Question

1. Who discovered cells and how ?

2. why is the plasma membrane called a selectively permeable membrane?

3. why are lysosomes know as suicide bag?



​

Answer 1

Explanation:

in 1665, Robert Hooke discovered cells while examining a thin slice of cork through a self-designed microscope. He observed that the cork resembled the structure of a honeycomb consisting of numerous tiny compartments. The minuscule boxes are referred to as cells.

A cell or plasma membrane is called "selectively permeable" because it is selective about what it allows to pass through it.

Answer 2

Answer:

Hey mate here is ur answer...

Explanation:

1) Robert Hooke

2) The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. ... If plasma membrane ruptures or breaks down then molecules of some substances will freely move in and out of the cells.

3) Lysosomes are known as suicide bags of the cell because they contain lytic enzymes capable of digesting cells and unwanted materials. When lysosomes burst, the lytic enzymes within the organelle spill all over the cell, rupturing the cell membrane or cell wall and inducing the death of the cell.
