Cells, Tissues, and Organs

Question 1

Specialized Cells

Answer 1

Each cell has chemical and physical differences (controlled by DNA coding and protein expression) that allow for specific functions.
Specialized cells derive from stem cells.

Question 2

Tissues

Answer 2

Specialized cells that are the SAME working together form TISSUES.
There are four basic types of animal cell tissue: muscle, epithelial, connective, and nervous

Question 3

Tissues (muscle tissue)

Answer 3

Lets body parts move and change shape but they do not tear easily.
Generate high ATP amounts.

Question 4

Tissue (muscle tissue types)

Answer 4

Skeletal- muscle tissue attached to the bone; movement of these muscles is VOLUNTARY (you have control over these muscles)
Cardiac muscle- muscle that’s exclusive to the heart (stronger and longer lasting than any other muscle type)
Smooth- muscles that are INVOLUNTARY, and move without any input from you

Question 5

Tissues (Epithelial Tissue)

Answer 5

Covers the external and internal body structures

Flat and thin, like skin cells.

Question 6

Tissues (Connective tissue)

Answer 6

Supports and connects cells and tissues

Question 7

Tissues (Nervous tissue)

Answer 7

Senses and passes along information.

Question 8

Organs

Answer 8

Made up of different tissues working together to perform a task
The same tissues do not have to make up an organ (can have multiple tissue types)
Multiple organs working together called an organ system
