Answer» vacuole endocytosis chromosome contains genetic material called gene which help in transfer of inheritance characteristics from parents to offsprings Adenosene Tri phosphate. It is produced in the mitochondria. a) nucleoid b) mitochondria endoplasmic reticulum is a CELL organelle. Two types of endoplasmic reticulum are : 1. ROUGH endoplasmic reticulum 2. smooth endoplasmic reticulum it's main functions are : it helps in synthesis of fats and lipids with the help of ribosomes it synthesis proteins and also help in membrane BIOGENESIS. 7 .diffusion = it is a process in which gases moves through a semipermeable membrane from a region of higher concentration to lower concentration. OSMOSIS : it is a process in which water molecules move through a semipermeable membrane through a region of higher concentration to lower concentration. 8. lysosomes helping the elimination of foreign substances entering the cell and destroying the worn out substances in the cell. it is called SUICIDAL bag because when the cell when is cell don't work properly and then the lysosomes burst and and its digestive enzymes destroy its own cell there for it is called suicidal bag. 9. mitochondria. it is able to make its own proteins because it contains its own ribosomes.

Answer»

vacuole
endocytosis
chromosome contains genetic material called gene which help in transfer of inheritance characteristics from parents to offsprings
Adenosene Tri phosphate. It is produced in the mitochondria.
a) nucleoid b) mitochondria
endoplasmic reticulum is a CELL organelle. Two types of endoplasmic reticulum are :

1. ROUGH endoplasmic reticulum

2. smooth endoplasmic reticulum

it's main functions are : it helps in synthesis of fats and lipids with the help of ribosomes it synthesis proteins and also help in membrane BIOGENESIS.

7 .diffusion = it is a process in which gases moves through a semipermeable membrane from a region of higher concentration to lower concentration.

OSMOSIS : it is a process in which water molecules move through a semipermeable membrane through a region of higher concentration to lower concentration.

8. lysosomes helping the elimination of foreign substances entering the cell and destroying the worn out substances in the cell. it is called SUICIDAL bag because when the cell when is cell don't work properly and then the lysosomes burst and and its digestive enzymes destroy its own cell there for it is called suicidal bag.

9. mitochondria. it is able to make its own proteins because it contains its own ribosomes.
