Tips for you:

1. All living organisms are made of cells.

2. A cell is a basic unit of life.

3. Plant cell differ from animal cell

4. Each cell component has specific function

Hai manusia, apakah yang telah memperdayakan kamu (berbuat durhaka)

terhadap Tuhanmu Yang Maha Pemurah. Yang telah menciptakan kamu

lalu menyempurnakan kejadianmu dan menjadikan (susunan tubuh)mu

seimbang, dalam bentuk apa saja yang Dia kehendaki, Dia menyusun

tubuhmu.

[Al Infithaar, 82:6-8]

Dan pada kejadian diri kamu sendiri, serta (pada kejadian) segala binatang

yang dibiakkanNya, terdapat juga tanda-tanda (yang membuktikan kekuasaan

Allah) bagi orang-orang yang meyakininya.
