What is the most complex level of body organization quizlet?
Starting with cells, the levels of organization in an organism become more and more complex. A tissue is more complex than a cell, an organ is more complex than a tissue, an organ system is more complex than an organ, and us, as organisms, are the final and most complex level of organization.
What are the levels of organization from most simple to most complex?
Summarizing: The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
What is the least complex level of organization?
Explanation. The body's level of organisation, from least complex to most complex are cells, tissues, organs and organ systems.
Is tissue more complex than an organ?
Question. Because its structure is more complex, a) a tissue has a more complex function than an organ.
Which of the following correctly lists the levels of organization from least complex to most complex?
The following sequence correctly lists levels of organization from simple to more complex: d) cell, tissue, organ, organ system.
What is the most complex organism?
A microscopic, see-through water flea is the most complex creature ever studied, genomically speaking. Daphnia pulex is the first crustacean to ever have its genome sequenced, and it turns out it has about 31,000 genes — 25 percent more than we humans.
What is the level of organization from least complex to most complex?
Explanation. The body's level of organisation, from least complex to most complex are cells, tissues, organs and organ systems.
Which part of the body is more complex?
The brain The brain is the body's most complex organ. There are around 86 billion neurons in the human brain, all of which are in use. Each neuron communicates with many other neurons to form circuits and share information.

What are the complex organisms?
A complex organism contains multiple organ systems with different functions. Multiple organisms of a single species may form a group, called a population. Many populations of different species form diverse communities, and communities that share the same geographical space are part of a larger ecosystem.
What is the most complex thing in the universe?
The brain The brain is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe. It contains hundreds of billions of cells interlinked through trillions of connections. The brain boggles the mind.
Which is the most complex human structure among the following?
The brain is the most complex organ in the human body. It produces our every thought, action, memory, feeling and experience of the world. This jelly-like mass of tissue, weighing in at around 1.4 kilograms, contains a staggering one hundred billion nerve cells, or neurons.
Is the most complex system in the human body?
There are about 200 different types of cells in the human body and over 37 trillion cells in total. The human brain is the most complex system in the known universe. It is a highly connected structure. Estimates vary, but it is reckoned there are approximately 86 billion neurons in the human brain.
Is hair the most complex?
Explanation: The answer is obviously the heart, with all the vessels that pass through it and how complex its structure is, it is more complex than the hair.
Which type of organisms is the most complex?
A microscopic, see-through water flea is the most complex creature ever studied, genomically speaking. Daphnia pulex is the first crustacean to ever have its genome sequenced, and it turns out it has about 31,000 genes — 25 percent more than we humans.
What is the name for a complex organized group of organisms?
Tissues form organs, and several organs may have interrelated functions in a cohesive organ system, such as the digestive system. A complex organism contains multiple organ systems with different functions. Multiple organisms of a single species may form a group, called a population.

What is the highest level of cell organization?
organism level The organism level is the highest level of organization. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life.
What is complexity in higher organisms?
Complexity give rise to bigger size of higher organism which in turn lead to requirement of more space energy and environmental resources than single cell organisms. 3. There is increase metabolic rate which consumes more food.

"We won't be able to understand the brain. It is the most complex thing in the universe," says Professor Sir Robin Murray, one of the UK's leading psychiatrists.
What is structure of complex system?
Complexity may arise from complicated (nonlinear) relations, but in this context it is primarily meant to express unexpected behaviour due to the interaction of a large number of simpler subsystems.
