Answers
1 (a)
2 The question should be "The barrier between the protoplasm and the outer environment in an animal cell is. but you have mentioned other
As there is no such barrier inside the cell, the material inside the cell membrane including cytoplasm, nucleoplasm and matrix of organelles constitutes protoplasm. Then its answer will be ( d)
