įsielektrinančio teigiamai – sumažėja, neigiamai –

Kūnai gali įsielektrinti ne tik trinami vienas
į kitą, bet ir suliesti. Šis reiškinys turi praktinę
reikšmę. Daktiloskopijoje jis taikomas pirštų at-
spaudams aptikti. Liesdami pinigų kupiūrą, pirš-
tai palieka joje labai mažų teigiamai įelektrintų
baltymų dalelių. Šios pritraukia neigiamai įelek-
trintas aukso dulkeles, dengiančias kupiūros pa-
viršių. Taip iš aukso dulkelių susiformuoja pirštų
atspaudas. Kūnai gali įsielektrinti juos apšvie-
čiant arba šildant.
## Elektros krūvio tvermės dėsnis
Elektros krūvio tvermės dėsnis buvo nusta-
tytas bandymais. Bandymui reikalingi du elektro-
metrai. Prie pirmojo elektrometro
(1) pritvirtinkime metalinį diską, o ant jo už-
dėkime kitą tokį pat diską su izoliatoriaus ran-
kenėle. Tarp diskų įkiškime skiautelę audinio
(pvz., gelumbės). Viršutiniu disku keletą kartų
perbraukime per audinį ir palieskime antrojo
elektrometro (2) virbalą. Šio elektrometro rody-
klė pakrypsta apytiksliai tokiu pat kampu kaip
ir pirmojo. Tai rodo, kad tuo pačiu metu įsielek-
trina abu susiliečiantys kūnai: pirmasis diskas su
gelumbe ir antrasis diskas.
Laidininku sujunkime abiejų elektrometrų vir-
balus. Elektrometrų rodyklės su-
gržo į pradinę padėtį. Vadinasi, elektrometrų
virbalai išsielektrino, t. y. jų krūvis neutraliza-
vosi. Tai rodo, kad bendras abiejų diskų elek-
tros krūvis lygus nuliui. Šis ir panašūs bandy-
mai patvirtina, kad įsielektrinančiuose kūnuose
visuomet atsiranda vienodo modulio ir priešingų
ženklų elektros krūviai. Kūnams įsielektrinant,
krūviai persiskirsto, tačiau bendra jų suma ne-
kinta. Elektros krūvio tvermės dėsnis teigia, kad
visų sąveikaujančių uždarosios sistemos
kūnų elektros krūvių algebrinė suma yra
pastovi:
q₁ + q₂ + q₃ + ... + q<0xE2><0x82><0x99> = const. (1.2)
Gamtoje niekada neatsiranda ir neišnyksta be
pėdsako vieno ženklo krūvis. Kartu su neigia-
muoju krūviu –q visada yra sukuriamas to paties
modulio teigiamasis krūvis +q. Nei neigiamasis,
nei teigiamasis krūvis negali išnykti atskirai vie-
nas nuo kito. Jeigu jų moduliai lygūs, jie gali tik
kompensuoti vienas kitą.

# Augalų mityba
Kuo gyvūnai skiriasi nuo augalų? Galima nurodyti kelis skirtumus, tačiau svarbiausias – mityba. Gyvūnai ėda augalus arba kitus gyvūnus. Taip jie apsirūpina maisto medžiagomis, kurių reikia energijai gauti ir ląstelėms atnaujinti. Augalai nieko neėda, bet maisto medžiagų jiems irgi reikia. Kaip augalai apsirūpina jomis?
## Fotosintezė – cheminis virsmas
Augalai iš aplinkos ima paprastas molekules ir iš jų pasigamina sudėtingų. Tai vadinama sinteze (gr. *synthesis* – sudarymas). Šiam cheminiam virsmui būtina energija. Augalai jos gauna iš saulės, t. y. naudoja saulės šviesos energiją. Dėl to tikrasis šio proceso pavadinimas yra fotosintezė (gr. *phōtos* – šviesa + *synthesis*).
Fotosintezė vyksta žaliosiose augalų dalyse. Tu jau žinai, kad augalams žalią spalvą suteikia pigmentas chlorofilas. Jis susikaupęs chloroplãstuose, kurių turi augalinės ląstelės. Chlorofilas sugeria fotosintezei būtiną šviesos energiją.
Įsižiūrėk į fotosintezės schemą. Joje matyti, kad šviesos energija padeda anglies dioksidą ir vandenį paversti gliukoze bei deguonimi. Anglies dioksidą augalas ima iš oro, o vandenį siurbia iš dirvožemio. Vykstant fotosintezei susidaranti gliukozė – augalo maistas. Deguonis yra šalutinis fotosintezės produktas. Jį augalas išskiria į aplinką.
Fotosintezė – sudėtingas keliais etapais vykstantis cheminis virsmas. Jį galima užrašyti žodine lygtimi.
