How are pollen and ova different to each other cells in a plant?

Pollen is not a cell it is actually the gametophyte of the plant. It contains 3 nuclei : 2 sperm nuclei and 1 tube nucleus. The pollen has to find its way into the ovary of the pistil. The tube nucleus will form a pollen tube through the pistil into the ovule. Once the connection is made the 2 sperm nuclei will enter and fertilize the egg and endosperm. The egg is the ova and is formed inside the ovule which is inside the ovary (fruit).

pollen=sperm=male



ova=egg=female
Reply:Fertilization in humans happens when sperm (male) and egg (female) meet. In plants, the sperm is the pollen and the ova is the egg.
Reply:Pollen grains are considered to be the first cells of male gametophyte.These pollen grains are the microspores which are formed by the meiosis of the pollen mother cell.These pollen grains contain two male gametes.One gamete fertilizes the egg cell and the other gamete fertilizes the secondary nucleus to form the endosperms (generally in angiosperms)





Ova are the egg cells which on fusing with the male gamete form the zygote.
Reply:Pollen contains the male gamete which is the sperm whereas ovum(plural is ova) is the female gamete. Both sperm and ovum contain half the number of chromosomes that is they are haploid. Other cells of the plant such as photosynthetic cells and epidermal cells are diploid that is they have complete set of chromosomes.
