Question 1

Which type of cellular junction attaches the junctional epithelium to the tooth surface?&#10;A) Cemental&#10;B) Lysosomal&#10;C) Desmosomal&#10;D) Hemidesmosomal

Hemidesmosomes are involved as a mechanism allowing gingival tissue to be secured to the tooth surface by the epithelial attachment.A hemidesmosome involves an attachment of a cell to an adjacent noncellular surface.

Question 2

Accepted Answer

The organelles are metabolically active specialized structures within the cell.Nuclear pores may pierce the nuclear envelope.In an actively dividing cell,the chromatin condenses into microscopically visible,discrete,rodlike chromosomes.The cytoplasm contains cavities or vacuoles.

Question 3

How many phases are within interphase when it occurs between cell division?&#10;A) One&#10;B) Two&#10;C) Three&#10;D) Four

Accepted Answer

Interphase has three phases: Gap 1,or G1 (initial resting phase: cell growth and functioning),Synthesis,or S (cell DNA synthesis by duplication),and Gap 2,or G2 (second resting phase: resuming cell growth and functioning).The cell division that takes place during mitosis between interphase consists of four phases: prophase,metaphase,anaphase,and telophase.

Question 4

Accepted Answer

The smallest living unit of organization in the body is the cell because each cell is capable of performing any necessary functions without the aid of other cells.Each cell has a cell membrane,cytoplasm,organelles,and inclusions.Thus,every cell is a world unto itself.

Question 5

The fluid part within the nucleus of the cell is considered to be:&#10;A) cytoplasm.&#10;B) nucleoplasm.&#10;C) nuclear envelope.&#10;D) tissue fluid.

Accepted Answer

The fluid part within the nucleus is the nucleoplasm,which contains important molecules used in the construction of ribosomes,nucleic acids,and other nuclear materials.The cytoplasm includes the semifluid part contained within the cell membrane boundary,as well as the skeletal system of support or cytoskeleton.The nucleus is surrounded by the nuclear envelope,a membrane similar to the cell membrane.The cells in each tissue type are surrounded by extracellular materials,which include both tissue fluid and intercellular substance.

Question 6

The semifluid part contained within cell membrane boundary is considered to be:&#10;A) nucleoplasm.&#10;B) cytoplasm.&#10;C) tissue fluid.&#10;D) nuclear envelope.

Accepted Answer

The cytoplasm includes the semifluid part contained within the cell membrane boundary,as well as the skeletal system of support or cytoskeleton.The fluid part within the nucleus is the nucleoplasm,which contains important molecules used in the construction of ribosomes,nucleic acids,and other nuclear materials.The cells in each tissue type are surrounded by extracellular materials,which include both tissue fluid and intercellular substance.The nucleus is surrounded by the nuclear envelope,a membrane similar to the cell membrane.

Question 7

Which of the following functions are performed by the Golgi complex within the cell?&#10;A) Metabolizes foreign compounds&#10;B) Produces ribosomes&#10;C) Packages protein compounds&#10;D) Produces energy for the cell

Accepted Answer

The Golgi complex is involved in the functions of segregation,packaging,and transport of protein compounds within the cell.

Question 8

The active transport of material from a vesicle within the cell out into the extracellular environment is termed:&#10;A) endocytosis.&#10;B) phagocytosis.&#10;C) exocytosis.&#10;D) interphase.

Accepted Answer

Exocytosis is an active transport of material from a vesicle within the cell out into the extracellular environment.The uptake of materials from the extracellular environment into the cell is endocytosis.Endocytosis can also take the form of phagocytosis,which is the engulfing and then digesting of solid waste and foreign material by the cell through enzymatic breakdown of the material.Interphase involves the cells engaging in growth,metabolism,organelle replacement,and substance production,including chromatin and centrosome replication between mitosis.

Question 9

When does the nuclear membrane reappear during mitosis?&#10;A) Metaphase&#10;B) Prophase&#10;C) Anaphase&#10;D) Telophase

Accepted Answer

During metaphase,chromosomes move so that their centromeres are aligned in the equatorial plane and then the nuclear membrane reappears.During prophase,chromatin condenses into chromosomes in cell.During anaphase,centromeres split,and each chromosome separates into two chromatids.During telophase,division into two daughter cells occurs.

Question 10

During what phase of mitosis does the chromatin condense within the cell?&#10;A) Metaphase&#10;B) Prophase&#10;C) Anaphase&#10;D) Telophase

Accepted Answer

During prophase,chromatin condenses into chromosomes in cell.During metaphase,chromosomes move so that their centromeres are aligned in the equatorial plane.During anaphase,centromeres split,and each chromosome separates into two chromatids.During telophase,division into two daughter cells occurs.
