Detailed explanation-1: -Eric’s report is about the organelle that supports and gives structure to plant cells. Which organelle is Eric writing about? A. Chloroplast.
Detailed explanation-2: -An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.
Detailed explanation-3: -Plant cells have a cell wall, as well as a cell membrane. The cell wall provides structural support and protection. This gives the plant cells their distinct rectangular or pentagonal shape.
Detailed explanation-4: -Ans : (b) Chloroplast Chloroplasts are present only in plant cells.
Detailed explanation-5: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
