Meiosis occurs within sporangia, located on the underside of the sporophyte leaf. After the spores are released they germinate, divide by mitosis and grow into simple heartshaped gametophytes.
Does meiosis occur in ferns?
In ferns, the multicellular sporophyte is what is commonly recognized as a fern plant. On the underside of the fronds are sporangia. Within the sporangia are spore producing cells called sporogenous cells. These cells undergo meiosis to form haploid spores.
At what time meiosis takes place in fern?
Thus the spores produced are haploid in nature and germinate to produce a prothallus that represents the gametophytic generation. Antheridium and archegonium are borne on this prothallus. Thus meiosis takes place at the stage of spore formation.
What is meiosis and where does it occur?
Meiosis is the process of cells splitting into four haploid cells, thus reducing the chromosome number by half in each cell. … Meiosis occurs in the sex cells, so the sperm and egg cells in the human body, to create even more of themselves.
Does meiosis occur in plants?
In plants, meiosis is initiated in sporogenous cells that are differentiated in ovules and anthers (Bhatt et al., 2001). In each ovule, only a single megaspore mother cell (MMC) surrounded by the somatic nucellar cells is differentiated and then undergoes meiosis (Figure 1).
Where do ferns grow best?
Woodland ferns do best in high or dappled shade. The open shade of mature trees or the north side of the house or a wall, open to the sky, provide nearly ideal light conditions. Most woodland ferns will adapt to relatively low light levels, but no ferns thrive in deep shade.
