cell (plasma membrane) phospholipd bilayer; covers cell; semipermeable (selectively permeable)- allows some molecules to pass in and out
vacuole temporary storage of materials (food, water, enzymes, waste); large in plant cells, but rare in animal cells
cytoplasm clear, gelatinous fluid inside cell (mostly water); fluid that surrounds all of the other organelles
endoplasmic reticulum site of chemical reactions and transport of materials; can be smooth(without ribosomes) or rough(with ribosomes)
lysosome containsdigestive enzymes (suicide sac); digests excess/worn out organelles, food particles, and viruses/bacteria
chloroplast convert light energy to chemical energy (only in plants); contains the green pigment chlorophyll within thylakoid membranes
nucleus control center of the cell; surrounded by a porus membrane; contains strands of DNA celled chromatin; contains nucleolus which makes ribosomes; contains blueprints to make preteins
ribosome site of protein synthesis; passes through nuclear pores and attaches to rough endoplasmic reticulum
cell wall protects cell and gives support; inflexible barrier (only in plants); outer layer composed of cellulose in plant cells
golgi body/apparatus flattened stacks of tubular membranes (pancakes); sorts and packages proteins into vesicles
mitochondria site of cellular respiration; energy produced here; has highly folded inner membrane for higher energy production
