Plant Specialized Cells Functions Quiz

Study Notes

Guard Cells in Plants

Control the opening and closing of stomata, regulating gas exchange and transpiration.
Respond to environmental conditions such as light and humidity.

Plant Cell for Nutrient Distribution

Phloem cells are responsible for transporting organic nutrients, primarily sugars, throughout the plant for growth and energy.

Cell Membrane Functions

Serves as a protective barrier that controls the movement of substances in and out of the cell.
Maintains homeostasis by regulating ion concentration and nutrient uptake.

Energy Production Organelle

Mitochondria are the cellular organelles known as the powerhouses, producing energy (ATP) through cellular respiration.

Cytoskeleton Function

Provides structural support and shape to the cell.
Facilitates intracellular transport and cell division, enabling movement and organization of organelles.

Trichomes Function on Plant Surfaces

Aid in reducing water loss by creating a barrier against evaporation.
Protect plants from herbivores by providing a physical barrier and may secrete irritating substances.

Cell Adhesion Molecules

Though cell adhesion molecules primarily facilitate cellular connections, they do not directly aid in nutrient transport.

Tissue Barrier Function

Epithelial tissue acts as a barrier, protecting skin and internal organs from pathogens, injury, and dehydration.

Vascular Tissue in Plants

Composed of xylem and phloem, primarily responsible for the transport of water, nutrients, and sugars to various parts of the plant.

Statements about Organs

Organs are specialized structures composed of different tissue types; any claim that they do not have distinct functions or structures is not true.

Organ Detoxification and Metabolism

The liver plays a crucial role in detoxifying chemicals, metabolizing drugs, and regulating biochemical synthesis within the body.

Role of Tissues in Cell Organization

Tissues serve to organize groups of similar cells that perform specific functions, contributing to overall organ and system efficiency in multicellular organisms.
