function of organelles Flashcards
what is the function of nuclear pores ?
transport and movement of mrna nucleotides and rrna
what is the function of smooth endoplasmic reticulum?
synthesis and transport of lipids
what is the function of the nuclear envelope?
protects the cells genetic material from the chemical reactions that take place outside the nucleus
allows mRNA and ribosomes out of the nucleus
what is the function of the plasmodesmata ?
transverse the cell wall and allows to conduct and exchange fluids between various cellular molecules between the plant cells
what is the function of the nucleolus ?
tRNA rRNA and ribosomes produced here
what is the function of chromatin?
compresses dna into a compact unit that can fit into the nucleus
what is the function of the nucleus?
holds dna in the chromosomes and carries the genetic code which codes for polypeptides
what is the function of a vacuole?
supports plant tissues
stores water glucose and amino acids
what is the function of chloroplasts ?
site of photosynthesis
what is the function of centrioles?
involved in cell division
responsible for producing and organising the spindle fibres that control cell division in animals
what is the function of lysosomes?
digest worn out organelles within the cell and foreign material that has been engulfed by phagocytosis
what is the function of the golgi body?
modifies and packages proteins
produces secreting enzymes
producing glycoproteins
forms lysosomes and digestive enzymes
what is the function of ribosomes ?
synthesises proteins
what is the function of rough ER
transports polypeptides to golgi body
what is the function of mitochondria?
mitochondria synthesise ATP during aerobic respiration and produce most of the ATP in a eukaryotic cell
