Question

Give the salient features and importance of chrysophytes?​

Answer 1

Answer:

In is one of the major groups of the kingdom Protista which includes diatoms.  Diatoms occur in all aquatic (fresh water and marine) and moist terrestrial habitats.  The cell walls have silica and form two overlapping shells which fit together as in a soap cases.

Answer 2

Chrysophytes are protists that act like plants and can be found in both salty and freshwater environments.

• The following are some of the most important properties of chrysophytes: -
• Chrysophytes have two different lengths of flagella. Chrysophytes are motile, and their motion is regulated by flagella. Longer flagella provide motility, while a shorter one rotates heliocentrically.
• Chrysophytes produce golden yellow pigments that give them their colour. The presence of this pigment aids in the identification of chrysophytes. Fucoxanthin is the pigment they generate.
• The chrysophytes have cellulose and silica in their cell walls. This gives them stiffness and structural support. They are able to survive in freezing temperatures because of this. Chitin is also found on the cell walls of some chrysophytes.
• Chrysophytes are unicellular organisms with organelles that are membrane-bound.
• They are generally calcium-deficient. Bacillariophyta, Chrysophyceae, and Xanthophyceae are the three major types of chrysophytes.
• Some chrysophytes are amoeboid, and some have extremely complicated life cycles that include the creation of numerous nuclei.
• Chrysophytes is one of the most common causes of eutrophication in some water bodies, where nitrogen-rich topsoil washes into the water and chrysophytes consume and multiply the nutrients.
