Heterospory What is Heterospory? Heterospory is the development of spores of various sizes and sexes by land plant sporophytes. The smaller microspore is male, while the larger megaspore is female. Several plant groups, including clubmosses, arborescent horsetails, and progymnosperms, independently evolved heterospory from isospory during the Devonian period. This happened as a result of the…
Photoheterotroph Examples & Photoheterotroph Energy Source Photoheterotroph What are Photoheterotrophs? Photoheterotrophs are organisms that use light as an energy source but do not produce their own food. These organisms can be found in all environments on Earth, from the deep ocean to deserts. Phototrophs are a type of photoheterotrophic organism that uses light to make…
Chemoautotroph Autotrophs are organisms that can produce their own food with the help of sunlight, water, and minerals. Those that make their food by using chemicals found in their environment are called chemoautotrophs. Chemosynthesis is the process by which chemoautotrophs feed on chemicals like ammonia and sulfides. This is often because it uses inorganic compounds…

Totipotency in Plants The capability to form a full-plant from a single cell. Plants that are totipotent can regenerate their cells or tissues, which is plants’ ability to replace themselves through natural growth. If a plant cannot regenerate, it will not grow as well as those who do have the capability. Some plants are more…
Totipotency in Plants Totipotency is the cell’s ability to generate all of the mature organism’s differentiated cells, tissues, and organs. Totipotent cells are found in plants and sometimes animals. The root word “totipotent” means “having all potentialities.” Totipotent cells are cells that have the ability to give rise to all of the tissues of a…
