Cell quiz
mitchondria
the powerhouse of the cell, produces energy from food
ribosome
manufacures proteins which are important for cell and organism function
vacuole
storage centers for water, food, wastes and other materials
gogli body
this organells packages materials for transport outside of the cell
cytoplasm
substance that fills the interior of the cell. it is a jelly like material that supports the nucleus and other organells
cytoskeleton
provides support and structurw
er
aid in transport of materials around the cell two types rough and smooth
nucleolos
makes ribosome makes up nucleus
nucleus
control center of the cell coordinates controls and manages all cell functions storage center for all info
lysosome
small membrane bound poches that countain digestive enzymes enzymes break down food and digest wasts
cellwall
it protects the interior of the cell and gives the cell a regular shape and allows support so plant can stay upright
chloriplasts
contain chlorophylland allow plant cells to make their own food through photosynthesis
mitosis
the process of dividing the nuclear membrane material and ending with cell division all new cells are formed this way and are identical
interphase
majority of a cells life is soent in this phase, the cell grows, replicates its DNA and prepares for the next divison cycle. the chromatin is in a relaxed stete inside nucleus. before cell divides the chromatin condense into chromosones.
Prophase
chromatin completes condensing into chromosomes. nucleolus and nuclear membrane dissapear. spindle fibres form and stretch from organells called centrioles they attach to chromosomes
Metaphase
spindle fibres pull the double-stendered chromosomes inti a line across the middle of the cell
anaphase
spindle fibers contract and shorten pulling the centromeres apart. the chromatids seperate from each other they are now referred to as chromosomes
telophase
one complete set of chromosomes is now at each poleof the cell. spindle fibers disappear, nuclear menbrane forms around DNA. Chromosomesbegin to uncoil back into chromatin. still one cell at this point hut the cell begins to elongate
cytokinesis
end of telophase. This is the actual process of cell divsion. new cells are called daughter cells. animal cells membrane pinches in the middle. called a cleavage furrow. plant cells a cell plage forms between the two nuclei
