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
