Similar cells working together in a group to carry out a function

• Cells

• Tissues

• Organs

• Organ Systems

• Organism

Answer explanation

Tissues are groups of similar cells that work together to perform a specific function, distinguishing them from individual cells, organs, organ systems, and organisms, which are more complex structures.

Many different tissues working together in a group to carry out various functions

• Cells

• Tissues

• Organs

• Organ Systems

• Organism

Answer explanation

Organs are made up of different tissues that work together to perform specific functions, making them the correct answer. Cells form tissues, tissues form organs, and organs can be part of organ systems.

Many different organs working together in a group to carry out various functions

• Cells

• Tissues

• Organs

• Organ Systems

• Organism

Answer explanation

Organ systems consist of multiple organs working together to perform specific functions, making them the correct answer. Cells and tissues are smaller units, while organisms refer to complete living entities.

What is the correct sequence of the Levels of Organization? (Smallest to Largest)

• Cells, Tissues, Organs, Organ Systems, Organism

• Organism, Organ Systems, Organs, Tissues, Cells

• Organs, Cells, Tissues, Organ System, Organism

• Tissues, Cells, Organism, Organ System, Organs

Answer explanation

The correct sequence of the Levels of Organization from smallest to largest is: Cells, Tissues, Organs, Organ Systems, and finally Organism. This reflects the hierarchical structure of biological organization.

Select each part of the Cell Theory

• all cells arise from existing cells

• cells are the basic unit of structure and function

• all living things are made of cells

• cells must have a nucleus

Answer explanation

The Cell Theory states that all cells arise from existing cells, cells are the basic unit of structure and function, and all living things are made of cells. The statement about cells needing a nucleus is incorrect.

These are the two categories of cells:

• Prokaryotes

• Eukaryotes

• Dikaryotes

• Multikaryotes

Answer explanation

The two main categories of cells are Prokaryotes, which lack a nucleus, and Eukaryotes, which have a defined nucleus. Dikaryotes and Multikaryotes are not primary categories of cells.

ALL cells have:

• a cell membrane

• a nucleus

• genetic material

• ribosomes

Answer explanation

All cells have a cell membrane, genetic material, and ribosomes. However, not all cells have a nucleus, as prokaryotic cells lack one. Therefore, ribosomes, a cell membrane, and genetic material are essential features of all cells.
