Which of the following organelles is found uniquely in autotrophic, eukaryotic cells and not heterotrophic, eukaryotic cells? a. ribosomes b. rough endoplasmic reticulum c. chloroplast d. lysosomes What do all eukaryotes have that prokaryotes do not?...
Structure of a Prokaryotic Cell Prokaryotic cells have their genetic material present in a single chromosome within a central region of the cell's cytoplasm called the nucleoid. The cytoplasm of a cell is made up of semifluid mass called cytosol which surrounds intercellular structures called organel...
What are some differences between eukaryotic and prokaryotic cells? What do prokaryotic and eukaryotic cells have in common? What makes prokaryotic and eukaryotic cells similar to each other? What is the main characteristic of a eukaryotic cell?
Step-by-Step Solution:1. Understanding Prokaryotic Cells: - Prokaryotic cells are defined as cells that lack a true nucleus and membrane-bound organelles. They are simpler in structure compared to eukaryotic
Which of the following cells is most likely to be damaged by penicillin? gram-positive bacterial cells Which of the following is a difference between gram-positive and gram-negative cells? Only gram-negative cells have a lipopolysaccharide (LPS) layer. What statement most accurately describes the ...
一折射率为n的三棱镜，其截面为等边三角形，如图所示。一束单色光以入射角i从三棱镜左侧射入，经三棱镜后以折射角i从右侧射出，则()
have had more opportunity to evolve (by orders of magnitude) than plants or animals have had; accordingly, this predicts that prokaryotes should have the most functionally efficient, diverse and specialized of cells, despite their structural simplicity. The key to this paradox is the recognition ...
Cells are a part of every living thing. Various structures within cells carry out specific functions, such as making proteins or controlling cell activity. All cells, whether eukaryotic or prokaryotic, have the following components: plasma membrane- a physical barrier separating the inside from the ...
Nucleoid is the genetic material in prokaryotes. It does not have a nuclear membrane. Many bacteria contain small circular DNA called plasmid. Learn more aboutEukaryotic Cell here. Solved Example for You Q: The intracellular compartments are not found in which of the following cells?
