Iga organism koosneb rakkudest Rakk on v ikseim ksus, millel on k ik elu tunnused. Rakud on n htavad mikroskoobiga
Mis on taime- ja loomarakkudel hist? mbritseb ja kaitseb rakke Laseb valikuliselt aineid raku sisse ja rakust v lja RAKUMEMBRAAN
Mis on taime- ja loomarakkudel hist? RAKUPLASMA Seob raku htseks tervikuks ja tagab selle osade koost Organellides toimuvad mitmesugused ainevahetusreaktsioonid: s ntees ja l hustamine Rakuplasmasse kogunevad mitmesugused raku elutegevusel tekkinud j kained
Mis on taime- ja loomarakkudel hist? Juhib raku kogu elutegevust, sealhulgas raku jagunemist S ilitab ja annab edasi p rilikku informatsiooni RAKUTUUM
Mis on taime- ja loomarakkudel hist? MITOKONDRID Varustavad rakku energiaga
Mille poolest erineb taimerakk loomarakust? RAKUKEST Kaitseb ja toestab rakku ning annab sellele kuju Avaldab j ikuse t ttu vee sissetungile vastum ju ja takistab nii vee liigset sissetungi rakku Laseb vabalt l bi pooride vett ja paljusid selles lahustunud aineid rakku ja rakust v lja Pooride kaudu on naaberrakkude rakuplasmad henduses
Mille poolest erineb taimerakk loomarakust? VAKUOOL Sisaldavad vett ja varuaineid Koguvad j kaineid ja lagundavad neid Reguleerivad raku siser hku ning aitavad sellega s ilitada raku kuju.
Mille poolest erineb taimerakk loomarakust? KLOROPLASTID Neis toimub fotos ntees
Rakus on veel plastiide, mis vivad ksteiseks le minna Kromoplastid Leukoplastid Annavad lehtedele v i viljadele kollaka-oran ika v rvuse Paiknevad tavaliselt taimede maa-alustes osades, on v rvitud ja sisaldavad varuaineid (t rklist)
Kuidas ained rakku liiguvad? Vee liikumist l bi pooll bilaskva membraani v iksema kontsentratsiooniga lahusest suurema kontsentrat- siooniga lahusesse nimetatakse OSMOOSIKS Vaata siit kuidas osmoos toimub
Kuidas taimerakk oma kuju silitab Rakku tungiv vesi paisutab rakku Selline prink rakk on surutud tihedalt vastu k rvalrakke ja niiviisi ksteist toestades hoiavad need taime p sti Kui v ljaspool on mineraalainete kontsentratsioon suurem, hakkab vesi rakust v lja liikuma ja taim n rtsib
