Male part of flower Consists of anther and a filament
- Filament
- stalk → that holds the anther in suitable position to disperse the pollen
- Anther
- consists of 2 lobes each containing 2 pollen secs
- pollen gains are found in these sacs
- produces pollen grains.
- when anther matures → it splits open to release pollen grains
- anther contains vascular bundle: Phloem → translocate sucrose and amino acids to developing anther. Xylem → transport water and mineral salts.
- Pollen grains
- CONTAIN male gamete.
- male games → produced by meiosis → are haploid
- have 1/2 number of chromosomes as a normal cell
- if normal cell of plant has 20 chromosomes, then gamete will have 10 chromosomes
Pollen = plant sperm
- thus hay fever is an STD
