Cell structure, function, and organization Flashcards
what is a cells 3 main parts
Plasma membrane
Cytoplasm
Nucleus
Organelles function
carry out metabolic functions necessary to maintain the cell.. Also called cellular functions.
Smooth endoplasmic reticulum function
site of lipid production and storage
rough endoplasmic reticulum function
a cell organelle containing ribosomes that synthesizes and processes proteins in the cell
Golgi apparatus function
where protein vesicles are modified, packaged, and transported to where they are needed. Golgi often referred to as the manufacturing and shipping department of the cell. also responsible for packing digestive enzymes within vesicles known as lysosomes
Lysosomes function
Break down polymers. Necessary for cellular metabolism
Mitochondria function
organelle changes food energy into usable cellular energy via the process known as cellular respiration. usable energy is adenosine triphosphate ATP
In mitosis, one cell reproduces
into two genetically identical daughter cells
Events of mitosis
interphase
prophase
metaphase
anaphase
telophase
interphase
DNA replicates
prophase
chromosomes condense, and visible chromosomes appear
Metaphase
chromosomes align
anaphase
chromosomes are pulled apart to the poles. Cell division begins
telophase
two nuclei form. daughter cells separate
Meiosis events
interphase
Meiosis I
prophase I
metaphase I
anaphase I
telophase I
Meiosis II
prophase II
metaphase II
anaphase II
telophase II
