Which of the following statements about algae and plants is true?

• A. Plant cells have rigid cellulose walls, and algal cells do not.
• B. Both plant and algal zygotes develop into embryos.
• C. Algae have different types of chlorophyll molecules from plants.

• E. Plants have a waxy, waterproof cuticle, and algae do not.

Answer: (E)

Verified step by step guidance

1. Understand the structural differences between plant and algal cells. Plant cells have rigid cellulose walls, which provide structural support and protection. Algal cells also have cell walls, but they can vary in composition and are not always rigid like those of plants.
2. Consider the reproductive processes of plants and algae. In plants, the zygote develops into an embryo, which is a key stage in the life cycle. Algae, however, do not typically develop zygotes into embryos in the same way as plants.
3. Examine the types of chlorophyll molecules present in plants and algae. Both groups perform photosynthesis, but they may use different types of chlorophyll molecules. For example, plants primarily use chlorophyll a and b, while algae can have chlorophyll c and other variants.
4. Distinguish between the cellular organization of plants and algae. Plants are generally multicellular organisms, with complex structures and tissues. Algae can be unicellular or multicellular, but many are unicellular, which differentiates them from plants.
5. Identify the presence of a waxy, waterproof cuticle in plants. This cuticle helps prevent water loss and provides protection against environmental factors. Algae typically do not have this feature, as they often live in aquatic environments where water retention is not a concern.
