TOHUMUN YOLCULU\u011eU<\/strong><\/p>\n

\u0097\u00a0 Tohumlar yeni bir bitkiyi olu\u015fturabilecek t\u00fcm \u00f6zelliklere sahiptir.<\/p>\n

\u0097\u00a0 Tohum say\u0131s\u0131 baz\u0131 bitkilerde az, baz\u0131 bitkilerde ise fazlad\u0131r. \u00d6rne\u011fin, \u00e7ilek, biber gibi meyvelerin tohumlar\u0131 fazla; kiraz, kay\u0131s\u0131, erik gibi meyvelerin tohumlar\u0131 tektir.<\/p>\n

\u0097\u00a0 Tohumlar yeterince b\u00fcy\u00fcy\u00fcp olgunla\u015ft\u0131ktan sonra de\u011fi\u015fik yollarla etrafa yay\u0131labilir.<\/p>\n

\u0097\u00a0 Baz\u0131 bitkilerin tohumlar\u0131, patlayan tohum zarflar\u0131 i\u00e7indedir. Tohumlar, bu \u015fekilde uzaklara f\u0131rlat\u0131labilir.<\/p>\n

\u0097\u00a0 Baz\u0131 hafif tohumlar\u0131n yay\u0131lmas\u0131 ise r\u00fczg\u00e2rla olur.<\/p>\n

\u0097\u00a0 T\u00fcm bunlar\u0131n yan\u0131nda hayvanlar da tohumlar\u0131n ta\u015f\u0131nmas\u0131nda etkilidir. Bir hayvan, meyveyi yedi\u011finde meyvenin i\u00e7indeki tohum genellikle sindirilmez ve d\u0131\u015fk\u0131 yoluyla topra\u011fa at\u0131l\u0131r. B\u00f6ylece tohum uzaklara ta\u015f\u0131nm\u0131\u015f olur.<\/p>\n

\u0097\u00a0 Yedi\u011fimiz besinlerin b\u00fcy\u00fck k\u0131sm\u0131n\u0131 meyveler ve tohumlar olu\u015fturur. \u00c7ilek, elma, domates gibi besinlerin\u00a0hem tohum hem de meyvelerini yeriz. Kestane, ceviz gibi a\u011fa\u00e7lar\u0131n yedi\u011fimiz k\u0131s\u0131mlar\u0131 ise\u00a0sadece tohumlar\u0131d\u0131r.\u00a0Ay\u00e7i\u00e7e\u011finin tohumu olan ay \u00e7ekirde\u011fi ise yedi\u011fimiz tohumlar aras\u0131ndad\u0131r.<\/p>\n

Yeni teknolojiler kullan\u0131larak \u00e7e\u015fitli i\u015flemlerden ge\u00e7en pamuk; ya\u011f,\u00a0 \u00f6rt\u00fc, dokuma ya da elbiselerimizin kuma\u015f\u0131 olarak kullan\u0131m\u0131nda yer al\u0131r.<\/p>\n

\u0097\u00a0 Do\u011fadaki bir tohum, uygun ko\u015fullar\u0131 bulabilirse \u00e7imlenerek b\u00fcy\u00fcmeye ba\u015flar. Bu, bir bitkinin ya\u015fam d\u00f6ng\u00fcs\u00fcd\u00fcr.<\/p>\n

\u0097\u00a0 Tohumlar\u0131n \u00e7o\u011fu, \u00e7imlenme i\u00e7in uygun ko\u015fullar bulana kadar uyku halindedir.<\/p>\n

\u0097\u00a0 Tohumun \u00e7imlenmesi i\u00e7in gerekli \u015fartlar:<\/p>\n

Oksijen\u2019dir.<\/p>\n

\u0097\u00a0 \u00c7imlenme i\u00e7in nem, su, \u0131s\u0131 ve oksijen yeterlidir.<\/p>\n

\u0097\u00a0 Tohum, \u00e7imlenme s\u0131ras\u0131nda solunum yapar ve i\u00e7erisinde bulunan besini kullan\u0131r.<\/p>\n

\u0097\u00a0 Tohum oksijenli ortamda, uygun nem ve \u0131s\u0131y\u0131 buldu\u011funda \u00e7imlenir.<\/p>\n

\u0097\u00a0 Yeni bitkiyi tohum i\u00e7indeki embriyo olu\u015fturur. Embriyo, toprak \u00fczerine \u00e7\u0131k\u0131p filizlerini olu\u015fturdu\u011fu zaman fotosentez yaparak kendi besinini \u00fcretmeye ba\u015flar.<\/p>\n

\u0097\u00a0 \u00c7imlenen tohum filiz ve k\u00f6k olu\u015fturur.<\/p>\n

\u0097\u00a0 Toprak, bitkiler i\u00e7in hem su hem de ihtiya\u00e7 duydu\u011fu madensel tuzlar\u0131 alabilece\u011fi bir kaynakt\u0131r.<\/p>\n

\u0097\u00a0 D\u00fczenli sulama bitkinin b\u00fcy\u00fcmesi i\u00e7in \u00f6nemlidir. Bitkiyi az sulamak kurumas\u0131na neden olurken \u00e7ok fazla sulamak da \u00e7\u00fcr\u00fcmesine neden olabilir.<\/p>\n

\u0097\u00a0 Gen\u00e7 bir bitki b\u00fcy\u00fcrken boyu uzar, yaprak say\u0131s\u0131 artar, k\u00f6klerine yeni k\u00f6kler eklenir.<\/p>\n
