Answers
3.heterokont
4. floridean starch
5.Phaeophyceae
6.cup-shaped
7.single girdle-shaped or band-shaped chloroplast
8.hypnospore.
9.aplanospores
10.haplontic
Explanation:
1.the dissimilar flagella with reference to their length and appearance types, are described as heterokont. For example Diatoms, brown algae.
2.Floridean starch is a type of a storage glucan found in glaucophytes and in red algae (also known as rhodophytes), in which it is usually the primary sink for fixed carbon from photosynthesis.
3.Fucus are brown algae which is found in the intertidal zones of rocky seashores. These algae belong to the class Phaeophyceae and order Fucales, which stored food in the form of laminarin, mannitol, and oil. Mannitol is stored as a food reserve in Fucus.
4. They are common littoral seaweed growing in the hard-rocky areas of the sea.
5.each spherical or ovoid cell has two equal flagella with a pair of contractile vacuoles at their base and a large cup-shaped chloroplast with a single pyrenoid.
6.Ulothrix is a genus of filamentous green algae which are found in marine and fresh waters habitats. They have a single girdle-shaped or band-shaped chloroplast near the peripheral region of the cytoplasm.
7.Hypnospores are non-motile, thickened asexual spores in Chlamydomonas. They are the means of asexual reproduction in Chlamydomonas. The protoplasts of palmella develop a thick wall to form the hypnospores.
