Study Notes
- Prokaryotes are ancient organisms lacking a nucleus and true membrane-bound organelles, including bacteria and Archaea.
- Prokaryotes can be spherical (cocci), rod-shaped (bacilli), or spiral-shaped (spirilla).
- Prokaryotes reproduce asexually mainly through binary fission.
- Prokaryotes gain genetic diversity through transformations, transductions, and conjugations.
- Prokaryotes can obtain energy through various methods like phototrophy and chemotrophy.
- The term "protist" is used to describe diverse eukaryotic organisms that are not animals, fungi, or plants.
- Protists come in various morphologies, physiologies, and ecologies.
- Most protists are microscopic and unicellular but some are multicellular like Caulerpa.
- Fungi are multicellular organisms with a mycelium, which is a mesh of threadlike filaments.
- Asexual reproduction in fungi occurs through budding or spore production by mitosis.
- Sexual reproduction in fungi involves fusion of hyphal tips, creating a dikaryotic cell, and subsequent meiosis.
- Fungi have beneficial partnerships with other organisms through mycorrhiza and lichens.
- Angiosperms are plants with seeds enclosed in an ovary.
- Flowers in plants have sepals, petals, pistils, and stamen, and their primary function is to attract pollinators.
- Fruits in plants aid in dispersal, usually through animals or by wind.
- Angiosperms undergo double fertilization, where one sperm fertilizes the egg and the other forms the endosperm.
