Golgi apparatus (c) Mitochondria
Answers
Answer:
HEY MATE
HERE'S UR ANSWER ..
FUNCTIONS OF THE FOLLOWING ORGANELLES :-
Nucleus :-
It controls all the metabolic activities in the cell and contains genetic information in the form of genes.
It regulates cell cycle adnd cell division.
It controls the growth in cell by governing the synthesis of structural proteins.
Mitochondria :-
Mitochondria are the sites of aerobic respiration called. Kern's cycle.Here,the food is oxidised by the use of molecular oxygen and energy is released in the form of ATP.
They provide intermediates for the synthesis of various biochemicals like steroids , fatty acids , chlorophyll and amino acids.
Golgi Apparatus :-
It helps in the secretion of mucus , enzymes and hormones by the formation of secretory vesicles ad vacuoles.
It helps in synthesis of cell wall plasma membrane and lysosome.
It helps in formation of complex sugars from simple sugars.
It helps in storing , modifying and packaging the material coming from endoplasmic reticulum.
Chloroplast :-
Chloroplasts traps the solar energy and transforms it into the chemical engery .
Lysosomes :-
It helps to remove the cell debris ,dead and worn out cell organelles.
It digest stored food contents like protein and fat in a controlled manner during starvation and provides necessary engery.
The lysosomes destroy the foreign particles ( pathogens).
Vacuoles :-
It helps the plant cell to remain turgid and rigid.
It maintains osmotic pressure in the cell.
It helps in the storage of sugar, amino acids , organic acids and proteins.
It helps in the digestion and excretion in lower organisms.
