Flower Structure and Function

Petals

• Often brightly colored, the colors, number, and shapes of the petals attract insects and other pollinators to the flower.

• Petals are primarily responsible for photosynthesis in plants.

• Petals are the reproductive organs of the flower.

• Petals are usually green and help in the growth of the plant.

Plant reproduction

• The process by which plants make new plants, typically through flowers or cones and seeds.

• The method by which plants absorb nutrients from the soil.

• The way plants convert sunlight into energy through photosynthesis.

• The technique plants use to attract pollinators for reproduction.

• Structure C

Stem

• A structure that holds up leaves to capture more sunlight.

• A part of the plant that absorbs water and nutrients from the soil.

• The reproductive part of a plant that produces seeds.

• A protective outer layer of a plant that prevents water loss.

Pistil

• Male part of the flower, consisting of an anther and filament.

• Female part of the flower. Consists of a stigma, style, and ovary.

• Part of the flower that attracts pollinators with its color.

• The green part of the flower that supports the petals.

Fertilization

• The process of planting seeds in soil.

• The action or process of fertilizing a plant, involving the fusion of male and female gametes to form a zygote.

• The method of watering plants to promote growth.

• The process of harvesting crops after they have matured.

Germination

• The process of seeds or spores sprouting and beginning to grow.

• The process of photosynthesis in plants.

• The process of pollination in flowering plants.

• The process of seed dispersal by wind or animals.

Filament

• Stalk like structure that supports the anthers.

• Thin thread that connects the roots to the leaves.

• Part of the flower that attracts pollinators.

• Structure that produces pollen grains.

Female flower parts

• Pistil = stigma, style, ovary & ovule.

• Stamen = anther, filament

• Petal = corolla, sepal

• Receptacle = ovule, style, stigma
