tissues/stem

Question 1

tissue

Answer 1

collection of similar cells that perform specific function

Question 2

organ

Answer 2

structure of diff tissues working together to perform specific body function

Question 3

four types of tissue

Answer 3

epithelial, connective, muscle, nerve

Question 4

epithelial (ex, description, function)

Answer 4

ex skin, lining digestive system

• tightly packed cells covering surface and lining internal organs

Question 8

stem cell

Answer 8

(animal) a cell that can differentiate into into many diff cell types

Question 9

cellular differentiation

Answer 9

cell becomes specialized to perform specific function

Question 10

what can stem cells differentiate into

Answer 10

epithelial muscle and nerve tissues

Question 11

two types of stem cells

Answer 11

• embryonic (differentiate into any kind of cell)

- tissue stem cells (exist within specialized tissue, can only differentiate into certain type of cells)
