Which of the following statements are correct regarding the general difference between plant and animal cells?1. Plant cells have cellulose cell walls whilst animal cells do not.2. Plant cells do not have plasma membranes unlike animal cells which do.3. Mature plant cell has one large vacuole whilst an animal cell has many small vacuoles.Select the correct answer using the code given below:

a1 and 2 only
b2 and 3 only
c1 and 3 only
d1, 2 and 3 Science and Technology 571
✓ Correct answer: c) 1 and 3 only
ExplanationStatement 1 is correct: Both plants and animals contain eukaryotic cells, their cell structures are quite similar.The plasma membrane, nucleus, cytoplasm, ribosomes, and mitochondria in general make up each eukaryotic cell.The plant cell differs significantly from other cells in that it has a hard cell wall surrounding it.While the cells of other species are surrounded by a cell wall, cellulose and proteins are present in plant cells.Statement 2 is incorrect: Both plant and animal cells have a plasma membrane that surrounds the cytoplasm and regulates the movement of substances in and out of the cell.The plasma membrane is essential for maintaining homeostasis and facilitating communication between the cell and its environment in both plant and animal cells.Statement 3 is correct: A mature plant cell typically contains a single, large central vacuole, which can occupy up to 90% of the cell’s volume.This vacuole stores water, nutrients, and waste products and helps maintain turgor pressure, providing structural support to the plant.Animal cells often have multiple small vacuol
