UNIT 3: 20 QUESTIONS REVIEWER

Cellular level of organization

Which level of organization in the human body involves the interactions and functions of various types of specialized cells, each with specific roles and functions?

The force with which pure water moves into a solution due to solute concentration

What is osmotic pressure?

Permeability and Impermeable

______ determines what moves in and out of a cell, and a membrane that lets nothing in or out is ______.

Diffusion

It is a net movement of a substance from an area of higher concentration to an area of lower concentration.

Cytoplasm

It contains two centrioles at right angles; each centriole is composed of 9 microtubule triplets in a 9+0 array.

Channels

It regulate water flow and solutes passing through membranes.

Peripheral proteins

Bound to inner or outer surface of the membrane

Microfilaments

Which structure within the cell is responsible for maintaining its shape and providing structural support?

Mitochondria

Which organelle is responsible for generating energy in the form of ATP in cells?

Individual cells

What is the primary focus of the cellular level of organization in the human body?

Lipid synthesis and detoxification

What is the primary function of the endoplasmic reticulum?

Osmosis

 Diffusion of water across a selectively permeable membrane

Plasma membrane

Separates the cytoplasm from the extracellular fluid

Ribosome

Which cellular structure is responsible for the synthesis of proteins within the cell?

Golgi apparatus

Which organelle is responsible for packaging and transporting proteins within the cell?

Osmotic Pressure

It is the force with which pure water moves into a solution as a result of solute concentration.

Microvilli

These are the extensions of the plasma membrane containing microfilaments.

Endoplasmic reticulum

Which organelle is responsible for the synthesis and packaging of proteins within the cell?

Carrier

It transports specific solutes through the membrane

Cell
