O cytoplasmencompasses all content between the plasma membrane and the core, that is, it occupies most of a cell. It is composed of hyaloplasm, cytoskeleton It is organelles.
It is a subject that has been heavily demanded in tests, therefore, it is a part of the cytology that deserves attention when studying.

O metabolism of the organelles present in the cytoplasm guarantee life to the organism, so it is important to know who they are and what the functions of each one of them are.
We prepared a list of exercises on cytoplasm and its components so you can test your knowledge on the subject.

1) In the cytoplasm of cells there are several organelles, performing different functions. Regarding the function performed by mitochondria we can state that:
a) It is responsible for the production of energy from carbon dioxide and glucose.
2) Which of the structures shown below are common in the cytoplasm of prokaryotic and eukaryotic cells?
a) Mitochondria and ribosomes.
b) Nucleus and lysosomes.
c) Chloroplast and Golgi complex.
d) Only the ribosome.
e) Plasmid and ribosome.
3) In eukaryotic cells, the cytoplasm represents the region located between the plasma membrane and the nuclear envelope. The material that forms this region is viscous, rich in water and ions and is called:
a) cell juice.
b) cytosol.
c) cellular organelle.
d) cistern.
e) intracellular fluid.
4) (PISM) The cytoskeleton is essential for the proper functioning of cells. About the cytoskeleton, it is incorrect to state that it:
a) is involved in the movement of sperm.
b) participates in the process of muscle contraction.
c) has centrioles as one of its components.
d) Its main components are different types of carbohydrates.
e) participates in adhesion between cells.
5) (UFMT) The first living beings on Earth appeared in the water about 3.5 billion years ago. Without water, scientists believe, life would not exist. It forms most of the volume of a cell, hence its importance in the functioning of living organisms. In cell:
a) the plastid retains most of the water, forming a dispersion called cytosol.
b) hyaloplasm is made up of water and protein molecules, forming a dispersion called colloid.
c) the lysosome is made up of water and protein molecules, forming a dispersion called cytosol.
d) the ribosome retains most of the water, forming a dispersion called a gel.
e) the endoplasmic reticulum retains most of the water, forming a dispersion called a colloid.
6) (UFVJM) Read the following information: in the cytoplasm of the cells are the organs that interact physiologically, performing different functions in maintaining the life of the various organs.
Based on this information and your knowledge, it is correct to state that:
a) The centriole participates in animal cell division.
b) The Golgi complex participates in the synthesis of lipids.
c) The lysosome is responsible for cellular respiration.
d) The smooth endoplasmic reticulum is responsible for protein synthesis.
7) The cytoplasm, contrary to what many think, performs movements that help transport molecules and carry out chemical reactions. When looking at an elodea leaf, an aquatic plant, for example, it is possible to clearly see cytoplasmic currents occurring all the time. These chains are called:
a) amoeboid movements.
b) pseudopodia.
c) cyclosis.
d) cellular contraction.
e) ciliary movement.
8) (PUC-RS) The cell cytoplasm is composed of organelles dispersed in an aqueous solution called cytosol. Water therefore plays a key role in the cell. Of the functions that water plays in the cytosol, which one is not correct?
a) Participates in osmotic balance.
b) Catalyzes chemical reactions.
c) Acts as a universal solvent.
d) Participates in hydrolysis reactions.
e) It participates in the transport of molecules.
9) (UFC) The cytoplasm of eukaryotic cells presents a set of thin and long fibers, of protein constitution, called cytoskeleton. Mark the alternative that presents a function of this structure in the cell.
a) Maintain the shape and support of bacteria.
b) Participate in the decondensation of chromosomes.
c) Allow digestion of various compounds in cells.
d) Enable the oxidation of organic substances inside the cell.
e) Allow the cell to adhere to neighboring cells and extracellular surfaces.
10) In the cytoplasm of a eukaryotic cell it is possible to observe several structures with varied functions that guarantee the survival of the cell. These structures are generically called:
a) cellular particles.
b) enzymes.
c) extracellular substances.
d) genetic material.
e) cytoplasmic organelles.
