No ke aha la i lau uliuli a pau? No ke aha la e pono ai ia?

Ka 'ole o ka mea kanu

Ka mea hiki e unicellular paha multicellular. Ka hope, ua mahele ia i pauku e like me uliuli, eleele a me ka ʻulaʻula līoho, spore, gymnosperms a me angiosperms. ka līoho kino ke komo ana o ka hookahi halepaahao, a no ka mea he nui, akā, ma kā lākou 'ole loaʻa nāʻaʻohe kino, paa kino - kapaia ka thallus. Ma spore, gymnosperms a me angiosperms (flowering kanu) malama i ke alo o differentiated nā'aʻaʻa a me nā loko. Recent maheleia i vegetative a me ka generative. Ka mua kēia e pakele ai (kumu a me na lau) a me ke kumu. He nui nā kanaka kahaha, "'ōmaʻomaʻo lau No ke aha la," No ke aha la keia ano? Nō hoʻi, he nui na keiki ninau i ka nīnau: "No ke aha la i ka uliuli lau?" A o keia 'atikala mākou e hoʻomaka i keia kumuhana.

No ke aha la i lau uliuli a pau?

Kēia ke kala mea ku pono i ke alo o ke chlorophyll. Ma ka Akuma ka o ka pigment ua lilo, a me ka uliuli pepa ua hoohuliia i loko oʻulaʻula,ʻalani a melemele. No ke aha la oe i pono ai i kēia mea? He wale nui no ka mea kanu. Me ka mea hiki ole ke hoomau aku i ke kaʻina hana o ka kāʻamaʻai ana i ka mahuaola i lawe. Ke aloha Nine Inch mea kanu i ana loaa wale ma keia kaʻina. Naʻe, kekahi? Ueo e noho ana ma ka lalo papa o ka rainforest, maiʻaʻole e lawa ka malamalama no ka kāʻamaʻai piha, pela io, e imi i ka poe liilii, nā mea kolo, pela compensating no ka nele o ke aloha i huiʻia.

Pokole e pili ana i ka 'ole o ka mea kanu aeea

Ua ninoieo o ka wai kokoʻili lahilahi, o ka halepaahao paia o ka kelulose, ke cytoplasm, iloko ona i kakauia organelles a me ka nucleus i ka DNA. Ke cytoplasm he mau organelles: ka mitochondria, ribosomes, endoplasmic reticulum, vacuole (i loko o ka hīnaʻi manu kahiko - hoʻokahi nui, ma ka opiopio - he mau wahi ia), ka Golgi eiiieaena, a me plastids (chloroplasts, leucoplasts, chromoplasts). Kēlā me kēia no ia hanaʻia kona kuleana pili i. Mitochondria paka ikehu, ribosomes synthesize nā polokina endoplasmic reticulum (reticulum) paha ke lipid vacuoles loaa hua'ōlelo i makemake 'ona i kēpau ia mawaho o ka paa halepaahao pa hiki ole i loko o chloroplasts ae kāʻamaʻai kaʻina, chromoplasts pihaʻi me pigments, leucoplasts waiho waho no? Mahuaola ( holo nōhie, keia pia).

Pehea ka kāʻamaʻai?

Kēia kaʻina ua lawe mai i loko o ka chloroplasts, a i aia i loko o ka cytoplasm. Mau organelles i odnomembrannymi i loko o kā lākou 'ole nā thylakoids - a lahilahi ohi ia i loko o ka maka - ke noae. Ua mea i loko o ia, a pihaʻi me chlorophyll - i ka ke kumu'ōmaʻomaʻo lau. Eia kekahi, chloroplasts pihaʻi me ribosomes, komo i loko o ka hoʻomanaʻo o nā polokina, pia granule, e like me hoʻopoepoe DNA lātoma, ma i hōʻike ua palapala ma luna o ka waiwai i mea e e synthesized i loko o ka halepaahao.
