Name ______________________ Date ____________

Tightly packed sheets of cells mark which tissue?
- Connective
- Epithelial
- Nervous
Which set lists all four families?
- Epithelial, connective, muscle, nervous
- Blood, bone, skin, hair
- Root, stem, leaf, flower
Muscle tissue carries messages as electrical impulses.
Circle one: True False
Bone bears weight while tendon resists pulling because of what?
- Their matrices differ: salts harden, fibres rope
- Their cells share nuclei
- Both lack any matrix
Why does epithelium sit on a basement membrane?
- To contract the sheet
- To dissolve the sheet
- Anchor, gate crossing
A section shows scattered cells in a sea of fibres. Which family?
- Epithelial
- Connective
- Nervous
A student calls scattered cells in matrix epithelial. What is the error?
- That pattern is connective, sheets are epithelial
- Matrix never exists
- Epithelium contracts
Long fibres packed with contractile proteins predict which job?
- Sending fast signals
- Filtering the blood
- Contraction

For grown-ups. Fold this page away before handing over the rest.

Epithelial · Sheets seal surfaces, which is the epithelial role.
Epithelial, connective, muscle, nervous · Those four families hold every tissue in the body.
False · Signalling is the nervous role, while muscle contracts.
Their matrices differ: salts harden, fibres rope · Matrix recipe decides the mechanical job.
Anchor, gate crossing · The boundary fixes the sheet and gates what passes below.
Connective · Spaced cells inside matrix is the connective pattern.
That pattern is connective, sheets are epithelial · The student swapped the two family patterns.
Contraction · Structure discloses function: contractile proteins contract.
