Question

Explan cytoplasm ,, mitrochondria ,, plastids ...


No small Answer required

Answer 1

above is the pic of the above topic.

one more thing is mitochondria was discovered by E. Colicher.

Answer 2

$\huge\bold{Answer}$

$\boxed{\textbf{Cytoplasm}}$

It is viscous opaque substance . it is present between nucleus membrane and cell membrane. in a living cell many types of organelles of different size and shape are found. it contain many insoluble granular of storage substance. there are also present organic compound like carbohydrates, protein ,liquid , enzymes and inorganic compound like water and salt.

$\underline\bold{Function}$
cytoplasm provide chemical site and environment from different biochemical reaction.

$\boxed{\textbf{Mitochondria}}$

they are oval or Rod like structure . their membrane is doubled outer membrane is smooth while inner membrane has enfolding in the microchondrial matrix . there in there en folding called cristae .

there are about 1 million elementary particle in one microchondrion they are strange in having their own DNA and ribosomes for making some of their own protein themselves.

$\underline\bold{Function}$
micro chondria are very important organelles of Eukaryotic cell the process of breaking down of food take place in micro Chunariya which result in production of unit of energy called ATP this energy is used by cells in various function therefore micro chondria are also called powerhouse of the cell .

$\boxed{\textbf{Plastids}}$ These are pigment containing organelles these are found in plant cells many plastid have one or more than one pigment


Plastids are of three types which are follows


Chloroplast=> these are the most important plastids these are green in colour and found in green parts of plant these contains chlorophyll which helps in photosynthesis the study of ultrastructure reveals that it is bounded by double membrane.

they also have their own DNA and ribosomes and also known as semi - autonomous bodies

$\underline\bold{Function}$ in chloroplast photosynthesis take place and food is prepared by plants.

Chromoplasts =>these are second type of plastids there are of various colour other than green in plant colours other than green are due to chromoplast these are present in the petals of the flower and in the ripened fruit .

$\underline\bold{Function}$
these help the plant in pollination these impart various colours to Petals and fruits.

Leucoplasts =>these are third type of plastids these are colourless plastids .These are triangular tubular all of any other shape.

$\underline\bold{Function}$ these are found in food storage part of plant especially in roots
