Ch 8 Test

Question 0

Process by which a cell surrounds and takes in material from its environment

Answer 0

Endocytosis

Question 1

Movement of materials from a region of lower concentration to a region of higher concentration but the cell must use energy

Answer 1

Active transport

Question 2

Expulsion or secretion of material from a cell

Answer 2

Exocytosis

Question 3

The passive transport of materials across the plasma membrane with the aid of transport proteins

Answer 3

Facilitated diffusion

Question 4

Concentration of solution = inside and outside cell

Answer 4

Isotonic solution

Question 5

Concentration of solution –> more inside cell, less outside

Answer 5

Hypertonic

Question 6

Concentration of solution –> more outside cell, less inside

Answer 6

Hypotonic

Question 7

The diffusion of water across a selectively permeable membrane

Answer 7

Osmosis

Question 8

Cell uses no energy to move certain particles across the membrane

Answer 8

Passive transport

Question 9

Anaphase

Answer 9

3rd stage
The separation of sister chromatids
The centromeres split apart and chromatid pairs from each chromosome separated from each other

Question 10

Sequence of growth and division of a cell

Answer 10

Cell cycle

Question 11

Cell membrane divides

Answer 11

Cytokinesis

Question 12

Interphase

Answer 12

1. Cell grows and protein production is high
2. The cell copies its chromosomes
3. Mitochondira and other organelles are manufactured and cell parts needed for cell division are assembled

Question 13

Metaphase

Answer 13

The spindle fibers attach themselves to the centromeres of the chromosomes and align the chromosomes at the middle of the cell

Question 14

Prophase

Answer 14

The dna molecules are progressively shortened and condensed by coiling to form visible chromosomes.
Enzymes break down the nuclear membrane and nucleolus so they are no longer visible.
Spindle fibers form which will attach to the chromosomes.

Question 15

Telophase

Answer 15

The chromosome pairs are pulled to opposite poles of the cell.
The nuclear envelope and nucleolus reform before the chromosomes uncoil, spindle fibers disintegrate

Question 16

How does cytokinesis occur in an animal cell?

Answer 16

Division among the cytoplasm

Question 17

How does cytokinesis occur in a plant cell?

Answer 17

They form a cell plate in the center to divide the cytoplasm
