Parts of a Flower and Pollination

Parts of a Flower

• Petals: Colored parts of a flower, often noticeable.
• Stamen: The male part of the flower.
  • Anther: Produces and holds pollen.
  • Filament: A stalk that supports the anther.
• Pistil: The female part of the flower.
  • Stigma: Sticky surface at the top of the pistil, traps and holds pollen.
  • Style: Tube-like structure that holds up the stigma.
  • Ovary: Enlarged basal portion of the pistil, containing ovules.
  • Ovule: Contains the female reproductive cells.
• Sepal: Outer, often green and leaf-like parts of the flower that enclose developing buds.
• Receptacle: The part of the flower stalk where flower parts attach.

Flower Structure

• Perfect Flower: Has both pistil and stamen.
• Imperfect Flower: Has either a pistil or a stamen.

Pollination

• Pollination: Transferring pollen grains from the anther to the stigma.

Self-Pollination

• Self-Pollination: When pollen from the anther is deposited on the stigma of the same flower or another flower on the same plant.

Cross-Pollination

• Cross-Pollination: Transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same kind of plant.

Fertilization

• Fertilization: Pollen from a flower meets with the ovule in the female part (pistil) and forms seeds.

Parts of a Fruit

• Pericarp: The fruit wall.
  • Exocarp: Outer layer of the fruit.
  • Mesocarp: Middle layer of the fruit.
  • Endocarp: Inner layer of the fruit.
• Seed: Develops from the ovule after fertilization.

Life Cycle of a Plant

• Seed: Starts the cycle.
• Sprout: Growing from seed.
• Seedling: Growing plant from sprout.
• Plant: Fully developed plant.

Germination

• Germination: Process where a seed grows into a new plant.

Needs of Plants

• Light
• Gases from the air
• Room to grow
• Nutrients
• Water
• Correct temperature

Plant Classification

• Classified by Structure
• Classified by Habitat

Plant Types

• Trees: Tall plants with big woody stems.
• Shrubs: Shorter than trees with woody stems.
• Vines: Plants with thin long stems that climb up walls or trees, sometimes crawling on the ground.
• Herbs: Fleshy stems that can be easily cut, some can be eaten or used as medicine.
• Grass: Plants with blade-like leaves, low, green, and non-woody plants.
• Xerophytes: Plants that live on land.
• Hydrophytes: Plants that live on water.
• Epiphytes: Plants that grow on the surface of another plant.
