Relate cell parts/organelles to their functions.

cell membrane  cell boundary  controls movement of materials in & out  recognizes signals cytoplasm  jelly-like material holding organelles in place vacuole & vesicles  transport inside cells  storage mitochondria  make ATP energy from sugar + O 2 nucleus  protects DNA  controls cell ribosomes  builds proteins ER  helps finish proteins  makes membranes Golgi apparatus  finishes, packages & ships proteins lysosome  food digestion  garbage disposal &recycling Animal Cell

central vacuole  storage: food, water or waste mitochondria  make ATP in cellular respiration chloroplast  make ATP & sugars in photosynthesis cell wall  support cell membrane  cell boundary  controls movement of materials in & out  recognizes signals Golgi apparatus  finish & ship proteins nucleus  control cell  protects DNA endoplasmic reticulum  processes proteins  makes membranes ribosomes  make proteins cytoplasm  jelly-like material around organelles nucleolus  make ribosomes

PSEUDOPODCILIA FLAGELLUM Found mostly in animal cells; all used for cell movement

Explain the role of cell membranes as a highly selective barrier (diffusion, osmosis, facilitated diffusion, and active transport).

Osmosis – diffusion of water

Compare and contrast, at the cellular level, prokaryotes and eukaryotes (general structures and degrees of complexity).

2.2: PROKARYOTES/EUKARYOTES

Use cellular evidence: cell structure cell number, cell reproduction modes of nutrition to describe the six kingdoms (Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia).

2.3 SIX KINGDOMS OF LIFE

Identify the reactants, products, and basic purposes of photosynthesis and cellular respiration. Takes place in the chloroplasts of plants Produces glucose plants convert to starch for storage, cellulose for structure and ATP for energy.

Takes place in the mitochondria Process produces ATP Aerobic respiration requires oxygen Anaerobic- no oxygen; fermentation; takes place in cytosol

2.4: Explain the interrelated nature of photosynthesis and cellular respiration in the cells of photosynthetic organisms. Plants are autotrophs- produce their own food Animals are heterotrophs-rely on other organisms for their nutrition (food).

Describe the cell cycle and the process of mitosis.

2.6: MITOSIS Explain the role of mitosis in the formation of new cells, and its importance in maintaining chromosome number during asexual reproduction. Purpose of mitosis is for growth and repair in somatic (body cells)

Viruses can contain DNA and RNA Viruses can not reproduce on their own They need to invade a host cell to reproduce Bacteriophages invade bacteria; inject their DNA into the host cell
