Difference between Apomixis and Ovule

Apomixis vs. Ovule

In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization. In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells.

Asexual reproduction

Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes.

Asteraceae

Asteraceae or Compositae (commonly referred to as the aster, daisy, composite,Great Basin Wildflowers, Laird R. Blackwell, 2006, p. 275 or sunflower family) is a very large and widespread family of flowering plants (Angiospermae).

Megaspore mother cell

A megaspore mother cell, or megasporocyte, is a diploid cell in plants in which meiosis will occur, resulting in the production of four haploid megaspores.

Meiosis

Meiosis (from Greek μείωσις, meiosis, which means lessening) is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.

Nucellar embryony

Nucellar embryony (notated Nu+) is a form of seed reproduction that occurs in certain plant species, including many citrus varieties.

Ploidy

Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.
