Study Notes
Most Advanced Algae
- Ancestors of the plant kingdom
Reproduction
- Asexual reproduction occurs through zoospores, aplanospores, and hypnospores
- Sexual reproduction is classified into three types: isogamous, anisogamous, and oogamous
Forms of Algae
- Algae can be unicellular, filamentous, colonial, or parenchymatous
Unicellular Algae
- Chlamydomonas: characterized by motility, flagella, and variation in sexual reproduction
- Chlorella: non-motile, lacks flagella, and is rich in proteins
- Chlorella is used as food for space travelers and is the organism in which the Calvin Cycle (C3 cycle) was discovered
- It is a source of chlorophylls and antibiotics
- Chlorella is also known for its umbrella-shaped cells and is sometimes referred to as the "umbel plant"
- Hamerling experiments were conducted on Chlorella
Colonial Algae
- Colonial algae consist of a fixed number of cells in a colony, known as a coenobium
- Volvox: a motile colony
- Hydrodictyon: a non-motile colony
Filamentous Algae
- Cells are arranged to form filaments
- Spirogyra: also known as "pond silk"
- Ulothrix: also known as "pond weed"
Parenchymatous or Thalloid Algae
- Ulva: an example of a parenchymatous algae
