Cellular Organization

Front

Order of organization in living things from most basic to most complex?

Back

Cell, tissue, organ, organ system, organism

Answer explanation

The correct order of organization in living things from simplest to most complex is: cell, tissue, organ, organ system, organism. This reflects how cells combine to form tissues, which then form organs, leading to organ systems and finally the complete organism.

Front

A group of similar cells that come together to perform a specific function is a/an

Back

tissue

Answer explanation

A group of similar cells that work together to perform a specific function is called tissue. Tissues combine to form organs, while organs work together in organ systems, and all these make up an organism.

Front

When a group of organs work together to perform a particular function they create a/an

Back

organ system

Answer explanation

When a group of organs works together to perform a specific function, they form an organ system. This is distinct from an organism, tissue, or organ, which refer to different biological structures or levels of organization.

Front

The smallest level of organization of life in an organism

Back

cell

Answer explanation

The smallest level of organization in an organism is the cell. Cells are the basic building blocks of life, forming tissues, organs, and organ systems, making them fundamental to all living organisms.

Front

The cell is the building block of all living things.

Back

True

Answer explanation

True is correct because the cell is indeed the fundamental unit of life, serving as the basic building block for all living organisms.

Front

A group of organs that work together to perform big jobs for your body is an organ system.

Back

True

Answer explanation

True. An organ system is indeed a group of organs that collaborate to perform significant functions for the body, such as the circulatory or digestive systems.

The basic unit of structure and function in the human body is the....

Back

cell

Answer explanation

The basic unit of structure and function in the human body is the cell. Cells are the smallest living units that perform essential functions, while tissues, organs, and organ systems are made up of groups of cells.

Front

Which is an example of an organism? Options: a beetle, a lake, a rock, a shell

Back

a beetle

Answer explanation

A beetle is an example of an organism because it is a living creature that belongs to the animal kingdom. In contrast, a lake, a rock, and a shell are non-living entities.

Front

What is the difference between a cell and a tissue?

Back

Cell is basic unit of life; tissue is group of cells that work as one.

Answer explanation

A cell is the basic unit of life, while a tissue is a group of cells that work together to perform a specific function. This makes the first answer choice correct.

Front

What are the three parts of cell theory?

Back

1. All life is made of cells
2. Cells are the basic unit of life
3. Cells come from other cells

Answer explanation

The three parts of cell theory are: 1) All life is made of cells, 2) Cells are the basic unit of life, and 3) Cells come from other cells. This highlights the fundamental role of cells in biology.
