jindgi ke silsile

Cell (कोशिका) ek basic structural aur functional unit hai jo sabhi jivashon mein paya jata hai. Har jivashar, chhota ya bada, ek ya multiple cells se bana hota hai. Ye cells jivashar ke sabhi karya aur processon ko samarthan karte hain. Ek cell mein kai prakar ke organelles hote hain jo alag-alag karyon ke liye zimmedar hote hain. Koshika ek microscopically chhota unit hoti hai jisme genetic material (jaise DNA) bhi hota hai jo jivashar ke vikas aur karyaon ka niyantran karta hai. In general, cell ko jivashar ki building block ya structural aur functional unit mana jata hai. Ye plants, animals, fungi, protists, bacteria, aur archea jaise vibhinn prakar ke jivashar mein paya jata hai.

Atomic structure refers to the organization and arrangement of subatomic particles within an atom. Atoms are the basic builticles: protons, ny charged particles found in the nucleus of an atom. The number of protons in an atom is known as its atomic number (Z), Neutrons: Neutrally charged particles found in the nucleus along with protons. Together, protons and neutrons form the nucleus of an atom. Electrons: Negatively charged particles that orbit the nucleus in electron shells or energy levels. The number of electrons in an atom is usually equal to the number of protons, creating an electrically neutral atom. Electrons are involved in chemica
