Answer 1

Answer:

both a nd c.

A) In Chlorophyceae, the stored food material is starch and the major pigments are chlorophyll a and b.

C) In Rhodophyceae, floridean starch is the stored food and the major pigments are chlorophyll a, d and phycoerythrin.

Answer 2

Question:

The major pigments in green algae are ................and stored food is...........

O(A). Chla, Chld, Starch

O(B). Chla, Chl d, Floridean Starch

O (C). Chla, Chlb, Starch

O (D). Chla, Chlc, manitol

Answer:

The correct answer is option (c)

(c) Chla, Chlb, Starch

Explanation:

The three types of algae are:

• Green Algae
• Brown Algae
• Red Algae

Green algae is also known as Chlorophyceae.

Based on the presence of pigments the classfication is done.

• The pigments present green algae are Chlorophyll a, Chlorophyll b and carotene ( beta carotene ).
• The pigments present in Brown algae (Phaeophyceae) are Chlorophyll a, Chlorophyll c and fucoxanthin.
• The pigments present in red algae (Rhodophyceae) are Chlorophyll a, chlorophyll d and phycoerythrin.

The chlorophyll a and b in green algae is used for photosynthesis process.

The food stored in green algae is starch which is located in the chloroplast. Starch is the major food stored in green algae.

Due to the presence of chlorophyll the algae appears in green color.

By using these pigments the green algae prepare its own food (starch) by photosynthesis.

Starch is stored in green algae in the form of amylose and amylopectin.

Answer: The major pigments in green algae are Chlorophyll a and chlorophyll b and the major stored food in green algae is starch.
