Questions and Answers

Why did plants become multicellular?

Plants evolved multicellularity as a response to changes in their environment and the need to adapt to new ecological niches.

Multicellular plants developed specialized tissues like roots, stems, and leaves, which enhanced their ability to absorb nutrients and perform photosynthesis.

Multicellularity allowed plants to grow larger and develop structural support systems which are essential for withstanding gravity and environmental forces. (correct)

Plants became multicellular to increase their reproductive capabilities and ensure the survival of their species.

What is unicellularity?

Unicellularity refers to the characteristic of an organism or life form being composed of a single cell. (correct)

Unicellularity is the ability of an organism to reproduce asexually through cell division.

Unicellularity refers to the characteristic of an organism or life form being composed of multiple cells.

Unicellularity is a biological characteristic describing organisms composed of multiple cells that are organized into various specialized structures and tissues.

What is multicellularity?

Multicellularity is a biological characteristic describing organisms composed of multiple cells that are organized into various specialized structures and tissues. (correct)

Multicellularity is the ability of an organism to undergo cellular respiration.

Multicellularity refers to the characteristic of an organism or life form being composed of a single cell.

Multicellularity is the ability of an organism to reproduce sexually through the fusion of gametes.

Study Notes

The Evolution of Multicellularity in Plants

Unicellularity refers to the state of being a single-celled organism, where all functions are performed by one cell.
Multicellularity, on the other hand, is the state of being composed of multiple cells that work together to form a functional organism.

The Advantages of Multicellularity

Multicellularity provided plants with a range of benefits, including increased size, improved structural support, and enhanced ability to adapt to environmental changes.
With multiple cells, plants could differentiate and specialize, allowing for more efficient use of resources and improved overall function.

Specialized Tissues in Multicellular Plants

Multicellular plants developed specialized tissues, such as xylem, phloem, and epidermis, which enabled them to perform specific functions more effectively.
Xylem tissues are responsible for transporting water and minerals from roots to leaves, while phloem tissues transport sugars and other organic compounds produced by photosynthesis.
Epidermis tissues form the outer layer of the plant, providing protection and regulation of water loss.
