Inner membrane of the chloroplasts
Explanation:
The present day eukayrotes are all considered to be derived from its original ancestor – the cyanobacteria.
Earlier, photosynthesis by the first photoautotrophs took place utilizing hydrogen sulphide as the electron donor. However, it was later when the cyanobacteria, which were originally residing in the mitochondria of an eukaryotic cell under an endosymbiotic relationship, developed into true chloroplasts, the use of water as electron donor to perform photosynthesis began.
The cyanobacteria were aerobic in nature and required oxygen to survive. They evolved the chloroplasts covered with an external protective membrane and an internal membrane. It is the internal membrane which contains all the necessary organelles or components necessary for photosynthesis like thyllakoids, stroma etc which helped them to utilize water as an electron donor during photosynthesis like all the eukaryotes.
Answer:
They have genetic material.
Explanation:
All three domains and viruses have genetic material. They have to, otherwise they couldn't reproduce, whether sexual or asexual. In viruses, it can be RNA or DNA; obviously in eukarya it tends to be DNA, remembering that humans are eukaryotes; and in the other two domains a similar pattern is followed.
Why not the other options?
They are composed of cells
- Viruses technically don't have "cells," and even to say cells plural can be a misnomer for some of the more simple forms of life that are unicellular.
They are living things.
- All three domains are alive (bacteria, archaea, eukarya) but viruses are technically not considered to be alive.
They have organelles.
- Eukarya and prokarya technically both have organelles (think of prokaryotic ribosomes), but not all groups that you mentioned have organelles. Remember that organelles ("little organs") are specific groups of cells performing a function, and they usually have names.
Answer: DNA is found in every cell of our body– except red blood cells (no nucleus). Genes are a segment of DNA. Our genes are the blueprint for our biology.
Explanation:
The answer might be cytoplasm
