Answer:
a It has membrane-bound organelles
b It converts stored energy to use for cellular processes
Explanation:
Prokaryotic cells lack membrane-bound organelles such as a nucleus and mitochondria, that are present in eukaryotic cells. However, they do have a cell membrane that separates the cell from the outer environment.
Prokaryotic cells do not have mitochondria to break down stored material into energy, instead they obtain their energy from light or chemical sources. This is in contrast to eukaryotic cells, which can break down sugars to produce energy.
Single celled prokaryotes and eukaryotes can both possess flagella
The genetic combination of its parents
Answer:Chromosome is thread like structure composed of DNA and proteins, found in the nucleus of a cell. It carry genetic information in the form of genes.
Explanation:
For e.g Human has 23 pair of chromosome.
