Nectar is a sugar-rich liquid produced by plants in glands called nectaries, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide antiherbivore protection.
What role do petals and sepals have in reproduction? Petals are big and brightly coloured to attract insects for pollination. Sepals are green, so they can conduct photosynthesis. Thay make food for the flower. Flowers are the r â¦ eproductive part of a plant because they produce fruit which contains seeds. The sepals also play a major role in protecting the flower during its bud stage.
