    Study Notes

    Plant Reproduction

    • Flowers are the reproductive shoots of angiosperms
    • Receptacle is where floral organs are attached
    • Reproductive organs are stamens and carpels
    • Sterile organs are sepals and petals
    • Sepals enclose and protect the floral bud
    • Petals are brightly colored to attract pollinators
    • Stamens consist of a filament and an anther
    • Anthers contain pollen sacs
    • Style is a long slender neck
    • Stigma is a sticky landing platform for pollen
    • Ovary contains ovules
    • Pistil refers to a single carpel or group of fused carpels

    Flower Types

    • Complete flowers have all parts (sepals, petals, stamens, pistils)
    • Bisexual flowers have both male and female parts
    • Unisexual flowers have only male or female parts

    Plant Reproduction Methods

    • Vegetative reproduction: part of the plant grows into a new plant (e.g., cuttings)
    • Spore formation: asexual reproduction where spores are produced and released to grow into new plants

    Animal Reproduction

    • Asexual reproduction allows organisms to reproduce without locating a mate
    • Fission: splitting of a parent into two or more individuals
    • Budding: outgrowth of new individuals from existing ones
    • Fragmentation: breaking of the body into pieces; some develop into adults
    • Regeneration: regrowth of lost body parts

    Reproductive Variations

    • Metagenesis: alternation between asexual and sexual reproduction (e.g., Obelia)
    • Parthenogenesis: development of an unfertilized egg into an adult organism
    • Hermaphroditism: one organism producing both eggs and sperm

    Plant Nutrition

    • Autotrophs produce their own food (photoautotrophs use sunlight, chemoautotrophs use chemicals)
    • Heterotrophs obtain energy from other organisms

    Plant Development

    • Gymnosperms have both male and female parts in separate structures

    Animal Nutrition

    • Herbivores: eat only plants
    • Carnivores: eat meat
    • Omnivores: eat both plants and animals
    • Substrate feeders: live in or on their food source
    • Filter feeders: strain small organisms from water
    • Fluid feeders: suck fluids from living organisms
    • Bulk feeders: eat relatively large chunks of food

    Other Modes of Nutrition

    • Photoautotrophic: use sunlight to make food
    • Chemoautotrophic: use chemicals to make food
    • Saprophytic: obtain nutrients from dead organic matter
    • Parasitic: obtain nutrients from other organisms
    • Holozoic: ingest solid or liquid food
