Neutrons TERM 2
DEFINITION 2 electrically neutral found within the nucleus TERM 3
DEFINITION 3 negative charge buzz around the nucleus (electrons and neutrons) TERM 4
DEFINITION 4 atoms or molecules combine, energy is released in bond formation (A+B->AB) TERM 5
DEFINITION 5 molecule is broken down energy is required (AB-> A+B)
something synthesized by cells, living organisms contain carbon and hydrogen example: Glucose TERM 7
DEFINITION 7 lack carbon and tend to be simpler compounds Example: Water (H2o) TERM 8
DEFINITION 8 High heat capacity solvent properties many chemical reactions occur in water ice floats TERM 9
DEFINITION 9 Have electrolytes which conduct electrical currents TERM 10
DEFINITION 10 0 to 6 Acidic 7 Neutral 8 to 14 Base's
Plant cells have cell walls that protects and maintains its shape Animal cells have an extracellular matrix which holds cells together in tissues and protects and supports them and prevents absorption of too much water Not in animal cells : central vacuole cell wall chlorplasts TERM 17
DEFINITION 17 The diversity of proteins that float like bugs in the phospholipids sea TERM 18
DEFINITION 18 animals secrete extracellular matrix this layer holds them together in tissues and it also have protective and supportive function plants : all cell walls protect the cells, maintain their shape and keep them from absorbing too much water :made from cellulose fiber TERM 19
DEFINITION 19 Chromatin, long DNA molecules associated proteins from long fibers, each contains one chromosome ; Nucleolus- produces ribosomes TERM 20
DEFINITION 20 responsible for protein synthesis produced in the nucleolus found in cytosol/cytoplasm of both
High heat capacity solvent properties many chemical reactions occur in water ice floats TERM 22
DEFINITION 22 Have electrolytes which conduct electrical currents TERM 23
DEFINITION 23 0 to 6 Acidic 7 Neutral 8 to 14 Base's TERM 24
DEFINITION 24 a biological molecule consisting of simple single monomer sugars, two monomer sugars, and other multi-unit sugars TERM 25
DEFINITION 25 fats-waxes, phospholipids and steroids, consisting mainly of carbon and hydrogen atoms linked by non polar covalent bonds and therefore mostly hydrophobic and insoluble in water
animals secrete extracellular matrix this layer holds them together in tissues and it also have protective and supportive function plants : all cell walls protect the cells, maintain their shape and keep them from absorbing too much water :made from cellulose fiber TERM 32
DEFINITION 32 Chromatin, long DNA molecules associated proteins from long fibers, each contains one chromosome ; Nucleolus- produces ribosomes TERM 33
DEFINITION 33 responsible for protein synthesis produced in the nucleolus found in cytosol/cytoplasm of both TERM 34
DEFINITION 34 ribosomes stud the outside of the membrane producing two main types of proten membrane proteins and secretory proteins the cell will actually export to the field outside the wall TERM 35
DEFINITION 35 synthesis of lipids (steroids) detoxifies your liver and your body from harmful substances your body will become use to the toxin and then you will need to take more and more enzymes are built into the membrane of the smooth ER
Shipping center- a receiving dock for the transportation vesicles moving products made in the ER- then it adapts the products and "ships" them off to other organelles TERM 37
DEFINITION 37 "breakdown body" a membrane enclosed sac of digestive enzymes these enzymes can break down practically anything have a separate area to do this so they don't endanger themselves TERM 38
DEFINITION 38 unique to the photosynthetic cells of plants and protists, are the organelles that perform photosynthesis three major compartments: mitochondria, cellular respiration, and process harnesses energy from sugars and other food molecules and converts it to another form of chemical energy called ATP TERM 39
DEFINITION 39 a network of fibers extending throughout the cytoplasm- serves as both skeleton and "muscles" for the cell, functioning in both support and movement TERM 40
DEFINITION 40 propel the cell by whip like motion- Eukaryote like sperm
Cars: Use fuel rich in chemical energy like food, which combines with oxygen which leads to combusting where heat is let off and kinetic energy of movement is produced waste products= Carbon dioxide and water, just like humans Humans: food and oxygen, heat, energy for cellular work, waste: carbon dioxide and water
