TermDefinition
nonvascular plant
vascular plant with seed
vascular plant non-seed
meristematic tissue
epithelial tissue
connective tissue
muscular tissue
nervous tissue
parenchyma(simple tissue) PARENT
most common cells in plants -photosynthesis, support, storage transport
collenchyma(simple tissue) COLON
found near surface of stems, leaf petioles, veins -support to young plant organs
sclerenchyma(simple tissue)
thickened cell walls, may contain lignin-> polymer for strength (fiber) -structure, support, protect seeds (SSS)
complex tissue
composed of many cell types
simple tissue
composed of one cell type
xylem(complex tissue) XYLOPHONE
transport water and minerals from roots to leaves(one way)
phloem(complex tissue) PHO=2
transport products of photosynthesis throughout the plant(two ways)
ground(complex tissue)
consists of parenchyma, collenchyma, and sclerenchyma cells -photosynthesis, storage, structural support
dermal(complex tissue)
composed of epidermis, guard cells, trichomes, root hairs
epidermis
covered by waxy cuticle
trichomes COMB
hair that provides protection
Angiosperms
flowering plant -seed plants have reproductive structures (fruit + flowers) -after fertilization-> ovary becomes fruit -fruit protects embryo from desiccation + helps in dispersal by wind and animals
in angiosperms, where do seeds develop?
seeds develop from ovule
seed characteristics of angiosperms
enclosed + protected inside ovaries of parent sporophyte plant
angiosperm: FLOWERS
attract pollinators +reproductive structures
angiosperm: CARPELS
protect ovule, then develop into fruit
double fertilization
produce embryo + food source(endosperm)
endosperm
provide nutrients for developing embryo
reduced gametophytes
reproduction less dependent on water, allow efficient reproduction
pollen
carries sperm to egg
MALE PLANT STRUCTURE
STAMEN ^anther=produce pollen ^filament=support anther
FEMALE PLANT STRUCTURE
PISTIL ^carpel ^stigma=sticky surface that receives pollen ^style= connect stigma to ovary ^ovary=contains ovules ^ovules=contains female gametophyte/egg
sepals
protects developing flower
receptacle
supports flower structure
angiosperm reproduction cycle
2n plant → meiosis → n spores → n gametophytes → n sperm + n egg → 2n embryo n sperm + n + n polar nuclei → 3n endosperm DOUBLE fertilization = 2n embryo + 3n endosperm.
porifera (sponge)
multicellularity(animals) , NO TRUE TISSUES
cnidaria(jellyfish)
tissues, radial symmetry
flatworms
bilateral symmetry, NO body cavity
Rotifera
pseudocoelom( not completely lined by mesoderm, similar to nematoda), FIRST body cavity
nematoda
molting(shed outer cuticle for growth+development), pseudocoelom
true coelom, protostome development
segmentation(metamerism), division of body
jointed appendages, molting
echinodermata
deuterostome development(during embryonic development, blastopore became anus)
chordata
notochord, segmentation, jointed appendage
Kingdom Animalia
-multicellular eukaryotes that LACK cell walls -heterotrophic(require C & N for development) -cells organized(except Porifera) -reproduce sexually -majority of life in diploid stage
Radial Symmetry
central axis
Bilateral Symmetry
straight down
diploblastic (cnidaria)
2 ectoderm+endoderm
triploblastic
3 ectoderm, endoderm,mesoderm
SPONGE
NO TRUE TISSUE NO SYMMETRY
ectoderm (outer skin) EXIT DERMATOLOGY
become epidermis and nervous system
endoderm( INNER SKIN)
lining of digestive tract(gut)
become muscle, reproductive organs, circulatory, skeletal
acoelomate (a=without)
NO COELOM
coelomate
coelom with direct mesoderm
pseduocoelomate (pesudo=false)
lacks mesoderm directly around coelom
sac-like gut
gastrovascular cavity, mouth
tube-within-a-tube
mouth to anus
open circulatory system
blood flow freely in body cavity
closed circulatory system
blood contained within vessels
simple diffusion
gas pass straight through skin(NO ORGAN NEEDED)
gills
feathery organs that take O out of water
lungs
internal air sacs, O in blood-> blood delivers to cells
tracheal system
air tube carry O straight to cells (air enter through spiracles)
Excretory system
Simple diffusion, osmoregulation, kidneys,nephridium, flame cells, Malpighian tubules, etc
osmoregulation
control water and salt in body, NO ORGAN
kidneys
filter blood, remove waste
nephridium
paired tubes in each segment collect waste from coelom fluid +release it outside (ANNELIDS,MOLSUCS)
flame cells
tiny climated cells in pores, filter waste, regulate water (FLATWORMS)
Malpighian tubules
tubes attached to gut, pull waste from blood+dump to gut->feces,
locomotion
Flagella, cilia, crawling, or appendages
flagella
whip like tail(moves water), SPONGE or SPERM(single celled)
cilia
tiny hairs (FLATWORMS)
crawling
muscle contractions (clams)
appendages
limbs or outgrowth (arthropods, vertebrae)
support system
endoskeleton exoskeleton hydrostatic skeleton
endoskeleton
bone cartilage, hard support IN body
exoskeleton
hard shell/covering on OUTSIDE (clam)
hydrostatic skeleton
fluid held under pressure inside cavity(NOT HARD, earthworms, clay worms)
segmentation (worm vs beetle)
multiple body parts
appendages
feeding, fighting, fleeing, feeling, production
nervous system
Neural net, neurons, sensory organs or nervoussystem (CNS/PNS)
neural net
neuron spread evenly through body
neurons
individual nerve cells send electrical signals
sensory organs
detect environment (eyespots)
CNS=central nervous system
process info
PNS=peripheral nervous system
carry signal to and from
meristematic
