Answer 1

Answer 1

The Human nerve cells perform lots of function, some are :

• Nerve cell transfers and receives messages from brain to body.

• Nerve cells helping to control and coordination the working off different parts of our body.

Answer 2

• Cytoplasm : is the jelly like substance present between the cell membrane and the nucleus. It contains various other components or organelles of cell. They are Golgi bodies, ribosomes, etc.

Answer 3

• Different between both are :

$\tiny \boxed{\begin{array}{c | c } \underline{\bf \: \: \: \: \: \: \: \: \: \: \: \: Plant \: cell \: \: \: \: \: \: \: \: \: \: \: \: \: } & \underline{\bf \: \: \: \: \: \: \: \: \: \: \: \: \: Animal \: cell \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\ \\ \underline{\tiny \sf \: a \: plant \: cell \: have \: a \: cell \: wall.\: \: } & \underline{ \tiny \sf\: a \: animal \: cell \:doesnt \: have \: a \: cell \: wall.} \\ \\ {\tiny \sf \: a \: photosynthetic \: plant \: cell\: \: } & { \tiny \sf\: a \: animal \: cell \:doesnt \: } \\ \underline{\tiny \sf \: \: \: \: \: has\: chloroplast \: in \: it. \: \: \: \: \: } & \underline{ \tiny \sf\: \: \: \: \: \: \: \: have \: any \: chloroplast \: in \: it \: \: \: \: \: } \\ \\{\tiny \sf \: a \: plant \: cell\: \: } & { \tiny \sf\: a \: animal\: cell \:has \: usually \: no\: } \\ {\tiny \sf \: \: \: \: \: has\: a \: large \: vacuole \: in \: it. \: \: \: \: \: } & { \tiny \sf\: \: \: \: vacuole \: only \: some \: have \: but \: small.\: \: } \\ \\ \end{array}}$

Did you know :

• Our skins outermost layer contains dead cell. An average adult carries around about 2 kg of dead skin. Billions of tiny fragments of the skin are lost every day, every time you run.

• Amoeba is so lucky for the power of changing its shape because it helps in moving and capturing foods.

• Elephant looks large than a rat but their size of cells are same in size, shape and types.

• Robert Hooke discover cell.

• Cells are same as like as brick, bricks join to make a house, on the other hand cells join to make a body.
