ব্যাখ্যা
The term
“protoplasm”
refers to the living substance inside a cell, including the cytoplasm and nucleus.
This term was coined by
J. E. Purkinje
in
1839
.
Protoplasm is considered the
physical basis of life
because all vital activities of a cell take place in it.
Dujardin
used the term “sarcode” for the living substance in protozoa, not protoplasm.
Schwann
is known for formulating the cell theory.
Hooke
discovered the cell, not the term protoplasm.
Hence, the term
“protoplasm”
was coined by
Purkinje
.
প্রোটোপ্লাজম
হলো কোষের ভেতরের জীবন্ত পদার্থ, যার মধ্যে সাইটোপ্লাজম ও নিউক্লিয়াস অন্তর্ভুক্ত।
এই শব্দটি প্রবর্তন করেছিলেন
জে. ই. পারকিঞ্জে (Purkinje)
1839
সালে।
প্রোটোপ্লাজমকে
জীবনের ভৌত ভিত্তি
বলা হয়, কারণ কোষের সব গুরুত্বপূর্ণ কার্যাবলি এর মধ্যেই সম্পন্ন হয়।
ডুজার্ডিন
প্রোটোজোয়ার জীবন্ত পদার্থকে “সারকোড” নামে অভিহিত করেছিলেন, প্রোটোপ্লাজম নয়।
শোয়ান
কোষতত্ত্ব প্রণয়নের জন্য পরিচিত।
হুক
কোষ আবিষ্কার করেন, প্রোটোপ্লাজম শব্দটি প্রবর্তন করেননি।
অতএব, ‘প্রোটোপ্লাজম’ শব্দটি প্রবর্তন করেছিলেন
পারকিঞ্জে
