- The process of pollination (including structures or organs involved)

- The process of fertilization (including structures or organs involved)

- The ovule (and its components)

Explanation / Answer

Flower - Sterile Parts1. Peduncle = flower stalk• receptacle (swollen tip of peduncle; flower parts attached here) 2. Sepals• sepals collectively known as the calyx 3. Petals• petals collectively known as the corolla

Flower - Fertile Parts ,Stamens – male reproductive organs, collectively called androecium a. Filament b. Anther • pollen grains develop here ,Pistil (Carpel) = female reproductive organ, collectively called gynoecium

1) Stigma2) Style3) Ovary contains ovules a) Ovules mature into seeds b) Ovary matures into fruit

Flower parts•Four basic parts are:

–Pistils (Gynoecium)

–Stamens (Androecium)

–Petals (Corolla)

–Sepals (Calyx)

•Each of these sets of parts may form a whorl or a series of spirals, with sepals outermost, pistils innermost
