthrophyte

flowering plant

non-vascular plants

hepatophytes and bryophytes

-sporophyte lack vascular tissue

seedless vascular plants

lycophytes and monilophytes

seed plants

arthrophyte (angiosperm) and coniferophyte (gymnosperm)

heterospory

megaspore

microspore

pollen cone

microsporangia of gymnosperms that produce microspores

ovulate cone

megasporangia of gymnosperms that produce macrospores (ovules) that turn into seeds (femal cones)

microgametophyte

megagametophyte

monocot

eudicot

sepal

outside leaves with the main purpose of protecting the flower bud

petal

brightly colored leaves with the purpose to attract pollinators

stamen

carpel

female whorl; made up of ovary, style, and stigma

microsporocyte of archegonia
