prokaryotic and eukaryotic cells
endosymbiotic theory
is it possible today for a plant leaf cell to live without mitochondria and chloroplasts?
yes, cells can live without mitochondria and chloroplasts. they can be replaced with other organelles.
no, cells cannot live without mitochondria and chloroplasts; they provide the dna the cell needs to survive.
no, cells cannot live without mitochondria and chloroplasts; they provide the energy cells need to survive.

Explanation:

To determine the answer, we analyze the functions of mitochondria and chloroplasts in plant leaf cells. Mitochondria perform cellular respiration to produce ATP (energy), and chloroplasts perform photosynthesis to produce glucose (energy - rich molecules). A plant leaf cell needs energy from both processes. The third option correctly states that cells can't live without mitochondria (for ATP production) and chloroplasts (for glucose production, which is also used in respiration) as they provide the energy cells need to survive. The first option is wrong because these organelles can't be easily replaced, and the second option incorrectly links chloroplasts to DNA provision (they have their own DNA but that's not the main reason for cell survival here).

Answer:

No, cells cannot live without mitochondria and chloroplasts; they provide the energy cells need to survive. (The third option in the given choices)
