Answer 1

a)it regulates the entry of certain ions.
b)cell is the functional and structural unit of every living organism.
c)the contain the green pigment chlorophyll which imparts the color  to flowers and fruits.
d)it protein synthesis to the cell.
e)it regulates cell functions and contain chromosomes.
f) it breakdown of very long chain fatty acids through beta-oxidation.

Answer 2

Plasma membrane-
It is also known as the cell membrane. It is selectively permeable, meaning it only allows certain substances to pass through it.

Cell-
It is the central and structural unit of a living organism. Cells are like bricks of a building. They come from pre-existing cells. They contain several organelles such as Endoplastic Reticulum, Golgi Bodies, Mitochondria, Ribosomes, Lysosomes etc.

Chloroplast-
It is present only in plants. It contains clorophyll that helps the plant in carrying out the process of photosynthesis.

Ribosomes-
Thay are the source of protein synthhesis. When Ribosomes are stuck to the ER, then they are said to be rough Endoplastic Reticulum.

Nucleus-
It is the central organelle of a cell. It contains thread-like genes that helps in transferring the heriditary characters from the parent to the off-spring.

Peroxisomes-
They help in detoxification. Mostly present in the cells of kidneys.

Hope this helps u....☺️☺️
