what is the function of the nucleous
membrane bound ogranelle that contains the cells chromosomes
largest structure in the nucleous of eukaryotic cells
organelle concerned with the synthesis of proteins
controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
what is a ribosome ?
membrane-bound cell organelle that contains digestive enzymes break down excess or worn out cell parts
organelle concerned with the synethesis of proteins
memebrane organelle that contains digestive enzymes break down excess or worn out organelle
subunit of a cell found in both plants and animals
what is golgi apparatus
a small sppherical organelle producing and breaking peroxide

subunit of a cell found in both plants and animals
contractile vacuole ?
used to pump excess water from plant cells
power house of the cell
plastids containing green pigment chlorophyll
what is the function of the plasma membrane
organelles that carry out cellular respiration in eukaryotic cells
regulates substances allowed to enter or leave cells uses embeded proteins
protects and supports plants
the process of manufacturing proteins
what is the function of the cell wall
the process of manufacturing proteins
regulates substances allowed to enter or leave cells
protects and provides skeltetal support that helps keep plant upright
large network of proteins and molecules that surrounded,support and give structure to cells and tissues in body
what is the matrix?
a type of goverment

what is the diffrence between chromatin and chromosomes
all of the above
chromosomes are structures made up of nuceic acids (Carries genetic info)
Chromatin is the substances inside chromosomes
chromosomes are the squiggly things that make up chromatins
chromatins are structures made up of nuceic acids (Carries genetic info)
Chromosomes are the substances inside chromosomes
what is the diffrence between free and bound ribosomes
bound- protiens that are used within the cell while free cells produce stuff that leaves the cell
bound-proteins that leave celll and a free cell produce proteins to use inside cell
