The material cells secrete around themselves, holding a tissue together, is the:
AA thick cell wall
BThe cell cortex
CThe basal lamina

Answer & Solution
Correct answer: D. Extracellular matrix
1. Animal cells are not simply pressed against one another.
2. They secrete materials into the space around them.
3. Collectively, these materials are called the extracellular matrix.
4. A cell wall is a plant structure, so it cannot be the general animal-tissue answer.
