Structure of flower

Even though there are many different flowers, most of them have the same parts.

• Stamen: male reproductive organ
• Pollen: male sex cells

• Carpel: female reproductive organ

(stigma, style, ovary)

• egg cell: female sex cell

Pollination: transferring pollen from stamen to stigma.

Pollen grains do then have to get onto the stigma of the flower of the same plant species!

Insect-pollinated flowers

• Large and colorful petals, 
• Nectar, 
• Small amount of pollen

Wind-pollinated flowers

• Flowers small and not colorful, 
• Produce large amount of pollen, 
• Anthers often hang out of flower, 
• Stigma's large and feathery.

       Biotic: living things            Abiotic: non-living things
