[1] [6] [7] Different members of the genus have been found in temperatures ranging from 11.4 to 21.6 °C, and a pH between 6.2 and 7.5. Phacus organisms are found in a range of freshwater environments (some more acidic or alkaline than others), prefer cooler temperatures, and on average exist in more neutral pH aquatic habitats. [6]
The cytochrome b 6 f complex (EC 1.10.99.1) (also called plastoquinol—plastocyanin reductase) is an enzyme related to Complex III but found in the thylakoid membrane in chloroplasts of plants, cyanobacteria, and green algae.
Chloroplasts can only be found in plants and algae, and they capture the sun's energy to make carbohydrates through photosynthesis. Diagram of the endomembrane system Endoplasmic reticulum : The endoplasmic reticulum (ER) is a transport network for molecules targeted for certain modifications and specific destinations, as compared to molecules ...
The result of this is that water, as a medium, is often easily depleted of CO 2 and is slow to gain CO 2 from the air. Finally, CO 2 equilibrates with bicarbonate (HCO − 3) when dissolved in water, and does so on a pH-dependent basis. In sea water for example, the pH is such that dissolved inorganic carbon (DIC) is mainly found in the form of ...
The morphological similarity between chloroplasts and cyanobacteria was first reported by German botanist Andreas Franz Wilhelm Schimper in the 19th century [196] Chloroplasts are only found in plants and algae, [197] thus paving the way for Russian biologist Konstantin Mereschkowski to suggest in 1905 the symbiogenic origin of the plastid. [198]
In some plants such as cacti, chloroplasts are found in the stems, [186] though in most plants, chloroplasts are concentrated in the leaves. One square millimeter of leaf tissue can contain half a million chloroplasts. [11] Within a leaf, chloroplasts are mainly found in the mesophyll layers of a leaf, and the guard cells of stomata.
Chlorella: This form of alga is found in freshwater and contains photosynthetic pigments in its chloroplast. Klamath AFA: A subspecies of Aphanizomenon flos-aquae found wild in many bodies of water worldwide but harvested only from Upper Klamath Lake, Oregon. Spirulina: Known otherwise as a cyanobacterium (a prokaryote or a "blue-green alga")
In the experiment, the plants in water deficit were analysed with fluorescence imaging technique. This form of analysis detected increased levels of PTOX, and NAD(P)H activity within the plant. [3] An increase in these two molecules led to the initiation of chlororespiration. [3] N-propyl gallate was also added to these water deficit plants.
