  • Question 1
    1 / -0
    Bryophyta are ecologically important plants as they are
    Solution
    Bryophytes can colonize any rock, soil or any barren land. They have the ability to absorb water from rain and mist and to trap nutrients dissolved in rain and mist drops. They Dead and decaying bryophytes release nutrients and make a path for soil formation. Hence, they are the first organism in primary succession. Thus, the correct answer is option B.
  • Question 2
    1 / -0
    The plants which are differentiated into roots, stems and leaves but do not bear flowers and seeds are classified as
  • Question 3
    1 / -0
    Which of the following exhibit the characteristics given below?
    X - Form a green scum over wet soil
    Y - Closer to bacteria
    Z - Pigments mask the chkiriohyll
  • Question 4
    1 / -0
    Which one of the following is called as horsetail?
    Solution
    The name horsetail, often used for the entire group, arose because the branched species somewhat resemble a horse's tail. Similarly, the scientific name Equisetum derives from the Latin Equus (horse) + seta (bristle).
    Equisetum is a living fossil as it is the only living genus of the entire class Equisetopsida.
    Therefore, the correct answer is option C.

  • Question 5
    1 / -0
    Which of the following is called as club moss?
    Solution
    Lycopodium is a genus of clubmosses, also known as ground pines or creeping cedar
    They are flowerless, vascular, terrestrial or epiphytic plants, with widely branched, erect, prostrate or creeping stems, with small, simple, needle-like or scale-like leaves that cover the stem and branches thickly. The leaves contain a single, unbranched vascular strand and are microphylls by definition.
  • Question 6
    1 / -0
    Movement of gametes of Spirogyra is
    Solution
    Movements of locomotion are generally very fast movements which may be:
    (A) Autonomic or spontaneous and
    (B) Induced or paratonic.
    These movements are very common among lower plants and unicellular organisms. These movements are relatively faster and more pronounced. Autonomic movements, i.e., the spontaneous locomotory movements maybe 
    (i) Ciliary : due to beating of cilia as in protist, Paramecium. 
    (ii) Amoeboid : by the formation of pseudopodia as in Amoeba. Fresh water alga, Spirogyra also produces non flagellate gametes which show amoeboid movement 
    (iii) Cyclosis : due to streaming of cytoplasm.
    (iv) Gliding : as seen in coelenterate animal, Hydra.
    Thus, the correct answer is option C.
  • Question 7
    1 / -0
    A student observed an algae with chl-a, chl-d and phycoerythrin, it should belong to
    Solution
    Red algae are red because of the presence of the pigment phycoerythrin; this pigment reflects red light and absorbs blue light. Because blue light penetrates water to a greater depth than light of longer wavelengths, these pigments allow red algae to photosynthesize and live at somewhat greater depths than most other "algae". Some rhodophytes have very little phycoerythrin, and may appear green or bluish from the chlorophyll and other pigments present in them.
    Thus, the correct answer is option B.
  • Question 8
    1 / -0
    Ovules are absent in
    Solution
    • The division Pteridophyta includes a group of primitive vascular plants, commonly called pteridophytes in which the male sex organs are called antheridia and female sex organs are called archegonia. Antheridia produce antherozoids and archegonia encloses the egg cell. Fertilization requires water. The diploid zygote is retained in the archegonial venter where it develops into an embryo. Subsequently, it becomes a young sporophyte and grows into an independent adult plant. 
    • Gymnosperms and angiosperms are seed-bearing plants and possess ovules within female sex organs that convert into a seed after fertilization.

    So, the correct answer is option A.
  • Question 9
    1 / -0
    Fern belongs to the subgroup
  • Question 10
    1 / -0
    Mannitol is the stored food in
    Solution
    Fucus belongs to the classification Phaeophyceae (brown algae). Chlorophyll a, c, carotenoids and xanthophyll are the pigments found in phaeophyceae. Colour can vary from olive green to various shades of brown. The colour variation depends on the amount of xanthophyll and fucoxanthin.
    Food is stored as complex carbohydrates; in the form of laminarin or mannitol. The cell wall of vegetative cells is composed of cellulose and is covered by a gelatinous coating of algin. Protoplast contains plastids, centrally located vacuole and nucleus.
    Gracillaria and Porphyra belong to red algae. Chara belong to green algae.
    Thus, the correct answer is option D.
