Ch 4 Act 8 - Tissue ID Activity

The Tissue ID Activity requires students to identify different types of tissues in the body, categorize them, and highlight incorrect descriptions. The assignment includes a table with various tissue types and descriptions, where students must determine the correct tissue type and subtype, as well as identify which description does not belong. This exercise aims to enhance understanding of tissue classification in biology.

Ch 4 Act 8 - Tissue ID Activity (3 pts each; 45 pts total)
The table below describes various types of tissues found in the body. In each row, one of the descriptions is incorrect and does not belong.
You are to figure out:
1) the category of tissue being described (epithelial, connective, muscle or nervous)
2) which subtype (simple squamous, fibrocartilage, etc.) it is, choosing from the list provided.
3) which description does not belong
 Type in the correct tissue type (E, C, M, N) and subtype in the first column
 Highlight or strike out the incorrect answer
Tissues to be considered:
adipose areolar blood cardiac muscle dense irregular dense regular elastic elastic cartilage fibrocartilage
hyaline cartilage nervous tissue osseous (bone) – compact pseudostratified columnar reticular simple columnar
simple cuboidal simple squamous skeletal muscle smooth muscle stratified squamous (keratinized)
stratified squamous (nonkeratinized) transitional
The first tissue has been done as an example.
