ORGANZATION OF LIVING THINGS
How are the human being cells? (According to organization-type- and nutrition)
Eukaryotic and heterotrophic.
Name the basic structures of an eukaryotic cell.
Plasma membrane, cytoplasm and nucleous.
The cell membrane is semipermeable. What does it mean?
It only allows the passage of certain substances.
Name the tissue.
It is a rigid tissue, due to the great amount of minerals that are deposited in its matrix. It supports the organism.
Bone tissue.
Which systems control and coordinate the organism?
Nervous and endocrine systems.
What is a tissue?
Group of specialized cells that work together to perform a specific function.
What is the function of the nucleous?
It controls the vital functions.
How is the free passage of small molecules, such as oxygen and carbon dioxide from greater to lower concentration called?
Diffusion.
Name the tissue.
Composed of cells that accumulate fat. Their
main function is to be an energy reserve, although it also has other functions.
Adipose tissue.
Systems involved in reproduction.
Female and male reproductive systems.
What is an organ?
It is formed by several different tissues that join together to perform a particular function.
Which organelle produces energy for the cell?
Mitochondria.
In osmosis, what molecule moves across the membrane?
Water.
Name the tissue.
Lining the surface of the body, both the outside (skin) as well as hollow cavities that communicate with it, such as the digestive and respiratory tract (mucous).
Epithelium tissue.
Why is respiratory system involved in nutrition?
Because it carries the oxygen that cells need to the blood.
Name ALL the levels of organization of the human being, from the smallest one alive to the biggest one.
Cell, tissue, organ, system and organism.
Which organelle produces proteins?
Ribosomes.
Sometimes the concentration of substances is less in the exterior of the cell and they can't go through the membrane by the process of diffusion.
If the substances are essential for the cell, the cell can incorporate them by wasting energy.
What is the name of this process?
Active transport.
Name the tissue.
It allows the skeleton to move and it contracts voluntarily.
Striated muscle tissue.
Which systems or/and organs perform nutrition?
Digestive, respiratory, circulatory and excretory systems.
List all the systems of the human body.
Digestive, respiratory, circulatory, excretory, nervous, endocrine, skeletal , muscular and reproductive systems.
Which organelle stores substances?
Vacuole.
Describe the endocytosis process.
Sometimes the cell needs to incorporate large particles that cannot go through the plasma membrane. When this happens, the membrane collapses to encompass the particles and forms a small vesicle that is incorporated into the cytoplasm.
Name the tissue.
Special type of tissue because it has striated fibres, but contracts involuntarily.
Cardiac muscle tissue.
Which systems or/and organs perform interaction?
Nervous system, endocrine system, sense organs, skeletal system and muscular system.
