|
cell wall
|
rigid layer of nonliving material, only in plant cells, protects the cell, tough, many materials can pass through
|
|
|
cell membrane
|
located just inside the cell wall. present in all cells. controls what flows in and out of the cell. lets food, oxygen inand harmful waste out.
|
|
|
nuclear envelope
|
around the nucleus. protects the nucleus.
|
|
|
chromatin
|
thin strands floating directly ahead in the nucleus. knows how to direct the cell.
|
|
|
nucleolus
|
makes ribosomes. inside the nucleus.
|
|
|
mitocondria
|
rod-shaped structure. pwoerhouses of the cell. converts energy in food molecules into energy
|
|
|
endoplasmic reticulum
|
maze of passageways. the passageways carry proteins from one part to the other part of the cell

|
ribosomes
|
attached to some surfaces of the ER. float in cytoplasm. small, grainlike bodies. produce proteins. proteins move to the golgi body

|
|
golgi body

flattenedsacs and tubes. cell's mail room. receives protein and distribues them throughout the cell.
|
|
|
chloroplast
|
large green structures floating in the cytoplasm. only in plant cells. photosynthesis. makes leaves green
|
|
|
vacuoles

|
|
lysosomes
|
small, round structures containing chemicals that break down certain materials in the cell. cleanup crew in the cell
|
|
|
organelle
|
tiny cell structures. example: cell wall, cell membrane, chloroplast
