Which statement is wrong ?
- A Beryl is an example of cyclic silicate.
- B \(Mg_2SiO_4\) is orthosilicate.
- C Basic structural unit in silicates is the \(SiO_4\) tetrahedron.
- D Feldspars are not aluminosilicates.
Answer & Solution
Correct Answer
(D) Feldspars are not aluminosilicates.
Step-by-step Solution
Detailed explanation
Oomycetes (egg fungus) include water moulds, white rusts and downy mildews. In these, female gamete is smaller and motile, whereas male gamete is larger and non-motile. Isogametes are found in algae like Ultrix, Chlamydornonas, Spirogyra, etc., which are similar in structure, function and behavior. An isogametes are found in Chlamydornonas in which one gamete is larger and non-motile and the other one is motile and smaller. Oogamy is the fusion of non-motile egg with motile sperm. The gametes, differ both morphologically as well as physiologically. It occurs in Chlamydomonas, Fucus Chara, Volvox, etc.
