Chapter4 Plant Reproduction

Self-pollination

Pollen grains transferred to the stigma of the same flower

Cross-pollination

Pollen grains transferred to the stigma of another flower on a different plant of the same species

Pollinating Agents

Animals and Insects

Characteristics of animal/insect-pollinated flowers

Big, colorful petals, Nectar, pleasant smell, Rough, sticky pollen grains

Examples of animal/insect-pollinated flowers

durian, rambutan, hibiscus

Wind pollination

Light pollen grains carried by wind to another flower's stigma

Characteristics of wind-pollinated flowers

White or pale petals, Long, furry stigma, Small, smooth, light pollen grains

Examples of wind-pollinated flowers

corn, grass, paddy

Advantages of Cross-Pollination

Resistant to pests and diseases, Healthier, adaptable plants, New plant varieties, quality seeds

Hybrid Plant

Result of cross-pollination between different parent plants

Palm Oil

Result of cross-pollination between Pisifera and Dura plants, producing Tenera with more fruits and thinner shell

Examples of hybrid plants

Papaya varieties Subang 6 and Sunrise Solo, Eksotika with sweeter, bigger fruits
