Answers
1.GOLGI BODY/GOLGI APPARATUS- It is made of several membrane bound,fluid-filled,sacs.which are stacked together.it is responsible for the packaging and transporting of fats, proteins.It also helps in formation of lysosomes.
2.VACUOLE-Vacuoles store excess water,useful minerals,pigments and many other substances.Large vacuoles are present in plant cell.
3.LYSOSOMES-Lysosomes contain chemical substance called enzymes that are capable of digesting cells and a variety of intra and extra cellular materials.in times of emergency lysosomes burst and destroy the cells.hence they are called suicide bags of the cells.
4. ENDOPLASMIC RETICULUM- it is involved the synthesis,storage and transport of cell products.
5.RIBOSOMES-They are primary sites of protein synthesis
6.MITOCHONDRIA-They act as sites of energy production and are therefore called power houses of the cell.
7.PLASTIDS-Depending on the pigment color plastids are of three kind
i)chloroplasts contain green pigment chlorophyll which helps plants in making food
ii)chromoplasts contains non green pigment that give color to fruits and flowers.
iii)Leucoplasts are colorless and store food in the form carbohydrates fats and proteins
8.CENTROSOMES-They are present only in animal cells. Centrosomes initiates and regulates cell division.
