zygotic meiosis

meiosis occurs after fertilization

gametic meiosis

meiosis produces haploid gametes

sporic meiosis/alternation of generations

alternating between haploid/gametophyte and diploid/sporophyte generations

3 growth forms of lichens

crustose(flat), foliose(leafy), and fruticose(branching)

imperfect fungi

asexual reproduction only

perfect fungi

both sexual and asexual reproduction

parts of basidiomycota fruiting

cap, gills, stipe/stem, and basidia(reproductive cells)

slime mold

large multinucleate, forms plasmodium

apicomplexa plasmodium

protozoa, causes malaria, lacks plasmodium stage

composition of radiolarians

silica

composition of foraminiferans

calcium carbonate

dioecious

male and female reproductive organs on separate individuals

monoecious

male and female reproductive organs on the same individual

heterospory

male and female spores

homospory

one type of spore

calyx

sepals

corolla

petals

androecium

stamens (anther, filament)

gynoecium

carpels (stigma, style, ovary)

describe double fertilization

one sperm fertilizes the egg, while another sper, fuses with two polar nuclei to form endosperm

monocot

one cotyledon, parallel venation

eudicot

two cotyledons, net-like venation

stem

vasular bundles, xylem(up), phloem(up and down)

root

epidermis, cortex, vascular tissue

leaves

stomata, veins, mesophyll

role of auxin in leaf abscission/auxiliary bud development

auxin inhibits leaf abscission and promotes bud dormancy

gibberellins in stem elongation

gibberellins promote cell elongation in stems

light grown plants

larger, chlorophyll

dark grown plants

smaller, pale, lack chlorophyll/etiolated
