Biology EOC review

one celled

many celled with levels of organization

oppspring are genetic clones of parent

offspring have genetic vatiation from parent

• energy is required for life processes
• autotrophs make their own food
• heterotrohs eat other organisms for food

Maintenance or regulation of body conditions suc as body temperature, blood sugar level, water balance

is the genetic material that codes for proteins of all organisms.

responding to the biotic and abiotic factors in the environment are key to survival

increase in the amount of living matter either by cell division or cell enlargement

any change from conception to death-embryonic, puberty, aging

structures, behaviors, or processes that aid in an organisms survival are passed on from parent to offspring

composed of momsaccharieds primarily glucose

composed of amino acids-do most of the work in organisms and are major strutural components

composed of nucleotides-either DNA or RNA

controlled by the action of enzymes

proteins that function to spped up chemical reations in the cell

• Cells are baic unit of life
• Cells come from existing cells
• All organisms are composed of cells

• simple
• has no nucleus
• has no MB organelles
• includes bacteria

• complex
• has a MB nucleus
• has MB organelles
• includes protists, fungi, plants, and animals

photosynthesis

cellular respiration......power house of the cell

protien synthesis (made)

storages

contains DNA and controls cell actions

site of ribosome formation

protiens travel on

modifies and refines the protiens depending on where they are going

• has cell wall
• has chloroplasts/plastids
• has large vacuole

• no cell wall
• has no plastids/chloroplasts
• has small vacuoles

controls homeostasis (balance)

composed of a phospholipid bilayer with embedded proteins "gates"

acts as a selectively permeable boundary around the cell

moves substances from high to low concentrations down their concentration gradient

the diffusion of water from high to lower water concentrations down to its concentration gradient

movement of a substance down its concentration through a transport protein channel

requires energy-moves substances against the concentration gradient from low to high concentrations
