vocab
what is archaea?
single-celled microorganisms that are genetically and biochemically distinct from bacteria, forming their own domain of life.
what is the cell theory?
all living things are composed of one or more cells, that the cell is the basic unit of life, and that all cells arise from pre-existing cells.
what is eukaryote?
an organism whose cells have a membrane-bound nucleus and other membrane-bound organelles
what is lichen?
Lichen is a composite organism formed by a symbiotic partnership between a fungus and an alga or cyanobacterium
what is the mitochondrion?
A mitochondrion is a double-membraned organelle found in the cytoplasm of almost all eukaryotic cells, known as the "powerhouse" because it generates most of the cell's energy.
what is bacteria?
single-celled microorganisms found all over the world
the metabolic process by which organisms convert glucose from food into usable energy in the form of ATP.
what is fungi
Fungi are a kingdom of eukaryotic organisms that are essential decomposers, playing a critical role in nutrient cycles
what is lipid?
Lipids are a diverse group of organic compounds that are insoluble in water and include fats, waxes, oils, steroids, and phospholipids
what is mitosis?
Mitosis is the process where a single eukaryotic cell divides into two genetically identical daughter cells
what is binary fission?
an asexual reproduction method where one cell divides into two genetically identical daughter cells
what is chromosome?
a thread-like structure made of proteins and DNA that contains the genetic information for an organism.
what is gene?
the basic physical and functional unit of heredity, made of DNA
what is lysosome?
what is nucleic acid?
essential biomolecules that store and transmit genetic information
what is binomial nomenclature?
the formal system of giving each organism a two-part scientific name, with the first part being the genus and the second part being the species identifier
what is diffusion?
the process of particles moving from an area of higher concentration to an area of lower concentration, driven by their random motion
what is Golgi apparatus?
a cell organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
type of cell division that reduces the number of chromosomes by half, creating four genetically unique haploid cells(gametes) from one original diploid cell
what is nucleotide?
A nucleotide is the basic building block of nucleic acids like DNA and RNA
what is a botanist?
a scientist who studies plants and their interactions with the environment
what is endoplasmic reticulum
a network of membranes within eukaryotic cells that folds, processes, and transports proteins and lipids.
what is homeostasis?
the body's ability to maintain a stable internal environment, such as body temperature, blood sugar, and pH levels, despite external changes.
what is metabolism?
the set of chemical reactions that convert food into energy to sustain life
what is organic compound?
a chemical substance that contains carbon, typically bonded to hydrogen and often other non-metal elements like oxygen, nitrogen, and sulfur. These compounds are the basis of life on Earth and include major biological molecules such as carbohydrates, lipids, proteins, and nucleic acids.
