name ____________ class __________ date __________ section 3 review 7.1.f, 7.5.a section vocabulary function the special, normal, or proper activity on an organ or part organism a living thing; anything that can carry out life processes independently organ a collection of tissues that carry out a specialized function of the body structure the arrangement of parts in an organism organ system a group of organs that work together to perform body functions tissue a group of similar cells that perform a common function 1. list what are three benefits of being multicellular? ① __________ ② __________ ③ __________ 2. contrast fill in the chart below to contrast the levels of organization in an organism. level of organization description example the smallest unit that can perform all life processes heart muscle a collection of tissues that carry out a specialized function organ system circulatory system 3. compare how are structure and function different? __________ 4. explain what does \specialization of cells\ mean? ____________

Explanation:

1. Multicellular organisms can have cell - specialization, which allows different cells to perform different functions efficiently. They can also grow larger in size compared to unicellular organisms, giving them an advantage in accessing resources and avoiding predators. Additionally, multicellularity enables the development of complex body structures and systems for better adaptation to the environment.
2. The smallest unit that can perform all life processes is the cell. Heart muscle is a type of tissue, which is a group of similar cells that perform a common function. An organ is a collection of tissues that carry out a specialized function, for example, the heart. The circulatory system is an organ system, which is a group of organs that work together to perform body functions.
3. Structure refers to the physical form and arrangement of parts in an organism, while function is the special, normal, or proper activity that an organ or part can carry out. Structure provides the framework for function, and function is what the structure does.
4. Specialization of cells means that cells in a multicellular organism develop specific structures and functions to perform particular tasks. This allows for more efficient and coordinated functioning of the organism as a whole.

Answer:

1.

• Cell - specialization for efficient function.
• Ability to grow larger.
• Development of complex structures for adaptation.

2.

• Cell: the smallest unit that can perform all life processes; Example: any single cell in the body.
• Tissue: a group of similar cells that perform a common function; Example: heart muscle.
• Organ: a collection of tissues that carry out a specialized function; Example: heart.
• Organ system: a group of organs that work together to perform body functions; Example: circulatory system.

1. Structure is the physical form/arrangement, function is the activity an organ/part does. Structure supports function.
2. Cells develop specific structures and functions to perform particular tasks in a multicellular organism.
