Plant Reproduction Quiz

Anatomy and Reproduction of Flowers

• Flowers contain both male (stamen) and female (pistil) reproductive organs.
• The stamen consists of the anther and filament and produces pollen.
• The pistil is made up of the ovary, style, and stigma, and receives the pollen.
• A flower with both male and female reproductive organs is called hermaphrodite or bisexual.
• Pollination is the transfer of pollen from the stamen to the stigma.
• Auto-pollination occurs when pollination happens within the same flower.
• Cross-pollination occurs when pollination happens between flowers of the same species.
• Pollen grains deposited on the stigma germinate and emit a pollination tube carrying the male gamete.
• The pollination tube penetrates the ovary and the male gamete fertilizes the female gamete of the ovule.
• Fertilization results in the formation of the egg cell, leading to sexual reproduction through the fusion of male and female gametes.
• After fertilization, the ovary increases in size and becomes a fruit containing seeds, while other flower parts fall away.
• The seed obtained from fertilization contains the plant embryo with stored food reserves in the cotyledons, which are used to nourish the embryo. The plant embryo then develops into a young green plant.
