Cells and Tissues — HS Anatomy & Physiology practice questions

12 multiple-choice questions and 12 flashcards on Cells and Tissues, about 8% of the HS Anatomy & Physiology bank. Every one carries a written rationale.

What this chapter covers

Cells and Tissues is one of 13 chapters in CoStudy's HS Anatomy & Physiology bank, and it holds 12 of the bank's 150 multiple-choice questions — roughly 8% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.

Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.

3 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.

Which epithelium forms the outer skin, where protection from abrasion matters most?

  1. Simple squamous
  2. Simple columnar
  3. Transitional
  4. Stratified squamous

Answer: D — Stratified squamous

D) Correct — Many layers of flat cells can be worn away and replaced. A) A single thin layer would tear easily. B) Lines the stomach and intestines. C) Lines the bladder, letting it stretch.

In diffusion, particles move:

  1. from low to high concentration
  2. only when ATP is used
  3. from high to low concentration
  4. only through protein pumps

Answer: C — from high to low concentration

C) Correct — No energy is needed; particles spread down their gradient. A) Moving against the gradient is active transport. B) Diffusion is passive. D) Pumps are used in active transport.

Which tissue covers body surfaces, lines cavities, and forms glands?

  1. Connective
  2. Muscle
  3. Nervous
  4. Epithelial

Answer: D — Epithelial

D) Correct — Epithelium lines and covers, and forms most glands. A) Supports and binds other tissues. B) Contracts to produce movement. C) Sends electrical signals.

Cells and Tissues flashcards

3 cards from the 12 in this chapter.

Ribosomes, ER, and Golgi?

Ribosomes build proteins (many sit on the rough ER). The Golgi apparatus modifies, packages, and ships them.

Cell membrane structure?

A phospholipid bilayer with embedded proteins. Selectively permeable: small nonpolar molecules cross easily; ions and large molecules need proteins.

Four tissue types?

Epithelial (covering), connective (support), muscle (movement), nervous (signal).
