STUCTURE AND FUNCTION OF ORGANELLE
NUCLEUS
>Sphere or oval
>Double membrane organelle
>Carry genetic information
>Direct protein synthesis
>Consist nuclear envelope,nuclelous and chromatin
Nuclear envelope:>Double membrane separate nuclear content
from surrounding cytoplasm
from surrounding cytoplasm
Nucleoplasm:>Interior part of nucleus with full of chromatin
Nuclelous:>A mass of densely stained granules and fibres
adjoining part of chromatin
adjoining part of chromatin
>Spherical in shape
>Non membranous
>Function:Produce rRNA,form ribosome
ENDOPLASMIC RETICULUM
>Network of membranous sacs and tubes
>Continues with nuclear envelope
Smooth ER:>Has lack of ribosome on its outer surface
>Synthesis of lipid
>Metabolism of carbohydrate
>Detoxification of drugs and poison
>Storage of calcium ions
Rough ER :>Studded with numerous Ribosome
>Process and transport protein synthesizes by ribosomes
GOLGI BODY
>Consist of flattened memmranous sacs
>Function:Modifies processes or store the substance
Cis Face:>Located near the ER to transport vesicle from ER to Golgi Body
>Recive vesicle containing ER products from transport vesicles
Trans Face:>packages molecules in vesicles and transport them out of Golgi Body
LYSOSOME
>Spherical sacs
>Surrounded by single membrane
>Contining hydrolytic enzyme
>Function:Intercellular digestion such as Phagocytosis and Autophagy
Phagocytosis:>digesting food particle by engulfing
Autophagy:> digesting damage organelle
RIBOSOME
>Small granule
>Consist of two subunit which is small and large
>Non membranous
>Manufactured in nuclelous of nucleus
>Function:The site of protein synthesis.
Responsible for then formation of peptide bond
MITOCHONDRIA
>Double membrane
>Outer membrane:smooth
Inner membrane: convulated with enfolding called cristae
>Function:Site of cellular respiration
Cristae:>increase large surface are to make gaseous exchange more efficient
CHLOROPLAST
>Double membrane
>Contain chlorophyll
>Contain its own DNA and Ribosome
>Function:Site of photosynthesis
>Thylakoid:combination of grana(light reaction occurs)
>Stroma(dark reaction occurs)
>Integranal Lamella:connented thylakoid of adjacent grana
CENTROSOME AND CENTRIOLE
Centosome:region usually located near the nucleus
Centriole:A pair of short microtubules each composed of nine sets of triplets
microtubules arranged in a ring
>Function:Microtubule organizing centre and and important in cell division of animal cells.
Initiate the spindle that organizes and separates the chromosomes
VACOULE
>Single membrane
>Membrane bound sacs containing water or dilute solution of salts and other solute
called Cell Sap
>Function:> structural support
>storage for nutrient
>waste disposal
>protection
>growth
