| Question | Answer |
|---|---|
| lysosomes | contain digestive enzymes; plant and animal |
| Cell membrane | also called plasma membrane;lipid bilayer;surrounds entire cell;composed of lipids and protiends;selectively permeable; plant and animal |
| cytoplasm | fluid-like material that holds organelles inside the cell;location of many chemical reactins; plant and animal |
| nucleus | "brain of the cell";large and round;contains chromosomes and DNA;directs chemical activities of t he cell;surrounded by nuclear membrane; plant a nd animal |
| nucleolus | inside the nucleus;make RNA for ribosomes |
| ribosome | small bumps on the rough ER; high quantity;may float freely; plant and animal |
| Endoplasmic Reticulum | series of canals; intracellular transport; smooth or rough; plant and animal |
| Mitochondria | "powerhouse of the cell"; site of aerobic respiration; produces ATP; plant and animal |
| Golgi Apparatus | Membrane-bound channel which PACKAGE AND STORE materials |
| vacuoles | spaces in the cytoplasm enclosed by a membrane; 3 types, food -work with lysosomes,contractile-pumps out excess HOH,storage-stores chemicals;plants have one big one;animal cells have many small ones |
| centrioles | pair of cylindrical structure found just outside the nuclear membrane of animal cell only! |
| Cell Wall | STRUCTURE and RIGIDITY;completely permeable,non-living; plant cells only |
| Chloroplasts | Contains Chlorophyll-pigment needed for photosyntesis; Only in Plant Cells |
