Algal Physiology MCQs with Answers

Welcome to the Algal Physiology MCQs with Answers. In this post, we have shared Algal Physiology Online Test for different competitive exams. Find practice Algal Physiology Practice Questions with answers in Biology Tests exams here. Each question offers a chance to enhance your knowledge regarding Algal Physiology.

Algal physiology would explain the functional parts of algae to understand how their unique cellular structures support them in their roles and performances in aquatic ecosystems. The cell physiology of algae reveals detailed mechanisms describing how algae carry out basic life processes like photosynthesis, growth, and reproduction.

The structure of algae really acts as the basis for its physiology.

Algae belong to the kingdom of algae and have a wonderful variety of cell forms, from a simple unicellular body scheme to multicell structures highly complex, such as the seaweeds. The algal cell is the basic unit, an inner or outer cell wall, chloroplasts, and central vacuole. Chloroplasts with its photosynthetic tissue play a principal role in conversion of chemical energy into light-induced energy and producing oxygen and other organic compounds of crucial importance for aquatic food webs. Such processes in the cell physiology of algae include uptake of nutrients, gas exchange, and reproduction. Nutrients are taken directly into the cell through the walls of the cells, although in some instances, these cell walls may be permeable for gas exchange- a condition required for photosynthesis. However, the strategies of reproduction among algae are relatively varied-from simple cell division of unicellular forms to complex reproductive cycles of multicellular species.
