Ovule: The ovule is located in the ovary of a flower. The three parts of an ovule are the integument, the nucellus and the female gametophyte. The female gametophyte contains the egg cell, which is fertilized by the sperm cells from the pollen grains. ...

This is the process known as pollination, and it represents the most critical moment in the life of a flower. Although the outcome of this process is strongly conditioned by change,. Nevertheless, evolution has effectively reduced the accidental element by fostering certain mechanisms that guarantee...
aIn addition, studies indicate that a similar mechanism is involved in the development of inner nonflattened organs, such as the stamen, carpel, and ovule (Eshed et al., 1999, 2001; Kelley et al., 2009). For example, anthers are radialized in kan, phb-1d, and filamentous flower (fil...
Apomixis in flowering plants is defined asthe asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization, leading to embryo development. What is apomictic embryo? Apomixis:Embryo Sacs and Embryos Formed without Meiosis or Fertilization in ...
Open up a flower and you will find many distinct parts that all contribute to the production of seeds. The most obvious parts of a flower are the petals, which have two jobs. The first duty is to protect the precious seeds, and the second job is to attract pollinators. Pollinators, ...
