Fungi are unique and important organisms which belong to their own kingdom, completely separate from plants and animals.Fungi are not plants – they have no leaves or flowers, no cellulose or chlorophyll. Instead they comprise microscopic, thread-like structures termed ‘hyphae’, through which they absorb nutrients. They are a hugely diverse group of great economic importance, yet they remain vastly under-studied compared to plants. It is estimated that there may be as many as 1.5 million species of fungi in the world – more than six times the number of flowering plants. Yet only about 100,000 species have so far been described.
Virus adalah mikroorganisma terkecil…jauh kebih halus dari bakteria! Virus tidak diklasifikasi sebagai benda hidup, haiwan atau tumbuhan!
