Membranes can be found in all of the following EXCEPT . A Option A: a ribosome B Option B: a mitochondrion C Option C: a nucleus D Option D: a chloroplast

The correct answer is A. ribosomes

Explanation:

Eukaryotic cell contains both membranous and non-membranous organelles. The membranous organelles are the nucleus, endoplasmic reticulum, Golgi apparatus, chloroplast(plants), mitochondria, lysosomes, etc.

Ribosomes, centrosomes are the non-membranous structures. Ribosomes are found in both eukaryotic and prokaryotic cells. In prokaryotes 70s ribosomes are present and in eukaryotes 80s ribosomes are present. Prokaryotes do not have a membrane-bound nucleus and organelles.

Ribosomes helps in protein synthesis in both prokaryotes and eukaryotes. Therefore the right answer is the ribosome.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

the match lol
