Within the cytoplasm, the major organelles and cellular structures include: (1) nucleolus (2) nucleus (3) ribosome (4) vesicle (5) rough endoplasmic reticulum (6) Golgi apparatus (7) cytoskeleton (8) smooth endoplasmic reticulum (9) mitochondria (10) vacuole (11) cytosol (12) lysosome (13) centriole.
What is the correct order of size of organelles?
It can be as tiny as a microbe, or a complex as a human. When referring to a multicellular organism, the correct order from smallest to largest is-- organelle, cell, tissue, organ, system, organism.
What is the correct order of size of organelles from largest to smallest?
And many organelles working together form a cell. With this knowledge, we can answer our question. The correct order of the structures from largest to smallest is cells, organelles, molecules, atoms.
What is the correct order that the organelles are used in during the production of a protein?
Nucleus has instructions for making proteins; Nucleolus makes ribosomes; Ribosomes make proteins; ER transports proteins within cell; Golgi packages proteins which can then be exported through the cell membrane.
What is the order of cell components?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Which is largest and smallest cell?
The largest cells is an egg cell of ostrich. The longest cell is the nerve cell. The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm.
What is the correct order of size from smallest to largest of K K+ Ca and Ca2+?
Answer: In such a series, size decreases as the nuclear charge (atomic number) of the ion increases. The atomic numbers of the ions are S (16), Cl (17), K (19), and Ca (20). Thus, the ions decrease in size in the order S2– > Cl– > K+ > Ca2+.
What is larger than a cell?
Tissues are groups of cells that perform a common function, such as skeletal muscle tissue or fat tissue. They are therefore larger than cells. Organisms are made up of organs which are made up of tissues, and are therefore larger than tissues. Population, organism, tissue, cell, organelle, molecule.
What are two steps of protein synthesis?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Which two organelles are most important in the production of proteins in a cell?
Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cells DNA is surrounded by a membrane. Therefore, the nucleus houses the cells DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
Which ion is larger Ca2+ or Mg2+?
Cations are smaller than their parent atoms, and so the Ca2+ ion is smaller than the Ca atom. Because Ca is below Mg in group 2A of the periodic table, Ca2+ is larger than Mg2+. Consequently, Ca > Ca2+ > Mg2+.
What is the radius of Mg2+?
Metallic, Covalent and Ionic Radii(r)*Atom/Ionr(pm)Lu172Lu3+86Mg160Mg2+7221 more rows
What are the levels of organization in the human body from smallest to largest?
It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity, such as (from smallest to largest): chemicals, cells, tissues, organs, organ systems, and an organism.
What is the correct order of protein synthesis?
Therefore the correct sequence is- DNA is transcribed, RNA is modified into mRNA, A ribosome binds to mRNA, Amino acids are lined up in a sequence, Chemical bonds are formed and a protein is produced.
What are the examples of organelles?
The nucleus, the mitochondrion, the chloroplast, the Golgi apparatus, the lysosome, and the endoplasmic reticulum are all examples of organelles. Some organelles, such as mitochondria and chloroplasts, have their own genome (genetic material) separate from that found in the nucleus of the cell.
