Lab 2- Cell Flashcards

Small organs that make up a cell are called

Structural and functional unit of all living things

Cell gave differences that reflect their specific functions in the body,
what functions are in common?

External boundary of cell,
regulates flow of materials into and out of the cell; site of the cell signaling

Scattered thoughout the cell; major site of ATP synthesis

Slender extensions of the plasma membrane that increases its surface area

Stored glycogen granules, crystals, pigments and so on.

Memranous system consisting of flattened sacs and vesicles; packages proteins for export

Control center of the cell; necessary for cell division and cell life

Two rod shaped bodies near the nucleus; direct formation of mitotic spindles (made of microtubles)

Dense, darkly stained nuclear body; package site for ribosomes

Contractile elements of the cytoskeleton

membranous system; involved in intracellular transport of proteins and synthesis of membrane lipids

Attached to membrane systems or scattered in the cytoplasm; synthesize proteins

Threadlike structures in the nucleus; contain genetic material, DNA

Site of free radical detoxification

Various sized sacs containing digestive enzymes (acid hydrolases)

A cell's life goes through 2 phases ________ and _____

The longest phase of a cell's life

The phase where cells reproduce

Cell division consists of a series of events which includes:

Mitosis is the division of the

Cytokinesis is the division of the

Products of Mitosis

Phases of Mitosis

Importance of mitotic cell division

The major structural difference between chromatin and chromasomes is that the latter are ________

Chromosomes attach to the spindle fibers by undivided structures called _____________

If a cell undergoes mitosis but not cytokinesis, the product is ________

The structure that acts as a scaffolding for chromosomal attachement and movement is called the _____________

_____________ is the phase of cell that don't undergo cell division

Two cell population in the body that do not under go cell division are _________ and ___________

The implication of an inability of a cell population to divide is that when some if its members die, they are replaced by __________

The mitosis phases where:
Chromatin coils and condenses, forming chromosomes

The Mitosis phase where:
The chromosomes are in V- shape

The Mitosis phase where:
the nuclear envelope reforms

The Mitosis phase where:
Chromosomes line up in the center of the cell along the equator (mid-line)

The mitosis phase where:
The nuclear envelope fragments and the mitotic spindle forms

The mitosis phase where:
DNA synthesis occurs, centrioles replicate

The mitosis phase where:
Chromosomes first appear to be duplex structures and chromosomal centromeres are attached to the kinetochore fibers.

The mitosis phase where:
Cleavage furrow forms

The two mitotic phases where the nuclear envelope is absent

Physical advantage of chromatin coiling and condensing?

Chromosomes connected by a small median body called ______ and an adhesive protein called ______.

Enzyme ______ promotes cleaving of cohesin and the centromere split in Anaphase
[resulting in 2 cromatids]
