Which of the following correctly describes contrasting features of a plant cell and an animal cell?
plant cells have a cell membrane, and animals have both cell walls and a cell membrane.
plant cells have lysosomes with enzymes, while animal cells have only the golgi apparatus.
plant cells have a large central vacuole that takes up most of the cell’s space, and animal cells have many smaller vacuoles.
plant cells have both rough and smooth endoplasmic reticulum, while animal cells have only smooth endoplasmic reticulum.

The correct answer is option Plant cells have a large central vacuole that takes up most of the cell’s space, and animal cells have many smaller vacuoles.

The coulees of the plant cells takes up a large volume of the plant cell structures, as they play a very important role in the maintenance of the turgor pressure in the plants. In the plant cell, generally have only one large vacuole. The animal cells have a large number of the vacuoles and the vacuoles are very smaller as compared to the vacuole of the plant cells.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom
