Transcript
Complete the following table to fully describe the various organelles Cell Structure Location Function Cell Membrane External boundary of the cell Confines cell contents; regulates entry and exit of materials Lysosome Throughout cytoplasm To digest invading cells or to break down old organelles Mitochondria Scattered throughout cell Controls release of energy from foods; forms ATP Golgi apparatus Within cytoplasm To process lipids and proteins and ‘package’ them for exocytosis Centrioles Two rod-shaped bodies near the nucleus ‘Spin’ the mitotic spindle Smooth ER Within cytoplasm Synthesises lipids Nuclear pores Within the nuclear membrane To allow mRNA to move into the cytoplasm Rough ER Flattened membraneous sacs located near the nucleus Synthesies proteins Ribosomes Attached to membranes or scattered in the cytoplasm Synthesise proteins Cilia Hair like structures on the surface of some animal cells Act collectively to move substances across the cell surface in one direction Microtubules Throughout cytoplasm; part of cytoskeleton Contractile protein (actin); moves cell or cell parts; core of microvilli Nucleolus Within the nucleus Involved in the synthesis of ribosomes Nucleus Large body situated towards the centre of the cell.
