Answers
Answer:
1. Tissue is a group of cells that have similar structure and that function together as a unit.
2. Plants have eukaryotic cells with large central vacuoles, cell walls containing cellulose, and plastids such as chloroplasts and chromoplasts. Different types of plant cells include parenchymal, collenchymal, and sclerenchymal cells. The three types differ in structure and function.
3. Labile cells are continuously dividing and include surface epithelial cells such as stratified squamous epithelial cells of the skin and columnar epithelial cells of the gastrointestinal tract.
6. Skeletal muscles are attached to the skeleton by tough connective tissues called tendons(see Figure above). Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.
