Question

A cell has mitochondria, ribosomes, smooth and rough ER, and other

parts. Based on this information, it could not be
(a) A cell from a pine tree. (b) A grasshopper cell.
(c) A human cheek cell. (d) A bacterium.
Justify your answer.

Answer 1

The answer is d. A bacterium

Bacterium are made of a prokaryotic cell, which does not contain cell organelle.

I noticed another answer claimed that pine tree cell could also be a correct answer, this is not true as pine tree cells are eukaryotic. Both plant and animal cells contain the organelles listed here, therefore a pine tree cell is possible.

A grasshopper and human cheek both contain eukaryotic animal cells, and are therefore also possible origins for the cell in question.

Hope this helps

Answer 2

(b) a grasshopper cell and (c) a human cheek cell are possible candidates.

Step-by-step explanation:

The presence of mitochondria, ribosomes, smooth and rough ER, and other parts indicates that the cell in question is a eukaryotic cell. Therefore, option (d) a bacterium can be ruled out as bacteria are prokaryotic cells and lack membrane-bound organelles like mitochondria and endoplasmic reticulum.

Option (a) a cell from a pine tree can also be ruled out because although pine tree cells are eukaryotic, they lack many of the organelles found in animal cells, including mitochondria and a well-developed endoplasmic reticulum.

Option (b) a grasshopper cell is a eukaryotic cell and contains the organelles mentioned, making it a possible candidate.

Option (c) a human cheek cell is also a eukaryotic cell and contains the organelles mentioned, making it a possible candidate.

Therefore, based on the given information, it could not be (a) a cell from a pine tree, and option (d) a bacterium can be ruled out.
