Q1.
In Funaria, the number of peristomial teeth is
Solution
(d) In Funaria, there are 32 peristomial teeth arranged in two rings of 16 each.
(d) In Funaria, there are 32 peristomial teeth arranged in two rings of 16 each.
Q2.
Select the correct statements.
Solution
(c) A mycorrhiza is a symbiotic association of a fungus with a roots system. The fungus provides minerals and water to the roots, in turn the roots provide sugar and N-containing compounds to the mycorrhizae. Some plants have the obligate association with mycorrhizae. For example, Pinus seeds cannot germinate and establish without the presence of mycorrhizae.

Q5.
Consider the following statements about sexual reproduction in brown algae?
I. Sexual reproduction may be oogamous isogamous or anisogamous
II. Union of gametes take place in water or within the oogonium
III. The gametes are pear-shaped and bear two laterally attached flagella
Which of the statements given above are correct?
Solution
(d) In brown algae, sexual reproduction is isogamous (in Ectocarpales), anisogamous (in Cutleriales) and oogamous (in Fucus, Laminaria, Dictyota, etc). In most of the brown algae, the gametes are pyriform form and flagellated. Fertilisation is external, i.e., the gametes fuse outside the gametangia in water
