Answer:

Explanation:

(1) PLASMA MEMBRANE MADE UP OF LIPID BILAYER AND PROTEIN MOLECULES EMBEDDED IN IT { BOTH INTRINSIC AND EXTRINSIC PROTEINS]

(2) A SOLUTION WHICH POSSES MORE AMOUNT OF SOLVENT [ LIQUID PART ] AS THAT COMPARED WITH THE AMOUNT OF SOLUTE[ SOLID PART ] IS CALLED HYPOTONIC SOLUTION.

(3) CELL WALL OF PLANT CELLS ARE  MADE UP OF CELLULOSE.

(4) AMOEBA , PARAMOECIUM.

(5) WHEN A CELL IS PLACED IN A HYPERTONIC SOLUTION[ SOLUTION IN WHICH THE SOLUTE PART IS MORE AS COMPARED WITH THAT OF SOLVENT PART] DUE TO THE CONCENTRATION GRADIENT ,AS THE CELL CONTAINS MORE SOLVENT THAN THE SOLUTION, SOLVENT FROM THE CELL MOVES OUT INTO THE EXTERNAL MEDIUM [EXOSMOSIS TAKES PLACE ]AND THE CELL GETS SHRINKED.

THIS PHENOMENON IS CALLED PLASMOLYSIS.

(6) CHROMOSOMES ARE PRESENT INSIDE THE NUCLEUS OF THE CELL

IT CONSIST OF DNA, RNA , HISTONE AND NON HISTONE PROTIENS.

(7) FIRST LIVING CELL DISCOVERED BY :LEEUVENHOEK

   FIRST DEAD CELL DISCOVERED BY : ROBERT HOOEK[ FIRST DISCOVERY]

(8) ROBERT BROWN (1831)

(9) RUDOLF VIRCHOW [ CELL THEORY :1855]

(10) TAKING IN MATTER BY A LIVING CELL BY INVAGINATION OF ITS MEMBRANE IS CALLED ENDOCYTOSIS.

HOPE THIS HELPS.
