phosphoid bilayer

what makes up the cell membrane

hydrophillic

loves water

hydrophobic

hates water

blood cell

skin cell

nervous cell

sperm cell

egg cell

isotonic

solute is equal inside and outside the cell

hypertonic

solute is greater outside the cell than inside the cell. water flows out.

hypotonic

solute is greater inside the cell than outside the cell. water flows in.

active transport

transports using cellular energy - atp

passive transport

requires no energy, from high concentration to low concentration (diffusion)

osmosis

the flow of water from high to low.

exocytosis

ejection of substances from cell. ex: Mucos, hormones

endocytosis

large particles enter the cell. ex: white blood cells

filtration

high pressure to low pressure without energy

epithelial tissue

tightly packed, found in sheets. lines, protects, absorbs, and secretes.outer layer of skin, inner cheeks, endocrine glands.

connective tissue

support, connects. bone, cartilidge, fat, blood.fibers, minerals, few cells.

muscle tissue

movement, skeletal, cardiac, smooth. long and stringy cells, capable of shortening.

nervous tissues

communication and coordination - brain, spinal cord, nerves. irregular shapes, neurons and supporting cells.

solute pumping

substance through membrane against concentration gradient.
