Cell Biology

Multicellular organism with a nuclei containing DNA (membrane enclosed organelles)

Phospholipids, Glycolipids , Cholesterol

Hydrophilic polar phosphate head with hydrophobic fatty acids tails, in the membrane, the most abundant

Hydrophilic head and hydrophobic acid tail, located in bilayer, gives stability - controlling membrane fluidity, sterol

Hydrophilic head and hydrophobic tail (steroid rings), surface of membrane, communication between cells - cell-cell recognition

Selectively permeable seal for cell, maintains constant internal environment (homeostasis), cell-cell communication (recognition), non recognition

Alpha helix (recognition, receptors), helical bundle (enzymes, transport, receptors), beta barrel (transport -> channel proteins)

Enzymes, anchorage, transporters

Membrane bound organelle, modifies and secretes proteins, transports lipids, creates lysosomes - Trans, medial, cis parts

Membrane bound vesicle containing digestive enzymes, destruction of damaged, deseased cells & bacteria, autophagy!

Membrane bound, ATP production with aerobic respiration, contains two membranes

Membrane bound, large organelle surrounded by nuclear envelope (membrane), contains nucleic acid (hereditary info) and RNA, controls the cell

Membrane bound, extention from nuclear membrane (envelope), ribosomes (rough), membrane & modified proteins in reticulum (network)

Membrane bound, extention from RER, synthesis of proteins and metabolism of fats and steroid hormones

Membrane bound vesicle, liquid with dissolved substances, plants have large main vacuole which is storage in cell

Lysosomes, vacuoles, secretory, transport, move chemicals and biomolecules around the cell where needed, crucial for cell

Non-membrane bound, cellulose (polysaccharide) fibres linked with hydrogen bonds, pectin, hemicellulose (polysaccharides), support cell structure, separates cell from environment, water permeable

Non-membrane bound, chitin, glucan & manan (polysaccharides), structural support, environmental stresses (osmotic shock)

Non-membrane bound, gram positive (single membrane) or gram negative (double membrane), structural support, protects from environmental stresses (osmotic shock)

Non-membrane bound, contained in dense area of cytoplasm close to nucleus (centrosome), involved in cell division

Non-membrane bound, groups of cilia produce wave-like motion across surface of cell, made of microtubules, move organisms, move within organisms

Non-membrane bound, maintains cells shape, intracellular movement, actin filaments (microfilaments), intermediate filaments, microtubules

Non-membrane bound, made up of cytosol (fluid of salts, ions, water) & organelles, where many chemical reactions occur

Non-membrane bound, propel cells through environment, made of microtubules, not hollow

Non-membrane bound, propel cell through environment, made of flagellin proteins, hollow

Non-membrane bound, extracellular region of cell, embedded in within cell membrane, made of carbohydrates (glycoproteins), sticky and viscous, adhesion and cell recognition,

Non-membrane bound, circular DNA, region where DNA is stored in bacterial cells (prokaryotic)

Non-membrane bound, surface of cell & only on bacterial cells, few pili (longer, morge rigid, pillin, DNA transfer) and lots of fimbrae (shorter,less rigid, fimbrillin, attachement),

Non-membrane bound, bacterial cells, circular DNA molecules, "extragenomic" (not part of bacterial genome), integrate with host genome and are passed between bacterial cells via pili

Non-membrane bound, creates gaps to connect plant cells, endoplasmatic reticulum is continuous between cells

Non-membrane bound, micromachine to synthesize proteins, made of proteins and nucleic acid (rNA), free in cytoplasm or bound to ER to form RER

Molecule diffuse across the lipid bilayer or through channel proteins in direction of concentration gradient

Intrinsic proteins let molecules pass through membrane in the direction of concentration gradient

Respond to specific stimulus (ligand)
