    Which statement is false?
    a. The pH of the cytosol is more acidic than the lysosome
    b. Lysosomes are found in both plant and animal cells
    c. Macrophages are differentiated from monocytes
    d. Macrophages are rich in lysosomes
    e. All are correct

    The answer says A. I agree, but isn't B also false. Plant cells lack lysosomes. They have vacuoles which perform similar processes. My cliffs AP Biology says plant cells lack Lysosomes. I have also found numerous sources on the internet saying plant cells lack Lysosomes.

    Help Please

    This was mentioned somewhere else on this site. I believe the central vacuole of plants does same functions as animal lysosomes but they also have lysosomes themselves. HOpefully Dr. Romano or Nancy comes and clears this up.

    Usually plant cells do not have lysosomes. However, there is growing evidence that some plant cells have lysosomes or lysosome-like structures. It is rare, but it was reported. That is why B is not completely false. I have actually read several papers on plant lysosomes. Feel free to google it, it will make for a good read.

    Hope this helps.

    Thank you. I guess Cliffs AP Bio might be getting a little outdated
