Document Summary

Life history: major life history characteristics include: Number and size of offspring: variations in these characteristics reflect different allocations of an individual"s resources (i. e. , time, effort, and energy expenditure) to competing life functions. Phytoplankton: most phytoplankton reproduce asexually, by cell division. One frustule goes to each of the daughter cells. Macroalgae: complex reproduction with many possible life histories, alternations of generations (1n, 2n), production of sporophytes, etc, many have asexual (vegetative) reproduction. Thallus fragments can grow into a new individual: sexual reproduction involves production of gametes (eggs, sperm(1n)) Importance of seasonal timing by plants in temperate enviros. Seasonal phenology for growth, pollination, and reproduction. Optimum time for reproduction (seeds: ephemeral plants. Appear before leaves shade the forest floor. Trees that flower early and grow later. Trees that grow early and flower later. Fruiting can be variable also: annual and perennial strategies in terrestrial vascular plants. Trees and like plants (woody plants: annual plants.
