Study Notes
Plant Reproduction
-
Non-Vascular Plants
- Simple plants without a vascular system
- Typically smaller due to limited water and nutrient transport
- Examples: Moss, Algae
-
Moss Life Cycle
- The dominant stage is the gametophyte, which produces male and female reproductive structures: antheridia and archegonia.
- Sperm from the antheridia swims through water to reach the archegonia, forming a zygote.
- The zygote develops into a sporophyte, dependent on the gametophyte for nutrients.
- The sporophyte produces spores through meiosis in a capsule at the end of a stalk (seta).
- Mature spores are released into the environment, completing the cycle.
-
Seedless Vascular Plants
- Simple plants with a vascular system
- Taller than non-vascular plants due to efficient water distribution
- Examples: Fern
-
Seeding Vascular Plants (Spermatophytes)
- Divided into two types: Gymnosperms and Angiosperms
- Seeds are derived from ripened seed-producing plants.
Angiosperms vs. Gymnosperms
-
Angiosperms
- Flowering plants with seeds enclosed within fruits/flowers.
- Rely on pollinators like bees.
- Examples: Apple tree, Sunflower.
-
Gymnosperms
- Seed-producing plants with uncovered seeds, typically found in cones.
- Examples: Pine trees.
Animal Reproduction
-
Asexual Reproduction
- Budding: Offspring grows from the parent's body. Example: Hydra.
- Gemmation: Organism develops gemmules (buds) that grow into new organisms. Example: Sponges.
- Fragmentation: Part of an organism develops into another. Example: Flatworms.
-
Sexual Reproduction
- Two organisms contribute genetic material to offspring, resulting in a new gene combination.
