Cell

THE PLASMA MEMBRANE IS SELECTIVE ABOUT WHAT PASSES THROUGH IT, IT ALLOWS NUTRIENTS TO ENTER THE CELL BUT KEEPS OUT UNDESIRABLE SUBSTANCES, THIS IS CALLED THE _________________________ OF THE PLASMA MEMBRANE

Selective Permeability

WHAT IS THE FUNCTION OF THE CYTOSKELETAL ELEMENTS?

scaffolding of cell

NAME ONE CYTOSKELETAL ELEMENT

Microtubules

GIVE ONE OF THE FUNCTIONS OF THE MICROTUBULES

Microtubules produce parts of the spindle.

_______________IS THE PROCESS OF NUCLEAR REPLICATION AND DIVISION RESULTING IN DAUGHTER CELLS WITH EXACT COPIES OF NUCLEAR MATERIAL

Mitosis

WHAT IS THE STRUCTIONAL AND FUNCTIONAL UNIT OF ALL LIVING THINGS

Cell

WHAT IS THE FUNCTION OF MICROVILLI?

folds or finger-like projections in the plasma membrane

Increasing Surface Area, increase nutrient absorption

WHAT IS THE JELLY-LIKE MATERIAL IN WHICH THE ORGANELLES FLOAT?

Cytosol

GIVE THE NAME FOR THE SPECIFIC TYPE OF ENZYMES FOUND IN PEROXISOMES

*Oxidases, including catalase

GIVE THE NAME FOR THE SPECIFIC TYPE OF ENZYMES FOUND IN LYSOSOMES

digestive enzymes/hydrolytic enzyme/ protease

GIVE THE NAME FOR THE INNER MEMBRANE FOLDS OF THE MITOCHONDRIA

*Cristae

WHAT ARE THE PROTEINS THAT FORM THE MICROTUBULES CALLED?

*Tubulin

NAME ONE OF THE TWO PROTEINS THAT MAY FORM MICROFILAMENTS

*Actin

NAME ONE OF THE TWO STRUCTURES THAT MAY BE FORMED FROM THE CYTOSKELETAL ELEMENTS

cilia

GIVE ONE OF THE FUNCTIONS OF THE MICROFILAMENTS

Microfilaments allow for cell movement and plasma membrane stability. structure and flexible

GIVE ONE OF THE FUNCTIONS OF THE INTERMEDIATE FILAMENTS

Intermediate Filaments help resist mechanical/ pulling forces on the cell.

________________ IS THE ABILITY OF THE PLASMA MEMBRANE TO ALLOW CERTAIN SUBSTANCES INTO THE CELLS AND KEEP OTHERS OUT/ ALSO KEEPS VALUABLE SUBSTANCES WITHIN THE CELL

Selective Permeability

____________ IS NUCLEAR DIVISION THAT TAKES PLACE IN REPRODUCTIVE ORGANS GIVING RISE TO FOUR GENETICALLY DIFFERENT DAUGHTER CELLS, WITH HALF THE NORMAL GENETIC NUMBER AS SOMATIC CELLS

*Meiosis

GIVE ANOTHER NAME FOR THE IDEALIZED GENERALIZED CELL THAT IS STUDIED TO LEARN GENERAL STRUCTURES AND NOT SPECIFIC CELL FUNCTION

*Composite cell

THE CELL CYTOPLASM CONTAINS VARIOUS SUBSTANCES AND STRUCTURES THAT ARE NOT PART OF THE ACTIVE METABOLIC ACTIVITY OF THE CELL, SUCH AS STORED FOODS, PIGMENT GRANULES, CRYSTALS, WATER VACUOLES AND INGESTED FOREIGN MATERIALS, THEY ARE COLLECTIVELY CALLED ________________________

Inclusions

A CELL'S ________________ IS THE SERIES OF CHANGES IT GOES THROUGH FROM THE TIME IT IS FORMED UNTIL IT REPRODUCES ITSELF

Cell Cycle

DURING _________________ THE CELL GROWS AND CARRIES OUT IT'S USUAL ACTIVITIES

Interphase

NAME ONE OF THE TWO STAGES OF THE CELL'S LIFE CYCLE

Interphase

CENTROMERES AND _____________, AN ADHESIVE PROTEIN, HOLD REPLICATED CHROMOSOMES (CHROMATIDS) TOGETHER DURING PROPHASE OF MITOSIS

*Cohesin

THE STRAIGHT LINE THAT REPLICATED CHROMOSOMES LINE UP ALONG DURING METAPHASE IS CALLED THE ________________

metaphase plate

________________ IS THE ENZYME THAT CLEAVES COHESIN AT THE BEGINNING OF OF ANAPHASE

*Separase

_______________ IS THE DIVISION OF THE CYTOPLASMIC MASS DURING LATE ANAPHASE CONTINUING THROUGH TELOPHASE OF MITOSIS

Cytokinesis

IN ANIMAL CELLS, A ______________ BEGINS TO FORM APPROXIMATELY OVER THE SPINDLE EQUATOR AND EVENTUALLY SPLITS OR PINCHES THE ORIGINAL CYTOPLASMIC MASS INTO TWO PORTIONS

cleavage furrow
