Q

pletiva kryci - sveraci

A

kdyz ma rostlina nedostatek vody tak se neuplne sevrou - zpomali se fotosynteza , jsou ze spoda listu , u rostlin na hladine vody - nahore

25
pletiva vodiva a zpevnovaci
nejznatelnejsi v listech - žilky, bunecne steny vystuzne
26
floem co vede
vede ze zelenych casti rostlin do korene, ktere vyrobi pri fotosynteze nebo uklada, hromadi se v zasobnich organech - koren- mrkev, cibule- tulipany, narcis
26
typy vodiveho a zpevnovaciho pletiva
floem, xylem
27
xylem co vede
vede z korenu vodu do badzemnich casti rostlin tam se odparuje pomoci pruduchhu
28
floem
lukova cast
29
xylem
drevni cast;
30
cevy ve floemu
= vodive elementy floemu, sitkovice
31
cevy v xylemu
cevice
32
druhy usporadani cevnich svazku
kolateralni, bikolateralni, koncentricke, radialni
33
kolateralni
bocne
34
bikolateralni
dvoubocne
35
koncentricke
soustredne
36
radialni
paprscite
37
zesileni cev
kruhovite, sroubovite, schodovite
38
trvala zakladni pletiva
maji specificke funkce, vyplnuji prostory mezi krycimi a vodnimi pletivy
39
typy trvalich krscich pletiv
asimilacni, zasobmi, vodni, aerenchym, vymesovaci, hydatody
40
asimilacni pletiva
podileji se na fotosynteze tedy vyrobe organickych latek, v listech
41
zasobni pletiva
slouzi k ukladani ruznych latek, napriklad v koreench, hlizach, semenech, skrob
42
vodni pletiva
k ukladani vody, casto u rostlin v suchem prostredi, kaktusy, baobaby
43
aerenchym plativa
u rostlin ketre rostou ve vode nebo vlhkym podminkach, = vzdusne pletivo
44
vemesovaci pletivo
= sekrecni, podileji se na vylucovani latek napriklad silic, pryskyrice nebo jine, ochrana pred zvirat ktere ji pozivaji
45
hydatody
vylucuji ve forme kapek = gutace, na okrajich listu a obsahuji kanalky, hydatody pomahaji regulovat vodni bilanci rostlin
46
inděj u hydatod
ochranny obal ktery kryje vylucovaci otvory
47
deliva akivita
trvala pleti va nebo meristemy
48
trvala pletiva
ztraceji schopnost deleni
49
meristemy
neztraceji schopnost deleni
50
delive pletiv a
=meristemy,=meristematicke bunky
51
typy meristemu
puvodni meristem, prvotni = primarn,i, druhotny = sekundarnri, utajen=latentni,
52
puvodni meristem
= protomeristem, vzrostny vrchol stonku a korene , rustove zony listu, zarodky
53
prvotni meristem
=primatrni, vznika dlenim bunek iniciály, vzniks z prootomeristemu, dcerine bunky postupne ztraceji delivou schopnist a diferencuji se v bunky trvalych pletiv
54
iniciály
ve vrcholových catsech stonku ( konec vetve, okraje stonku, spiska korene) - bunky ketre se neustale deli a tim zpusobuji rust koncovych casti, vytvari primarni meristem
55
druhorny
=sekundarni, vznika obnovenim delive funkce trvaleho pletiva, př. felogen a kambium, prestali se dleit pote delivou schopnost obnovilyu
56
tajený
=latentní, bunky jsou mezi bunkami trvalych pletiv achovavaji se delivou schopnost, napriklad pericykl, perikambium
57
kambium
vytvari letokruhy, oddeluje drevni cast do stredu a lykovou ven , diky nemu tloustne stonek soucasti zakladnich pletiv i cevnich svazku
58
felogen
nachazi se pod krycim pletivem, zaplnuje trhliny ve stonku, vytvrai smerem fo stredu zelenou kuru ven korkove pletivo
59
korkove pletivo
popropustne por vodu a vzduch, lenticley - diry
60
lenticely
=dirky, umoznuji komunikaci stonku s vnejsim okolim
61
borka
odloupla kura stromu
62
korkovy dub
silne korkove pletivo, vyuziti : korkove zatky, izolantc
63
o vede asimilacni proud a jakou catsi cevniho svazku
organicke latky floem
64
letokruhy
vznikaji cinnosti kambia, vypovidaji o stari rostliny, vytvari se u drevin
65
co vymesuje latex
trbicove utvary - mlecnice vymesuji latex
66
jakou casti cevniho svazku je vedem transpiracni proud
= voda a mineralni latky, korenem, stonekem, xylem
