Parts of the Cell cell membrane -forms outer boundary of the cells - semi-permeable – only lets certain things in and out of the cell - made of a layer of phospholipids and some proteins (lipid bilayer) cell wall - provide strength and support - made out of cellulose fibers - only found in plants cells cytoplasm - gel-like fluid - made of water and other chemicals - always moving or circulating around the cell - surrounds all the organelles nucleus - largest (usually) & most visible organelle - stores DNA in chromatin (chromatids) - directs all other activities in the cell (control center) nucleolus - inside the nucleus - stores materials used to make ribosomes ribosomes - most abundant organelle - smallest organelle - make proteins from amino acids (using directions from the nucleus) - can be found in the cytoplasm or on the endoplasmic reticulum endoplasmic reticulum (or E.R.) - folded membrane that moves materials around the cell (like a conveyer belt) - 2 types: rough – has ribosomes on it & smooth – doesn’t have ribosomes on it mitochondria - bean shaped - breaks down food into energy (ATP) - “powerhouse of the cell” - more active cells (muscle cells) have more mitochondria chloroplasts - only in plant cells - insides look like stacks of coins - contains chlorophyll - uses sunlight to make sugar (photosynthesis) Golgi body - stacks of membrane-covered sacs (or Golgi complex or (looks like E.R.) Golgi apparatus) - process and transport materials out of the cell (shipping department) - named for Camillo Golgi (1898) vacuole - membrane-covered chambers - storage areas (like a warehouse) - stores food, water or waste products - larger in plant cells than in animal cells - liquid in vacuoles gives flowers their color lysosome - contain digestive enzymes - break down wastes, worn-out cell parts, & foreign invaders - when a cell dies lysosomes break them down - breaks down tadpoles’ tails when they turn into frogs ..
