Nuclear Envelope
Location: around the nucleus
Function: controls what gets into the nucleus
Structure: double membrane, lots of pores
Function: controls what gets into the nucleus
Structure: double membrane, lots of pores
Nucleolus
Location: inside the nucleus
Function: makes ribosomal subunits from proteins and ribosomal RNA, then sends the subunits out to the rest of the cell where they combine into complete ribosomes.
Structure: non-membraned, filled with proteins and nucleic acids
Function: makes ribosomal subunits from proteins and ribosomal RNA, then sends the subunits out to the rest of the cell where they combine into complete ribosomes.
Structure: non-membraned, filled with proteins and nucleic acids
Nucleus
Location: dark spot anywhere in the cytoplasm (eukaryotic)
Function: controls everthing, brain-like
Structure: nuclear envelope, double membrane
Function: controls everthing, brain-like
Structure: nuclear envelope, double membrane
Peroxisomes
Location: all around cytoplasm
Function: digesting toxic objects like hydrogen peroxide and fatty acids
Structure: single membrane, filled wth enzymes
Function: digesting toxic objects like hydrogen peroxide and fatty acids
Structure: single membrane, filled wth enzymes
Ribosomes
Location: (prokaryotes and eukaryotes) in many places llike: membrane, endoplasmic reticulum,
Function: protein builders,
Structure: have RNA and polypeptides and formed into bacteria and archaea
Function: protein builders,
Structure: have RNA and polypeptides and formed into bacteria and archaea
Rough Endoplasmic Reticulum
Location: near nucleus and Golgi apparatus (plant and animal cells)
Function: make proteins exported from the cell, or into the cell membrane
Structure: looks like piled up paper, covered with dots (ribosomes) that give it a rough look
Function: make proteins exported from the cell, or into the cell membrane
Structure: looks like piled up paper, covered with dots (ribosomes) that give it a rough look
Smooth Ednoplasmic Reticulum
Location: near nucleus and Golgi apparatus (plant and animal cells)
Function: blending of steroids in gland clells, checking of calcium in muscle cells, breaking down of toxic in liver cells
Structure: not covered with dots, smooth looking
Function: blending of steroids in gland clells, checking of calcium in muscle cells, breaking down of toxic in liver cells
Structure: not covered with dots, smooth looking
Vacuole
Location: so large pushes all the other organelles towads the cell membrane, mostly middle of cell
Function: store enzymes and metabolic wastes
Structure: fluid-filled, large 90% of plants volume,
