Chapter 8-Cellular Transport And The Cell Cycle

Question 0

Endocytosis

Answer 0

Type of bulk transport(active) moves into cell

Question 1

Active transport

Answer 1

Uses energy, low to high

Question 2

Exocytosis

Answer 2

Type of bulk transport(active)

Goes out of cell

Question 3

Facilitated diffusion

Answer 3

Movement of molecules from high to low through a protein

Question 4

Hypertonic solution

Answer 4

Dissolved substance higher outside cell. Shrinks

Question 5

Hypotonic solution

Answer 5

Dissolved substance is higher inside cell. Swells

Question 6

Isotonic solution

Answer 6

Dissolved substance is same. Same

Question 7

Osmosis

Answer 7

Movement of water from high to low

Question 8

Passive transport

Answer 8

No energy used. High to low

Question 9

Anaphase

Answer 9

Centromeres split apart and chromatid pairs from each chromosome separate from each other. Chromatids pulled to opposite poles of the cell

Question 10

Cell cycle

Answer 10

Sequence of growth and division of a cell

Question 11

Centrioles

Answer 11

Small dark cylindrical structures made of microtubules located just outside the nucleus

Question 12

Centromere

Answer 12

Plays a role in chromosome movement during mitosis

Question 13

Chromatin

Answer 13

Strands of genetic material. DNA

Question 14

Chromosome

Answer 14

Cell structures that carry genetic material that is copied and passed from generation to generation

Question 15

Cytokinesis

Answer 15

The cells cytoplasm divides

Question 16

Interphase

Answer 16

Period of growth. Cells grow in size and carry on metabolism, chromosomes are duplicated

Question 17

Metaphase

Answer 17

Chromosomes attach to spindle fibers by their centromeres. Pulled by spindle fibers and line up on the equator of the spindle. One sister chromatid extends to one pole while the other extends to the opposite pole

Question 18

Mitosis

Answer 18

Process by which two daughter cells are formed, each containing a complete set of chromosomes

Question 19

What order?

- Organ systems, organism, organs, cells, tissue.

Answer 19

Cells – tissue – organs – organ systems – organism

Question 20

Prophase

Answer 20

Longest phase. Spindle forms. Centrioles move to opposite ends. Nucleus, nuclear envelope, Nucleolus begin to disappear. Chromosomes made of 2 halves

Question 21

Sister chromatid

Answer 21

Each half of chromosomes

Question 22

Spindle

Answer 22

Football-shaped, cage like structure consisting of thin fibers made of microtubules

Question 23

Telophase

Answer 23

Chromosomes unwind. Nucleolus reappears, nuclear envelope forms. Two distinct nuclei cells are formed
