Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The seven divisions of organisms that are considered within the algae are the Euglenophyta, Chrysophyta, Pyrrophyta, Chlorophyta, Rhodophyta, Paeophyta, and Xanthophyta. These divisions are separated on the basis of various features including their morphology and the biochemistry of their pigments, cell walls, and energy-storage compounds. The colors of these various algae types differ according to their particular mixtures of photosynthetic pigments, which typically include a combination of one or more chlorophylls and various accessory pigments.

D Correct answer
Explanation

One of the simplest multicellular organisms is algae. They are seen growing in the freshwater of marine habitats. They are also eukaryotic organisms. Algae can grow rapidly when exposed to stagnant waters. An adequate amount of sunlight, temperature and aquatic habitat leads to the rapid growth of slimy, green patches containing chlorophyll called algae.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Binary fission is a form of asexual reproduction in Amoeba. Zoospore is the flagellated spores present in algae for the means of asexual reproduction. Conidia are unicellular asexually produced spores in penicillium. Hydra reproduces by budding by the use of regenerative cells. Sponge reproduce asexually by gemmules which are the internal buds found in sponges.

The correct answer is B.
