Ch 3: Cells Flashcards
Cytoplasm function
Suspends all cell structures
Cytosol =
Liquid part of cytoplasm
Cytoskeleton function
Gives cell its shape & assists with movement
Nucleus function
Controls cell activity
Nucleolus function
Holds RNA
Nucleoplasm function
Suspends RNA
Nuclear membrane function
Seperates DNA from cytoplasm
Nuclear pores function
Allows large molecules to pass through
Mitochondria function
Cellular respiration
Golgi body function
Modification, packaging and secretion of proteins
Endoplasmic reticulum function
Storage and transport of materials, surface on which chemical reactions can occur
Centrioles function
Involved with reproduction of the cell
Ribosomes function
Protein synthesis
Lysosomes function
Break down new materials, dispose of old organelles
Organelles are
All the structures suspended writhing the cytoplasmic within call membrane, that carry out particular functions
Vesicles are
Small bubbles of liquid containing proteins, form on edges of the membrane of Golgi body
Inclusions are
Chemical substances that are not part of the cell eg.haemoglobin
Cell membrane function
Semi permeable membrane allows certain substances in/out of the cell, seperate a from external environment
