A: The definition of a "tissue" is the level of organization higher than a cell but lower than an organ or organism. So a tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
Remember ALL cells of an organism (except the sexual gametes: sperm or egg) each contain the full DNA code of the living organism. But to function as a certain type of tissue cell only some of the DNA will be expressed, giving the cell very specific needed qualities. So the DNA expressed in a tissue cell is that which is needed by the cell to play its role to serve a certain organism or systemic purpose.

How does the DNA possessed by the cells of the different tissues of an organism differ from the DNA expressed by those cells?
Look in a book and stop asking on the Internet for answers
Could an organism have organs but no tissues. Explain?
No because in order to have organs you must have tissues. Organs are made out of tissues so there for an organism with organs must have tissues as well.
What is the second level of organization in a multicellular organism?
tissues yes TISSUES is the right answer
If the tissues organs and organ systems were injured and diseased what will happen to the organism?
Tissues are made of similar cells all working together for a similar function. Organs are made of different tissues all working together. And, organ systems are made of different organs working together to make an organism work. So, if any of these stop working, you could say that all the 'levels of organization' will come tumbling down and the tissues won't be able to continue in a dead organism. Eventually all the anabolic processes will do catabolic and the organism will be reduced into organic waste in biological reductionism.
List four levels of organization in order simplest to complex?
The most simple are the cells. They form tissues and different tissues form organs. Different organs form organ systems and all the organ systems together form an organism like you.

Is your heart a organ made out of muscle tissues nerve tissues and blood tissues?
Different cells work together to form tissues. Different tissues that work together form organs. Different organs that work together form organ systems and these work together to form an organism. Cells>tissues>organs>organs systems>organism.
What structure made of different tissues working together?
organism
Is the ear a organism?
yes, as it is made of tissues doing different things, and it has a function.
What makes organism?
Cells are the smallest things make an organism. Different cells have cells have different organelles. The same types of cells become tissues, tissues become organs, organs become organ systems, and organ systems become organisms. I hope this answered your question!
Could an organism have organs but no tissues. Explain?
No because in order to have organs you must have tissues. Organs are made out of tissues so there for an organism with organs must have tissues as well.
What groups form different tissues form?
Different types of tissues working together to perform a function make up an organ. cell-> tissue -> organ -> organ system -> organism
What is the answer to this describes a organism whose tissues are completely replaced by minerals?
An organism whose tissues are completely replaced by minerals is a fossil.
How does differentiation lead to tissues and organism a developing organism?
It leads to tissues because they need tissues for a cold during the SUMMER. For organs, IDK.
What can you about an organism with no tissues?
A unicellular organism lacks tissues, organs, and organ systems.
What is the process in certain multicellular organism by which special cells can grow new tissues out of different types?
Regeneration
