Division of a cell into two daughter cells occurs during which phase of mitosis?
- The last phase of mitosis in which the the individual cell divides
During which phase of mitotsis does the cell DNA (deoxyribonucleic acid) in the form of chromatin condense into chromosomes?
Movement and alignment of the chromosomes themselves in the middle of the cell occurs during which phase of mitosis?
During which phase of mitosis do the chromosomes separate and migrate to opposite poles of the cell?
Cellular metabolism occurs in the:
C. endoplasmic reticulum
D. Golgi appartatus
The "power plants of the cell are responsible for the rate of energy production
(this multiple choice question has been scrambled)
Sperm, erythrocyte,macrophage, osteocyte and neuron are all examples of this component of the body.
Muscle, cartilage, bone,and blood are all examples of this component of the body
A somewhat independent body part that performs a specific function or functions
The skin, brain, heart, liver, can function together as these components of the body
These are metabolically active specialized structures dispersed throughout the cytoplasm within the cell membrane
These organelles are produced by the Golgi complex
The endoplasmic reticulum (ER) may be classified as either _____ or ______
smooth or rough
Secretory substances such as mucus for the salivary glands or insulin for the pancreas are proteins that have been modified, concentrated,and wrapped up in large numbers into a single membranous vesicle by this organelle.
The cells in each tissue type are surrounded by extracellular materials which include both tissue fluid and intercellular substance. ___________________ is one of the most common ingredients of intercelluar substance.
Various types of thicker, thread-like microscopic structures within the cell
Match fhe following explanations of intercellular junctions with their correct terms:
1 An intercellular junction which involves an attachment between cells
2 An intercellular junction which involves an attachment of a cell to an adjacent non-cellular surface
3. The type of junction that occurs at the basement membrane between epithelial and connective tissue
4. Tends to cause regularly plump cells to appear prickled or star-shaped
