Which structure or organelle is found in both prokaryotic and eukaryotic cells? A) ribosomes
B) chloroplasts
C) mitochondria
D) endoplasmic reticulum

Answers

Answer: Ribosomes

Explanation:

Eukaryotic cells contain membrane-bound organelles, for example animal cells and plant cells. While prokaryotic cells don't, for example bacteria.

Since chloroplasts, mitochondria and endoplasmic reticulum are membrane-bound organelles, which meas that these organelles are surrounded by a phospholipid bilayer, they are only found in eukaryotes.  

Endoplasmic reticulum is responsible for protein folding, modification and transport. Chloroplast is responsible for photosynthesis in plants, and mitochondria is responsible for cellular respiration. And, ribosomes is the organelle where protein synthesis takes place, and this happens in both Eukaryotic and Prokaryotic cells.
The ribosomes are found in both the prokaryotic and eukaryotic cell.

Which of the following is a not component of lipids?carbon chains
nucleotides
fatty acids
glycerol

Answers

Nucleotides are not a component of lipids.

WHAT ARE LIPIDS:

  • Lipids are one of the four biomolecules we have in nature. Structurally, lipids are made up of monomers called FATTY ACIDS and GLYCEROL.

  • Each of these monomers are made up of long chains of carbon, meaning that lipids also have long chains of carbon.

However, nucleotides are monomers of another biological molecule called nucleic acids and hence, cannot be a component of lipids.
