Exam 3: Cells

The lysosome plays an important role in apoptosis (cell suicide).

Which organelle contains its own DNA molecule?

Define or explain the following terms: hypertrophy, atrophy, hyperplasia, neoplasm, anaplasia, benign neoplasm, and malignant neoplasm.

The term hypertrophy means that there has been an increase in size of individual cells.

During which phase of mitosis are chromosomes aligned in the center of the cell?

Flagella are extremely fine hairlike extensions on the exposed surface of certain cells.

Which structure has ribosomes attached to it and helps transport proteins throughout the cell?

Describe or give the function of the following organelles: ribosomes, smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes, centrioles, microvilli, and cilia.

Which structure programs the formation of ribosomes?

If a messenger RNA molecule contains the sequence uracil-adenine-cytosine, what would be the nucleotide sequence for the transfer RNA it would attract?

Match each organelle or cell structure to its corresponding function or description. -Organelle that produces new membranes for the cell

Match each phase of the cell life cycle to its corresponding description. -DNA replication occurs

Cellular respiration occurs in which organelle?

The difference between rough and smooth endoplasmic reticulum is that the rough endoplasmic reticulum has ribosomes attached to it.

The term organelle refers to proteins that are embedded in the cell membrane.

What is a gene?

The Golgi apparatus consists of two small rods that play an important role in cell division.

The end product of the process of transcription is a messenger RNA molecule.

Match each organelle or cell structure to its corresponding function or description. -Structure made up of phospholipids and cholesterol molecules

Cellular respiration occurs in the Golgi apparatus.
