Fruit & Seed Dispersal
Giant Kelp also a Protist!
Gymnosperm & Angiosperm Seeds
Flowering Plants: Monocot & Dicot Seeds
Fruit of a Peanut Plant Forms in the ground Fertilization of an egg & pollen makes a seed Fruit is the ovary around the seed
Plants: Nonvascular & Vascular
Honey Possum & Bee Pollinators
Fruit & Seed Dispersal
Pollination versus Fertilization Pollination: Mechanical Transfer of pollen: Fertilization: Joining Of pollen(sperm) with The egg in ovary
Cone Bearing Plants Gymnosperms Cones naked seeds No ovaries Pollen
Ovaries surround the seeds Seed = Fertilized egg Ovary becomes the fruit
The stem of a plant provides pathways for the distribution of water and nutrients between the roots, leaves, and other parts of the plant. The herbaceous stem of the dandelion (top, center) lacks lignin, the stiffening material in rigid, supportive woody stems. For this reason, herbaceous plants are generally limited in their physical size. Spurges and cacti (bottom, left), their leaves reduced to needles to prevent evaporation in a dry climate, consist entirely of stem material. Tubers, such as potatoes (top, right), are swollen, food-storing, underground stems that nourish growing buds. The stems of some plants are adapted for protection, as in the hawthorn (bottom, right). Others actively compete for sunlight, using touch-sensitive, curling tendrils (top, left) or other structures to climb upwards.

When scientists compare present-day plants and present-day green algae, they find the following common characteristics: 21.1 Plant Evolution and Adaptations.
Reproduction in living organisms (other organisms … not you) (that topic is covered in health class)
Plant Reproduction. Two Forms of Plant Reproduction Sexual Reproduction Asexual Reproduction Meiosis + Fertilization Mitosis + Vegetative Propagation.
Asexual Reproduction Asexual reproduction involves only one parent who passes on the genetic information to their offspring. This sharing of genetic information.
