What is the structural and functional unit of living organisms?TissueCellOrganNucleusQuestion 1 of 202. Which type of cells lack a cell wall?Plant cellsFungal cellsAnimal cellsAlgal cellsQuestion 2 of 203. What is the main component of the cell wall?ProteinsCarbohydrates like cellulose and pectinLipidsNucleic acidsQuestion 3 of 204. What is the function of the cell wall?To allow all substances to enter the cellTo support and protect the cellTo produce energyTo store waste productsQuestion 4 of 205. What separates cell components from the outer environment?Cell wallNucleusPlasma membraneCytoplasmQuestion 5 of 206. What is the plasma membrane made of?Carbohydrates onlyProtein molecules embedded in two layers of phospholipidsA single layer of lipidsCellulose and pectinQuestion 6 of 207. Why is the plasma membrane called selectively permeable?It allows all substances to pass throughIt prevents all substances from enteringIt allows some substances to enter while preventing othersIt only allows water to passQuestion 7 of 208.
