  1. Algae

  2. Liverworts

  3. Mosses

  4. Ferns.

Show answer
Correct Option: A
Explanation:
To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved. In algae, vascular tissue is not necessary as the entire body is in contact with the water, and the water and gases simply enters the algae through diffusion.
So, the correct answer is 'Algae'

So, the correct answer is 'Alva'

The most important character which is used in classifying different algae is

evs a treat for mosquito algae: benefits and harmful effects basics of algae types of microorganisms

  1. Cell wall structure

  2. Habit

  3. Types of pigments

  4. None of the above

Show answer
Correct Option: C
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.

Slimy, green patches in ponds or in stagnant water is

evs a treat for mosquito algae: benefits and harmful effects basics of algae types of microorganisms

  1. Fungi

  2. Bryophytes

  3. Bacteria

  4. Algae

Show answer
Correct Option: D
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.


So, option D 'Algae' is the correct answer.

Cell wall of Chlamydomonas possesses _____________.

  1. Cellulose

  2. Glycoproteins

  3. Hemicellulose

  4. Proteins only.

Show answer
Correct Option: B
Explanation:

The cell wall of the unicellular green alga Chlamydomonas consists of glycoproteins, which also occurs in the extracellular matrix of multicellular green algae and higher plants.

So, the correct answer is 'Glycoproteins'

Algae have cells made up of

  1. cellulose, galactans and mannans

  2. hemicellulose, pectins and proteins

  3. pectins, cellulose and proteins

  4. cellulose, hemicellulose and pectins.

Show answer
Correct Option: A
Explanation:

Algae have a cell wall containing cellulose, Galatians, and mannan.

So, the correct option is 'cellulose, Galatians, and mannans'.

Heterocysts and present in ______________.

evs a treat for mosquito algae: benefits and harmful effects basics of algae types of microorganisms

  1. Riccia

  2. Ulothrix

  3. Albugo

  4. Nostoc

Show answer
Correct Option: D
Explanation:

Heterocysts are the thick-walled cells formed in cyanobacteria (Nostoc) and are responsible for nitrogen fixation in the state of nitrogen starvation by the use of enzyme nitrogenase. These are specialized pale yellow structures  which help in nitrogen formation during aerobic conditions.

 

The correct answer is D.

  5. A-4; B-1; C-3; D-5; E-2

Show answer
Correct Option: B
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.
