Which correctly describes cells, tissues, organs, and organ systems?
The smallest unit of organization is a cell, a group of cells working together for a specific purpose is an organ, and a group of tissues working together makes up an organ system.
The smallest unit of organization is a tissue, a group of tissues working together for a specific purpose is an organ, and a group of organ systems working together is a cell.
The smallest unit of organization is a tissue, a group of tissues working together for a specific purpose is a cell, and a group of organ systems working together is an organ.
The smallest unit of organization is a cell, a group of tissues working together for a specific purpose is an organ, and a group of organs working together is an organ system.
Which of the following is not an organ within the hierarchical organization of a plant?
Stems
Flowers

Petals
The image shows cells with different appearances, sizes, and shapes. Why do different types of cells have different shapes and sizes?
Different cells are specialized to perform different functions. The shape and size will form specialized tissue based on the structure of the cell.
Cells have different sizes and shapes due to environmental conditions.
Different sizes and shapes help provide cells with the ability to morph from one cell to another.
Sizes and shapes are impacted by the amount of nutrition the cell has received.
The hierarchical organization in plants is similar to the hierarchical organization in animals in that both have:
a single level of organization
a complex structure with multiple levels
no organization
only one type of cell
In a plant, how does tissue differ from an organ? How are they similar?
Tissues are made of similar cells, while organs are made of different tissues working together. Both are essential for plant function.
Tissues are made of different tissues working together, while organs are made of similar cells. Both are essential for plant function.
Tissues and organs are both made of similar cells and perform the same function.
Tissues and organs are both made of different tissues working together and perform the same function.
Which cell theory is true?
Some organisms are composed of one or more cells
All cells are from preexisting cells
The organs are the basic unit of structure and organization in organisms
Animals are only from preexisting cells
