salient feature of Division phacophycene?
Answers
Answer:
A fallacy of division is the error in logic that occurs when one reasons that something that is true for a whole must also be true of all or some of its parts.
An example:
The second grade in Jefferson elementary eats a lot of ice cream
Carlos is a second-grader in Jefferson elementary
Therefore, Carlos eats a lot of ice cream
The converse of this fallacy is called fallacy of composition, which arises when one fallaciously attributes a property of some part of a thing to the thing as a whole.
If a system as a whole has some property that none of its constituents has (or perhaps, it has it but not as a result of some constituent having that property), this is sometimes called an emergent property of the system.
The term mereological fallacy refers to approximately the same incorrect inference that properties of a whole are also properties of its parts
Answer:
I think your question was about Phaeophyceae (Brown algae).
1. Plant body is immobile, multicellular and highly differentiated both externally and internally.
2. They range from simple microscopic heterotrichous filament (Ectocarpus) to largest alga (Macrocystis Pyrifera), which attains a length of 60-90 meters.
3. Commonly the plant body is differentiated into hold fast, a short or elongated stipe and an expanded blade. The blade performs photosynthesis and bears reproductive structures. Many species remain afloat by having air bladders.
4. The photosynthetic pigments include chlorophyll a, chlorophyll c, β-carotene and xanthophylls like lutein, Fucoxanthin, Flavoxanthin and Violaxanthin.
5. The cell wall is differentiated into outer and inner layers. The outer mucilaginous layer has fucinic and alginic acid, but the inner layer is mainly cellulosic.
6. The cells usually have many small vesicles and white granules. The granules are called fucosan vesicles.
7. The reserve foods are commonly laminarin and mannitol. Sucrose and glycerol are also present in some members.
