Study Notes
Key Facts about Green Algae
- Storage Bodies: Starch grains are commonly found in the chloroplasts of green algae, serving as energy reserves.
- Vegetative Reproduction: Typically achieved through fragmentation, where parts of the algae break off and develop into new individuals.
- Chlorophyll Pigments: Members of the class Chlorophyceae commonly contain chlorophyll a and b, responsible for their green coloration.
- Cell Wall Composition: The rigid cell wall of green algae is primarily composed of cellulose, providing structural support.
- Sexual Reproduction: Oogamy is a type of sexual reproduction observed in green algae, characterized by the large, non-motile egg and smaller motile sperm.
- Coloration: The grass green color of green algae is mainly due to the presence of chlorophyll pigments that effectively capture light for photosynthesis.
- Food Storage Form: Some green algae store energy in the form of starch, allowing them to utilize it when needed.
- Food Storage Method: Food is stored primarily as starch grains within the chloroplasts, facilitating energy access.
- Fragmentation in Reproduction: Filamentous green algae like Spirogyra commonly exhibit vegetative reproduction by fragmentation.
- Sexual Variation: Isogamy is a form of sexual reproduction in which males and females produce gametes of similar size and form, showing variation in the sex cells.
- Cup-shaped Chloroplasts: The genus Cladophora commonly features chloroplasts that are shaped like cup-shaped spirals, contributing to its unique appearance.
Additional Insights
- Endosymbiotic Theory Support: The presence of distinct storage bodies and pigments in chloroplasts suggests a complex evolutionary history.
- Ecological Roles: Green algae play significant roles in aquatic ecosystems as primary producers, supporting food webs.
