Levels Of Orgnization Flashcards
What’s A cell?
A basic unit of life.
What happens in the first 3 stages of the embryonic system?
The embryo changes shape.
What happens after the first 3 stages of the embryonic system?
The organ gets formed properly.
What happens in the last 3 stages of the embryonic system?
The organs gets bigger and stronger.
TRUE OR FALSE: The organ is the second level of organization.
False.
Its the tissue
The stem cells/embryonic cells are..
Highly specialized cells.
What’s determination?
The stage were the cells decides to be one type of cells and they are committed into becoming one type of cells even if it got transplanted to another part of the body.
What’s differenction?
The stage were the cells decide either acquire or function a specialized structure.
What’s a tissue?
A group of different types of cells all together.
What’s an organ?
Different types of tissues together.
What’s an organ system?
A group of organs working together.
A type of organs..?
Kidney, liver, lung, etc..
Define the sensors (receptor).
The sensors gather information about conditions inside and outside the body.
What compares information with the set points in the body?
The control center.
Define the targets.
An organ, tissue, or cell that changes its activity in response to the message sent from the neurons.
Define the communication system.
The communication system is the nervous/endocrine system which they carry functions throughout the body.
What happens when cells gets turned on & off?
It allows the stem cells to preform specialized tasks.
An egg and a sperm combined results in..?
A zygote.
The dividing of the zygote cell is called..?
An embryo.
What’s the difference between tissues and stem cells?
Tissues are made of different types of cells unlike the stem cells, as they’re made of indifferent types of cells.
What are the similarities between the stem cells and tissues?
They all make organs.
List the 4 types of tissues.
- Muscular
- Nervous
- Connective
- Epithelia
What’s the function of the muscular tissue?
Allows movement and depending on the function and its amount it needs mitochondria.
What’s the function of the nervous tissue?
controlling body activities.
What’s the function of the connective tissue?
Provide support to the cells/organs.
What’s the function of the epithelia tissue?
Works as a protective barrier.
TRUE OR FALSE: stem cells can copy all the 4 types of tissues.
True, but for human they can copy only the bone marrow and the production of blood.
List the specialized cells.
- Red blood cells.
- Nerves system.
TRUE OR FLASE; there are 1000 types of cells.
False, only 200.
Define the feedback.
The feedback is the information from the sensors that allows a control center to compare current conditions to a set of values.
What system maintain homestatis and eliminate waste product?
Excrectory system.
What’s apoptosis?
The process of the death of cells.
