Describe the structure and function of the following:-Nucleus,Mitochondria,Golgi bodies,E.R.,Ribosomes.?

NUCLEUS
structure: contain nuclear evelope, nucleoplam, nucleolus
function: essential for cell division, controls cell activities such as cell growth and repairing of worn-out parts

MITOCHONDRIA
structure: sausage-shaped
function: during aerobic respirattion, enzymes from mitochondria oxidises food substances to release energy

GOLGI APPARATUS
structure: stack of flatenned spaces enclosed by membranes
function: stores and modifies proteins made by the ER, packed modified substances into vesicles for secretion out of the cell

RIBOSOMES
structure: i don't no sorry!
function: there are 2 depending on whether the ribosomes are attached to the rough endoplasmic reticulum or situated at the cytoplasm

at cytoplasm: make proteins for use within cells
at RER: make proteins for secretion out of the cell

(=

Nucleus:
Structure: it contains 1 nuclear envelope ( gateway to the nucleus) 2 Chromosomes ( genetic containers) 3 nucleolus ( preassembly point for ribosomes)
Function:it directs the chemical reactions in cells by transcribing genetic information from DNA into RNA. nucleus also stores genetic information & transfers it during cell division from one cell to the next.it Controlss cell's genetic program & metabolic activities.
Mitochondriaia:
Structure: double membrane bound organelles that are spherical to elongate in shape.
Function:converts energy into a from the cell can use.
Golgi bodies:
Structure: it is collection of membranes associated physically & functionally with the E.R  in the cytoplasm. it is composed flattened stacks of membrane-bound cisternae.
Function:sorts, packages and routes cell's synthesized products.
Endoplasmic Reticulum:
Structure: extensive membrane system extending throughout the cytoplasm from the plasma membrane to the nuclear envelope.
Function:storage & internal transport.rough E.R is a site for attachment of ribosomes; smooth E.R makes lipidsRibosomeses:
Structure: non-membrane-bound structures,contain almost equally amounts proteinein & a special type of ribonucleic acid called ribosomal RNA.
Function: it is site fproteinein synthesis.
