cell membrane
control what goes in and out of cell
nucleus
brain of cell
cytoplasm
Holds other organelles in place
mitochondria
makes energy
golgi apparatus
packs proteins
endoplasmic reticulum
transports proteins
ribosomes
makes proteins
lysosome
disposes waste
epithelial tissue
sheets of cells that cover the exterior surfaces of the body
nervous tissue
allows the propagation of electrochemical signals to form that communicate between different regions of the body
muscle tissue
responds to stimulation and contracts to provide movement and occurs to skeletal, smooth, cardiac
connective tissue
binds the cell and organs of the body together and functions in the protection support and interrogation of all body parts
hair
has various functions, protection against external factors, sebum, apocrine swear and pheromones production and thermoregulation
hair follicle
anchors each hair into the skin
hair root
main function - uptake of water and nutrients from the rhizosphere
nails
function- protecting digits and contributing to tactile sensation
lunula
primary structural role is defining the free edge of the distal nail plate
cuticle
diffusion barrier limiting water& solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage as well as pest and pathogen attack
nail root
produces most of the volume of the nail and the nail bed
pores
they allow sweat and oil to escape through your skin
