Phagocytosis - Process by which certain cells encompass relatively large particles with the aid of pseudopods.
Phagosomes - Membrane bag containing the particle captured by the phagocytosis process.
Phanerogama - See sperm.Vegetative phase - Phase of life where the being does not have developmental or multiplication properties. Its metabolism is very low and its interaction with the environment is practically nil.
Ecological factor - refers to the factors that determine the ecological conditions in the ecosystem.
Typhoid fever - Bacterial disease caused by Salmonella typhi.
Fibrinogen - Protein present in blood, precursor of fibrin; participates in blood clotting.
Fillet - Elongated part of the stamen that supports the anther, in the androceu, male reproductive apparatus of the vegetable
Phytoplankton - set of floating plants, such as algae, from an aquatic ecosystem.
Photosynthesis - Biochemical process that allows plants to synthesize complex and high energy organic substances from simple and low energy mineral substances. For this, they use solar energy that they capture in chlorophyll molecules. In this process, the plant consumes carbon dioxide (CO2) and water, releasing oxygen (O2) into the atmosphere. It is the process by which plants use sunlight as an energy source to form nutritive substances.
Flagellated - See Mastigophora.
Scourge - Filiform structure present in the cell surface, generally longer than the eyelash, whose function is to promote movements (for swimming or food capture).
Phloem - (From Greek: phloos, bark) Vascular tissue that conducts carbohydrate and other organic molecules from leaves to other parts of the plant; It consists of sieved cells (in the gynosperms) or sieved tubes and companion cells (in the angiosperms), parenchyma and fibers. Also called a Liberian or Liber vessel.
Oxidative phosphorylation - Formation of ATP molecules with energy from oxidation processes.
Acyclic Photophosphorylation - Light-mediated set of chemical reactions that activate certain substances to absorb phosphorus atoms, retaining at these bonds chemical energy.
Photolysis - Light-mediated reaction that breaks down a given molecule.
Fraternal - Fraternal twins. Siblings who, although sharing the same gestation period, derive from different eggs, fertilized by different sperm. also called bivitelines. These brothers do not have the same gene inheritance. Therefore they may or may not belong to the same sex.
Fruit - (From Latin: fructus) is the ovary developed and matured after fertilization.
Achromatic Spindle - Filaments of proteins formed during cell division that bind to the kinetochore of duplicate chromosomes to promote their separation.
