Solution
1. True-Cells are made up atoms and these are bound together by specific bonds which may lead
vital functions of these cella. Different types of atoms bound to another and determined thae
shape and size.
2.True- Two or more tissues bound together to perform specific function.
3. False- All human cell does not contain nucleus,organelles, cytoplasm and cell
membrane.Example Erythrocytes dont have nucleus.
4. True- plasmma membrane is made up of lipid bilayer which protect it form outer disturbing
elements, having channels for transport and enzymes for proper functiong.
5. False- Active transport
6.True
7. False
8.True
