Reserve food in the form of floridean starch and the soluble sugar-floridoside is found in
1 Phaeophyta
2 Chlorophyta
3 Cyanophyta
4 Rhodophyta.
Explanation:
In Rhodophyta, reserve food material is floridean starch. Floridean starch (which stains red with iodine solution) and also soluble sugars called floridoside and glycerol compounds. Rhodophyta are the only ones not to produce motile forms. Example of red algae are Porphyra and Gelidium.

Hydrocolloid carrageen is obtained from:
1 Phaeophyceae only
2 Chlorophyceae and Phaeophyceae
3 Phaeophyceae and Rhodophyceae
4 Rhodophyceae only
Explanation:
Hydrocolloid are water holding substance for eg. Carrageen, which is obtained from red algae. Carrageen is extract from red seaweed commonly known as Irish moss (Chondrus Crispus). It is used as a thickener and emulsifier and commonly found in processed dairy products.
