Question

Compare plants, animals, and fungi, considering these components: cell wall, chloroplasts, plasma membrane, food source, and polysaccharide storage. Be sure to indicate fungi’s similarities and differences to plants and animals.

a) Plants have cell walls made of cellulose, chloroplasts for photosynthesis, animals lack cell walls but have glycogen storage, while fungi have chitin cell walls and polysaccharide storage.
b) Plants have chitin cell walls, chloroplasts, animals have cellulose cell walls, while fungi use glycogen for energy storage.
c) Plants have chitin cell walls, animals lack cell walls, while fungi store energy as glycogen.
d) Plants lack cell walls, animals have chitin cell walls, while fungi store energy as starch.

Answer 1

Plants have cell walls made of cellulose and chloroplasts for photosynthesis, storing energy as starch. Animals lack cell walls, consume organic materials for food, and store energy as glycogen.

Step-by-step explanation:

Comparison of Plants, Animals, and Fungi

When comparing plants, animals, and fungi, several components are essential: the cell wall, chloroplasts, plasma membrane, food source, and polysaccharide storage.

Plants have a cell wall made of cellulose, which provides structure to the plant. They also have chloroplasts, allowing them to perform photosynthesis to make their own food. For energy storage, plants typically use starch, a polysaccharide.

Animals lack a cell wall but do have a plasma membrane that contains a phospholipid bilayer. Animals are heterotrophs, deriving their food by consuming organic substances. They store energy as glycogen, another polysaccharide.

Fungi have a cell wall containing chitin, not cellulose. Unlike plants, fungi are heterotrophs as they cannot carry out photosynthesis and must obtain their nutrients externally. Fungi also store energy as glycogen, similar to animals.

Thus, the correct statement that describes these differences is: 'Plants have cell walls made of cellulose, chloroplasts for photosynthesis, animals lack cell walls but have glycogen storage, while fungi have chitin cell walls and polysaccharide storage.'
