VOCAB! Flashcards
CELLS
The smallest unit that can carry out the function of life. All living organism are composed of one or more cells.
What is metabolism?
Living organisms carry out a number of chemical reactions collectively known as metabolism
Metabolism is the process where living organisms carry out chemical reactions.
GROWTH
Where building outweights breaking down processes include two forms
Increase number of cells
Increase in size of individual cells
What is excretion?
Process that an organism uses to eliminate potentially harmful waste products created by metabolic processes
Excretion is the process by which organisms eliminate harmful waste products.
What is responsiveness or irritability?
Ability of organisms to sense and react to changes or stimuli in their environment
Responsiveness or irritability is the ability of organisms to sense and react to changes in their environment.
What is movement?
Ability of an entire organism to move or movement of individual cells or materials within or between cells of an organism
Movement is the ability of an organism to move or the movement of cells or materials within an organism.
Organ
Two or more tissue type can combine to form Organs
Examples are skin heart, bones, skeleton, liver.
organ system
Two or more organs that together carry out broad functions in the body
example organs of cardiovascular system the heart and blood vessel work together
Tissue
Group of similar cell in material outside then call the extracellular matrix come together to perform a common function as tissue. Example muscles membrane.
Chemical
The smallest level organization, tiny atoms to complex structures called molecules
anabolism
Smallest chemicals, combined to form larger one
Catabolism
such as building muscles and breaking down process
Organism
The organ system function together to make up working human body. It is called organism.
anatomy
Study of structure
physiology
study of function
Division of microscopic anatomy that study tissues
histology
take following two forms in multicellular organisms
reproduction
LEVEL OF ORGANIZATION
chemical level
cellular level
tissue
organ level
organ system level
organism level
diffusion of water through selectively permeable membrane
osmosis
isotomic
stay same
solute concentration is less than that inside the cell
basically more water inside less outside .
hypotonic
solute concentration is greater than that inside cell
water is less inside cell more outside
hypertonic
function as enzymes
Macromolecules
structure roles
movement
hormones
antibodies
can be used as fuel
proteins
Energy that is stored, ready to be released and used to do work
Potential energy
Energy that is motion, which means that work of some sort is been done
Kinetic energy
Build from monomers of nucleotide make up genetic material
nucleic acid
the main source energy in the human body is
ATP
adenosine triphosphase
lipid monomers
fatty acid
net movement of molecule of substances
higher concentration to lower is
diffusion
Most animal have 3 basic components
plasma membrane
cytoplasm (cells)
nucleus
substances cells has produced or ingested to a variety of destinations
Transport
provide cell with structure support mean of communication and cell identification
plasma membrane
(cell membrane/ plasmalemma)
network of protein filaments
cytoskeleton
contain most of cells DNA and primary for making most RNA
nucleus
bind to chemical messenger called ligands trigger sequence of events within cell when bound
receptor
speed up chemical reactions; vital to maintaining homeostasis
ENZYMES
give cells support and help maintain structural integrity
Structural support
Hold cells together ( adjacent cells) to one another . anchoring cells surging tissue and allowing cells to cells communicate
linker
allow specific molecules or ions to cross other membranes
channels
bind and transport substances across the membrane
carries
lipid molecules; stabilized plasma membrane fluid structure during temperature change
cholesterol
serve to identify cell as part of the body
cycloids and glycoproteins
