Question

How many of the given below features are associated with members of chrysophyta?
(a) chief 'producers' in the oceans
(b) Shows photoautrophic nutritiion
(c) Zygote develops into an auxospore
(d) From gritty soil
(e) Diatoms may be pennate type or centric type depending upon the symmetry

• A. Three
• B. Five
• C. Four
• D. Two

Answer 1

The correct option is C Four

Characteristics of Chrysophyta -

Chrysophyta is also known as golden brown algae. They are considered as the primary source of food for zooplankton. Brown algae show photoautotrophic nutrition. Brown algae are unicellular marine or freshwater protists. in some species of diatoms, a specialised cell called auxospore are produced during their life cycle. Auxospore plays important role in growth, sexual reproduction and dormancy. Diatoms may be the pennate type (bilateral symmetry) or centric type (radial symmetry).

So, the correct answer is ' Four'
