Cell structure, function, and organization

Question 1

what is a cells 3 main parts

Answer 1

Plasma membrane
Cytoplasm
Nucleus

Question 2

Organelles function

Answer 2

carry out metabolic functions necessary to maintain the cell.. Also called cellular functions.

Question 3

Smooth endoplasmic reticulum function

Answer 3

site of lipid production and storage

Question 4

rough endoplasmic reticulum function

Answer 4

a cell organelle containing ribosomes that synthesizes and processes proteins in the cell

Question 5

Golgi apparatus function

Answer 5

where protein vesicles are modified, packaged, and transported to where they are needed. Golgi often referred to as the manufacturing and shipping department of the cell. also responsible for packing digestive enzymes within vesicles known as lysosomes

Question 6

Lysosomes function

Answer 6

Break down polymers. Necessary for cellular metabolism

Question 7

Mitochondria function

Answer 7

organelle changes food energy into usable cellular energy via the process known as cellular respiration. usable energy is adenosine triphosphate ATP

Question 8

In mitosis, one cell reproduces

Answer 8

into two genetically identical daughter cells

Question 9

Events of mitosis

Answer 9

interphase
prophase
metaphase
anaphase
telophase

Question 10

interphase

Answer 10

DNA replicates

Question 11

prophase

Answer 11

chromosomes condense, and visible chromosomes appear

Question 12

Metaphase

Answer 12

chromosomes align

Question 13

anaphase

Answer 13

chromosomes are pulled apart to the poles. Cell division begins

Question 14

telophase

Answer 14

two nuclei form. daughter cells separate

Question 15

Meiosis events

Answer 15

interphase
Meiosis I
prophase I
metaphase I
anaphase I
telophase I
Meiosis II
prophase II
metaphase II
anaphase II
telophase II

Question 16

Interphase in meiosis

Answer 16

DNA replicates

Question 17

prophase I

Answer 17

homologous chromosomes pair

Question 18

metaphase I

Answer 18

homologous chromosomes align

Question 19

anaphase I

Answer 19

homologous chromosomes pull to opposite ends of the cell

Question 20

telophase I

Answer 20

nuclear membranes form as the cell separates into two

Question 21

prophase II

Answer 21

daughter cells contain half the chromosomes of the original cell

Question 22

metaphase II

Answer 22

chromosomes align

Question 23

anaphase II

Answer 23

sister chromatids separate and move to opposite ends of the cells

Question 24

telophase II

Answer 24

nuclear membranes form as the two cells separate into four haploid daughter cells

Question 25

Tissues

Answer 25

groups of similar cells that work together to perform a shared function. 4 basic types of tissues

Question 26

4 basic types of tissues

Answer 26

epithelial tissue connective tissue muscle tissue nervous tissue

Question 27

epithelial tissue

Answer 27

covers body surfaces, lines body cavities, and serves as a protective barrier(e.g. skin)

Question 28

connective tissue

Answer 28

connects other tissues to each other and serves to bind and support body parts

Question 29

muscle tissue

Answer 29

moves the body and its contents by contraction

Question 30

nervous tissue

Answer 30

receives stimuli from the internal or external environment and communicates through electrical impulses with the rest of the body

Question 31

Levels to organization in multicellular organisms

Answer 31

atoms molecules organelles cells tissues organs organ systems living organism
