b. Gametophyte and sporophyte of Funaria. External Structure of Marchantia: The gametophyte of Marchantia is a dichotomously branched, prostrate, dorsiventral thallus (Fig. The sequential stages of pollen devel- opment are shown in Figure 1. What is a pollen tube? Pollen grain (microspore) transferred to the stigma of the flower develops into male gametophyte. 6.What is a pollen tube? 1 spermatangium: Carposporangium of a red alga: A carpospore and B carposporangium. In a plant’s male reproductive organs, development of pollen takes place in a structure known as the microsporangium (Figure \(\PageIndex{5}\)). Ask questions, doubts, problems and we will help you. Male gametophyte .

The male gametophyte develops reproductive organs called antheridia (produce sperm) and the female gametophyte develops archegonia (produce eggs). The female gametophyte forms carpogonia in which the egg cell can be found.

Similar to the male gametophyte, the female gametophyte normally is fully dependent on the surrounding sporophytic tissue for nutrients and the two organisms cannot be separated. Diploid sporephyte generation MEIOSIS 0 FERTILIZATION 1. Question 2. The pollen tube grows through the style towards the ovule due to some chemical stimulus inside the ovary. Label any four parts. Also draw a labelled diagram of embryo sac to explain the phenomena. The microsporangia, which are usually bi-lobed, are pollen sacs in which the microspores develop into pollen grains. The splash cup at the top of the gametophyte holds the male gametangia, antheridia. Obtain a prepared slide of a Mnium male gametophyte (antheridial head).

Non-vascular plants must live in moist habitats and rely on water to bring the male and female gametes together. (b) Draw a diagram of a mature human male gamete. Sproropollenin is very hard substance as it can withstand high temperature, strong acids and alkali. The pollen tube comes from the tube cell from the male gametophyte. The sperm cells which are foreseen of flagella can reach the female gametophyte by means of a drop of (rain)water. Question: Draw A Diagram Of The Lifecycle Of A Seedless Plant You Do Not Need To Draw Pictures Of The Stages. 13.1; Ma, 2005, Wilson and Zhang, 2009). Spermatangia producing spermatia develop on fertile "side shoots" (not real shoots) of the male gametophyte. Question 6. At stage 1, an anther primodium is formed from the floral meristem.
