b. animal cells contain mitochondria. plant cells do not.
c. animal cells contain chloroplasts. plant cells do not.
d. plant cells are surrounded by a cell wall. animal cells are not.
The statement that correctly describes a difference between plant and animal cell is ; ( D )
Eukaryotic cells which includes plants and animals cells have similar characteristics and slight differences. The main difference between a plant cell and an animal cell is the presence of cell wall in plant cells ( for the purpose of rigidity and protection ) and the absence of cell wall in animal cells and this is because animal cells are not rigid in nature and the cell membrane provides protection and shape for the animal cell.
Hence we can conclude that the the difference between the plant cell and animal cell is, Plant cells are surrounded by a cell wall and animal cells are not.

Answer:
D) Plant cells are surrounded by a cell wall. Animal cells are not.
Explanation:
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out, thus animal cells do not have cell walls. So therefore, D is the correct answer.
. Complex sugars are called polysaccharides.
Option C is correct
Monosaccharides are the simplest form of sugar, and they cannot be broken down any further. Disaccharides are made up of two monosaccharides joined together, and polysaccharides are made up of many monosaccharides joined together.
Some examples of polysaccharides include starch, cellulose, and glycogen. Starch is the main form of storage carbohydrate in plants, and it is made up of glucose molecules. Cellulose is the main structural component of plant cell walls, and it is also made up of glucose molecules. Glycogen is the main form of storage carbohydrate in animals, and it is also made up of glucose molecules.
Option C is correct

The sentence shown in the question above, about the existence of natural and artificial lakes and ponds, is true.
Natural lakes and ponds are formed by the accumulation of water in land depressions created by glacial activity, earthquakes, and volcanic craters, among others.
Artificial lakes and ponds are created by human activity, usually to store water for irrigation of crops or other agricultural activities.
