Hello dearie !
_____________________________________________________________
Mitochondria
Mitochondria are membrane bound organelles , essential for aerobic respiration of eukaryotic cells . these are also known as power house of the cell . They produces cellular energy in the form of ATP .
Occurrence
Mitochondria are present in all living cells except , prokaryotic cells and certain eukaryotic cells such as anaerobic cells and mature RBCs
It is revealed that mitochondria is not easily visible unless specific stained
Shape and size
mitochondria vary considerably according to shape and size . they have varying in shape such as granular fibrillary , aspherical , oval , discodial , etc.
average size of mitochondria is 2-6 μm in length and 0.5μm in diameter
Ultrastructure :
it contains two membranes i.e. inner and outer membrane
outer membrane is smooth and have a continuous boundry
the inner membrane to semi permeable to some metabolites . it infolded into the matrix as incomplete partitions called cristae
The cristae are responsible for increasing the physiological active area or surface area . the density of the cristae determines the intensity of respiration .
Functions :
I) Mitochondria provide important intermediates for the synthesis of several biochemical like pyrimidines , alkaloids etc.
ii) the inner matrix of the mitochondria has enzyme for the synthesis of fatty acids
iii) helps in regulation of cellular metabolism
iv) helps in apoptosis
v) each of membrane potential

Why they are semi autonomous ?
They are called semi autonomous as they can synthesis some of the proteins as they have cellular DNA not all type .

Hey there!
Mitochondria is a semi autonomous body because:
<> Mitochondria have DNA of their own by which they can reproduce freely.
<> It also have their own ribosomes (i.e mitoribosomes).
<> They synthsize and make protein by their own within the cell nucleus.
<> They show internal growth.
Hope It Helps You!
