Answer 1

heya !!

>answer 1 :● plastids are double membrane bound cell organelles which contain their own pigment and food and found in cytoplasm of the cell.
●Plastids are the site of manufacture and storage of important chemical compounds used by the cell.

>answer 2 :plasma membrane is made up of lipoproteins or Phospholipids (Phospholipids are lipids with a phosphate group attached to them. )

>answer 3 :in the thin slices of cork cell , robert hooke first observed pores or cells.also ,he viewed cell wall in cork tissue.

>answer 4 :the autonomous organelles in the cell are  Mitochondria and chloroplasts . It is because they have their own DNA, mRNA, tRNA & ribosomes and can reproduce independently.

>answer 5 :the total living part of a cell , which includes cytoplasm, nucleus and other cell organelles is known as protoplasm.
