Terminology Flashcards
non-living part of an ecosystem
Abiotic
Living part of an ecosystem
Biotic
smallest unit of life
Cell
splitting of a single cell cell into two cells
Cell Division
double layered, thin barrier, surrounding the cell to control the entry and the exit of certain substances
Cell Membrane
cells are basic unit of life, all organisms are made up of one or more cells and cells arise from one-existing cells
Cell Theory
outer covering in plant cells, provides protection and maintenance of its shape
Cell Wall
micro tubules found next to the nucleus of animal and some protoctists(protists)
Centrioles
they move chromosomes around a by forming fibers during cell division
spindle
a group within phylum in the classification system
Class
an organelle in plant cells that contain chlorophyll and convert sun, carbon dioxide and water into glucose during photosynthesis
Chloroplast
made up of DNA and store in the nucleus, which contains the instructions for traits and characteristics
Chromosomes
fluid part of the cell containing the organelle and cell membrane
Cutoplams
cell having two sets of chromosomes
Diploid
have nucleus surrounded by a nuclear membrane
Eukaryote
found near the nucleus and is made up of number of flattened sacs called CISTEMAE
Endoplasmic Reticulum
level below order in the classification system
Family
level below family in the classification system; group of closely related species
Genus
a stack of membrane-bound flattened sacs and responsible for the modification of proteins received from the ER
Golgi Apparatus
a cell having one set of chromosomes
Haploid
are membrane-bound spherical sacs which contain digestive enzymes used to break down material such as nonself microorganisms engulfed by phagocytes, to recycle food and capture bacteria
Lysosomes
broadest group in the classification system
Kingdom
type of cell division which result in gamete production
Meiosis
instrument that produces an enlarged image of an object
Microscope
round double membrane-bound organelles responsible for Aerobic Respiration
Mitochondria
a cell division in which two cells produced are identical to the parent cell
Mitosis
living things made up of more than one cell
Multicellular Organisms
a bi-layer membrane, which protects the nucleus by surrounding and acts as a barrier between the ell nucleus and organs of a cell
Nuclear Membrane
an important membrane found inside the nucleus;
It plays an vital role in the production of cell’s ribosome
Nucleolus
large cell organelle bounded by the nuclear membrane
Nucleus
also called infectious agent is a biological agent that causes disease to its host
Pathogen
level below kindom in the classification system
Phylum
organism whose cells do not contain in a nucleus
Prokaryote
are small spherical organelles, composed of two sub-units, which can be found in the endoplasmic reticulum; translate genetic information in the form of mRNA into proteins
Ribosomes
an interbreeding population of organisms, which can produce healthy and fertile offspring
Species
living organism made up of a single cell
Unicellular Organism
are membrane-bound sacs that are used to store or transport substances around the cell
Vesicles
an example of vesicles
Lysosomes
are essential larger vesicles, and they are formed by the joining together of many vesicles; in plant cell they are important in maintaining turgor pressure
Vacuoles
