Weekly Quiz Competition
  • Question 1
    1 / -0
    The moss plants are characterised by
    Solution
    • Mosses belong to the division Bryophyta.
    • The protonema (a filamentous juvenile gametophyte) is the first part of the moss that develops from the germinating spore. 
    • The protonema will eventually produce leafy shoots.
    • Mosses are spore-producing plants that do not have vascular tissue.

    So, the correct answer is option D.
  • Question 2
    1 / -0
    Sieved septa/trumpet hyphae occur in
    Solution
    • Conducting tubes or trumpet hyphae are present in larger brown algae or kelps belonging to family Laminariaceae
    • The tubes possess sieve septa. They take part in the conduction of food materials. 
    • So, the correct answer is "Some large brown algae'.
  • Question 3
    1 / -0
    The largest algae is
    Solution
    Macrocystis is the largest algal form. Macrocystis is a genus of kelp or large brown algae. This genus contains the largest of all the Phaeophyceae or brown algae. Macrocystis has pneumatocysts at the base of its blades. Sporophytes are perennial, and individual stipes may persist for many years. It is common along the coast of the eastern Pacific Ocean. So option  B is correct.
  • Question 4
    1 / -0
    A part of North Atlantic ocean is covered by free floating brown alga. It is
  • Question 5
    1 / -0
    First land inhabitating plants are
    Solution
    • Bryophytes are considered as the first land inhabiting plants. 
    • Algae are exclusively aquatic whereas bryophytes are mostly terrestrial but depend on water for fertilization. 
    • Hence, they are called amphibians of the plant kingdom and hence the link between aquatic and terrestrial plants.
    Thus, the correct option is B.
  • Question 6
    1 / -0
    Antherozoids of moss are
  • Question 7
    1 / -0
    Prothallus represents the
    Solution
    • Prothallus is the gametophyte stage of pteridophytes. The spores are released and fall to the ground, where they develop into prothallus.
    • The prothallus produces antheridia and archegonia. These are exosphoric, flat, green, autotrophic, heart-shaped, multicellular, short-lived, small reduced, dorsiventral, free-living independent, and non-vascular.
    • So, the correct answer is option A.
  • Question 8
    1 / -0
    Green alga which can be used as an article of food due to its very high nutrient value is
    Solution
    • Algae are useful to man in a variety of ways. At least half of the total carbon dioxide fixation on earth is carried out by algae through photosynthesis. 
    • Chlorella a unicellular alga rich in proteins is used as a food supplement even by space travelers. Hence, Green alga which can be used as an article of food due to its very high nutrient value is Chlorella.
    • So, the correct answer is "Chlorella'.
  • Question 9
    1 / -0
    In addition to chlorophyll $$a$$, brown algae possess
    Solution
    • The members of Phaeophyceae or brown algae are found primarily in marine habitats. 
    • They range from simple branched, filamentous forms (Ectocarpus) to profusely branched forms as represented by kelps, which may reach a height of 100 meters. 
    • They possess chlorophyll a, c, carotenoids, and xanthophylls. Hence, in addition to chlorophyll a, brown algae possess Chlorophyll c.
    • So, the correct answer is "Chlorophyll c'.
  • Question 10
    1 / -0
    In which of the following sexual reproduction is unknown?
    Solution
    • All the given organisms belong to the phylum Chlorophyta. These are green and photosynthetic. 
    • Chlorella reproduces asexually through autospores, which are made within the body of the parent itself. These spores germinate to give rise to Chlorella.
    Thus the correct answer is option A.
