Plant Reproduction and Flower Parts

The male sexual organ of a plant is called stamen.

The carpel is the top part of the flower responsible for receiving pollen.

Spores are produced by meiosis during the sporophyte stage of plant life cycle.

The zygote is formed by the fusion of a male gamete and a female gamete.

The flower part that attracts insect pollinators by color and fragrance is called the sepal.

Self-pollination guarantees genetic variation in plants.

Insect-pollinated flowers typically have brightly colored petals and strong scent to attract pollinators.

The process of double fertilization in plants involves the fusion of two male gametes with the egg and the polar nuclei.

Wind-pollinated flowers generally have showy colors and produce nectar to attract insects.

Pollination is essential for seed and fruit formation in plants but not for genetic variation.

Dormancy in plants is a period when growth is accelerated to ensure survival during winter.

Asexual reproduction in plants involves gametes and fertilization.

Root tubers are underground roots that actively grow and produce new plants during winter.

Artificial vegetative propagation involves growing a new plant from a portion of the parent plant.

Tropism occurs when plant growth is away from an external stimulus, like thigmotropism.
