(c) In bryophytes each sperm usually consists of minute, slender, spirally curved body furnished with two long, terminal whiplash type flagella. The sperms are liberated from antheridia, swim in a film of water and attracted towards the archegonium. They enter into the archegonia and fertilise the egg and form zygote. Zygotes do not undergoes reduction division immediately. They produce a multicellular body called a sporophyte |
