Cell Flashcard 2 Cp 23-24

Front

What are the levels of organization in biological systems from simplest to most complex?

Back

cell, tissue, organ, organ system

Front

What does PMAT stand for in the context of Mitosis?

Back

Prophase, Metaphase, Anaphase, Telophase

Front

What is the structure and function of a phospholipid?

Back

Phospholipids are molecules that make up the cell membrane, consisting of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

Front

What is the function of the cell membrane?

Back

The cell membrane controls what substances may enter or leave the cell.

Front

During which phase of Mitosis do chromosomes line up in the middle of the cell?

Back

Metaphase

Front

What is the primary function of tissues in multicellular organisms?

Back

Tissues are groups of similar cells that work together to perform a specific function.

Front

What is the role of organ systems in the body?

Back

Organ systems are groups of organs that work together to perform complex functions necessary for life.

Front

What occurs during Prophase of Mitosis?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during Anaphase of Mitosis?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the significance of Telophase in Mitosis?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.
