Plant Physiology Quiz

Plant Physiology Overview

• The main focus of plant physiology is the study of the functions and processes that occur within plants.

Related Fields

• Plant physiology is closely related to the field of botany.

Fundamental Processes

• Plant physiologists study the fundamental processes that occur in plants, including photosynthesis, respiration, nutrition, transport, and growth.
• These processes involve the exchange of materials and energy between plants and their environment.

Biochemistry of Plants

• The subdiscipline of plant physiology that focuses on the biochemistry of plants is known as plant biochemistry.

Scale of Study

• Plant physiologists study processes at various levels of scale, from molecules and cells to organs and whole organisms.
• They also examine the interactions between plants and their environment at the ecosystem level.

Energy Source

• The main source of energy for plants is sunlight, which is used to power photosynthesis.

Viridiplantae

• The clade Viridiplantae includes all organisms that are characterized by the presence of chlorophyll and the ability to perform photosynthesis, including plants, green algae, and cyanobacteria.

Plant Diversity

• There are approximately 400,000 known plant species.

Photosynthesis

• The primary pigment used by plants in photosynthesis is chlorophyll.

Parasitic Plants

• Parasitic plants that have lost the genes for chlorophyll and photosynthesis use their host plants as a source of energy.
