Tissues - Unit 2

Question 1

gelatinous liquid that fills the inside of a cell and surrounds organelles

Answer 1

cytoplasm

Question 2

the fluid of cytoplasm. contains/dissolves nutrients, wastes, enzymes, and signaling molecules

Answer 2

cytosol

Question 3

the intracellular machinary. serval types. “machines that carry cell basic process”

Answer 3

organelles

Question 4

type of organelle: powerhouse of cell

Answer 4

mitochondria

Question 5

type of organelle: enclosed by a membrane. has O2 and makes most of the cell’s ATP. Looks like a kidney bean, red, and is copied from mom’s cell.

Answer 5

mitochondria

Question 6

type of organelle: produces protein by binding/transferring RNA. tiny, and at the site of translation in DNA.

Answer 6

ribosomes

Question 7

the highway of the cell

Answer 7

endoplasmic reticulum

Question 8

type of organelle: a network of membranous tubules continuous with the nuclear membrane

Answer 8

endoplasmic reticulum

Question 9

two parts of the endoplasmic reticulum

Answer 9

rough ER and smooth ER

Question 10

type of ER: contains ribosomes bound to surface. takes new proteins from ribosomes and folds them into their functional structure which then packaged into vesicles and delivered to Golgi apparatus

Answer 10

Rough ER

Question 11

type of ER: stores Ca^(+2), and makes steroid molecules. Lacks ribosomes.

Answer 11

Smooth ER

Question 12

type of organelle: receives proteins from rough ER and adds final modifications and folding to then become fully functioning then packaged in vesicles and delivered to parts of cell and out of cell through exocytosis. looks like waffle fries.

Answer 12

golgi apparatus

Question 13

type of organelle: post office of the cell.

Answer 13

golgi apparatus

Question 14

type of organelle: vesicles filled with digestive enzymes. they break down old/worn out/dysfunctional organelles by fusing to them (endocytosis). (aka chemical recycling).

Answer 14

lysosomes

Question 15

type of organelle: clean-up crew

Answer 15

lysosomes

Question 16

the protein network in the cytoplasm. it provides the cell with shape, strength, and a transportation system.

Answer 16

cytoskeleton

Question 17

3 elements in the cytoskeleton

Answer 17

microfilaments, intermediate filaments, and microtubules.

Question 18

type of cytoskeleton thats made of “actin” protein. gives cell its basic shape by forming scaffolding against the Plasma membrane. smallest.

Answer 18

microfilaments

Question 19

type of cytoskeleton. provides cell with strength/tear-resistance. attach to desmosomes.

Answer 19

intermediate filaments

Question 20

type of cytoskeleton that are tube-like proteins. they form transportation networks in cell. function as intercellular network that moves organelles and vesicles (like in mitosis). formed by small cylindrical structures (centrosomes).

Answer 20

microtubules

Question 21

control center of the cell

Answer 21

nucleus

Question 22

center of cell that contains DNA and generates RNA

Answer 22

Nucleus

Question 23

Nuclear Envelope is the ____

Answer 23

Nuclear Membrane

Question 24

Center of the Nucleus. constructs ribosomes

Answer 24

nucleolus

Question 25

DNA molecules that are packaged with proteins

Answer 25

Chromatin

Question 26

gives rise to tissue-growth/development and tissue repair. when the cell divides into 2 genetically identical cells.

Answer 26

cell division

Question 27

part of cell cycle where cell spends most of its life at. the cell is carrying out normal functions.

Answer 27

interphase

Question 28

4 steps of interphase

Answer 28

Gap 1, synthesis, gap 2, and gap 0

Question 29

part of interphase. cell generates enzymes/machinery to replicate its DNA

Answer 29

gap 1 (G1)

Question 30

part of interphase. cell replicates dna/chromatin

Answer 30

synthesis (S)

Question 31

part of interphase. cell generates enzymes and machinery to carry out cell division

Answer 31

gap 2 (G2)

Question 32

part of interphase. cell si suspended in interphase and doesn't divide. (aka most adult cells)

Answer 32

gap 0 (G0)

Question 33

4 steps of mitosis

Answer 33

prophase, metaphase, anaphase, telophase

Question 34

division of the nucleus in cell division

Answer 34

mitosis

Question 35

step 1 of mitosis. chromatin condenses into chromosomes. nuclear membrane breaks down. centrioles organize into centrosomes and microtubules

Answer 35

prophase

Question 36

step 2 of mitosis. chromosomes line up in the middle of cell and microtubules attach to each one.

Answer 36

step 3 of mitosis. chromosomes move to the poles of the cell. each pole receives one set.

Answer 37

anaphase

Question 38

step 4 of mitosis. 2 nuclei form

Answer 38

telophase

Question 39
