tissue
epithelial
connective
muscle
nervous
examples
skin, stomach lining, respiratory tract
loose, dense, cartilage, bone, blood, lymph
skeletal (voluntary movement) cardiac smooth
central nervous system (brain, spinal cord); peripheral nervous system tissue (nerves, ganglia)
function
covers body surfaces and lines cavities
voluntary movement involuntary movement walls hollow organs (intestines, blood vessels)
contracts to cause movement, heat production
transmits electrical impulses, communication, regulation of body functions
structure
simple squamous, simple cuboidal
fat, bone, blood, cartilage
cardiac, smooth, skeletal
neurons (nerve cells), glial cells (supporting cells)
plants
tissue
epidermal
vascular
ground
meristematic
types
epidermis, cuticle, trichomes
xylem
phloem
parenchyma collenchyma sclerenchyma
apical (primary) lateral (secondary) intercalary (in some monocots)
function
protection, regulates CO2, prevents water loss, absorbs water/nutrients through roots
transports water and mineral roots->shoots
transports organic nutrients (sucrose) roots<-->shoots
photosynthesis, storage repair flexible support rigid support
primary growth (lengthening) secondary growth (thickening)
intercalary meristem, regrowth in some monocots
location
covering roots, stems, leaves, flowers
vascular bundles
vascular bundles
throughout the plant (cortex, pith) beneath epidermis in stems and petioles
fibers (vascular bundles), sclereids (seed coats)
tips of roots and shoots (apical meristems), vascular and cork cambiums
organs
