Presentation Transcript

  1. Division: Coniferophyta • Evergreen & pine trees produce pollen in small male cones • Unfertilized eggs are kept in larger female cones • When the pollen is mature, it is released into the wind in the hopes that it will land on a female cone & fertilize the egg • The fertilized egg becomes a seed & is dropped to the ground when mature

  2. Because the seed is exposed to the elements as soon as the cone opens, it is called a ‘naked seed’ or gymnosperm

  3. Division: Ginkgophyta • Crossover plants that produces both cones and fruit

  4. Has distinctive fan-shaped leaves that all fall within a 24 hour period in the fall • Was thought to be extinct at one time so is now considered to be a ‘living fossil’ • Has been found to have health benefits mostly dealing with brain health

  5. Division: Magnoliophyta • These are the most advanced organisms in the plant kingdom • They produce flowers to attract pollinators to help ensure that their seed become fertile • They also have developed elaborate methods of protecting their seeds and dispersal of their seeds

  6. Flower Function • Function of a flower is to attract pollinators • This is done through scent, nectar and color

  7. Flower Structure • Flower parts include: • 1. Sepals: these protect the flower before it opens • 2. Petals: these are the colorful part of the flower & are designed to attract pollinators

  8. 3. Stamens: male reproductive parts • Made up of a filament & an anther which produces pollen • 4. Carpels: female reproductive parts • Made up of a stigma, style, pistil & ovary • Plants that produce flowers & protect it’s seeds are called: angiosperms

  9. Seeds • A seed is a plant embryo surrounded by a protective coat called a seed coat • Monocots have only one cotyledon that provide energy to the seedling until it can begin photosynthesis • Dicots have two cotyledons • The embryo is found between the cotyledons

  10. Plumule: is what will become the plant shoot • Radicle: is what will become the first root of the new plant • Hilum: is the scar from where the seed was attached to the ovary wall
