What are the characteristics features of chlorophyceae?
General characteristics
- the body may be unicellular, colonial, filamentous or multicellular.
- They are usually green due to the presence of chlorophyll a, chlorophyll b and beta-carotene.
- The chloroplast may be discoid, cup-shaped (e.g. Chlamydomonas), spiral or ribbon shaped (e.g. Spirogyra)
What are two characteristics of chlorophyta?
Characteristics: Green colour from chlorophyll a and b in the same proportions as the ‘higher’ plants; beta-carotene (a yellow pigment); and various characteristic xanthophylls (yellowish or brownish pigments). Food reserves are starch, some fats or oils like higher plants.
What are the five characteristics of chlorophyceae?
Characteristics of Class Chlorophyceae:
- Fresh water or marine algae, with unicellular or multicellular body.
- Cells are eukaryotic, containing cellulose in the cell wall.
- Chief pigments include chlorophyll a and b, alpha, beta and gamma carotenes, lycopene, hexanthin, lentin, violaxanthin and astaxanthin.
What makes chlorophyta different?
General characteristics They are greenish in colour due to the abundance of chlorophyll pigments in the thylakoids. Accessory pigments, such as beta-carotene and xanthophylls, are present albeit few. Some species are single-celled whereas others are multicellular and macroscopic (e.g. Ulva sp.).
What are the 11 algae classes?
| Algae class | Photosynthetic pigments |
|---|---|
| Chlorophyceae (Green algae) | They are composed of pigments chlorophyll a and b |
| Phaeophyceae (Brown algae) | They have composed of pigments chlorophyll a, c, β- carotene, xanthophyll |
| Rhodophyceae (Red algae) | They are composed of pigment r-phycoerythrin and r-phycocyanin |
What is the five characteristics of green algae?
Photosynthetic pigments are similar to those of higher plants: chlorophyll a, chlorophyll b, carotenes and xanthopylls. Food reserve is Starch. Chloroplasts generally contain pyrenoids for storage of starch. Vegetative reproduction occurs by fragmentation, stolons and tubers.
Is chlorophyta an order?
Classification of the Chlorophyta, treated as all green algae, according to Hoek, Mann and Jahns 1995. In a note added in proof, an alternative classification is presented for the algae of the class Chlorophyceae: Class Oedogoniophyceae (order Oedogoniales) Class Chlorophyceae (order Chlorellales)
Is Chlorophyta an order?
What are the examples of Charophyta?
The phylum Charophyta includes the following classes:
- Klebsormidiophyceae.
- Phragmoplastophyta.
- Charophyceae.
- Coleochaetophyceae.
- Mesotaeniaceae.
- Zygnematophyceae.
What are the five characteristics of algae?
Characteristics of Algae
- Algae are photosynthetic organisms.
- Algae can be either unicellular or multicellular organisms.
- Algae lack a well-defined body, so, structures like roots, stems or leaves are absent.
- Algaes are found where there is adequate moisture.
- Reproduction in algae occurs in both asexual and sexual forms.
What is the life cycle of Laminaria?
The life cycle of Laminaria has heteromorphic alternation of generations which differs from Fucus. At meiosis the male and female zoospores are produced separately, then germinate into male and female gametophytes. The female egg matures in the oogonium until the male sperm fertilizes it.
