which of the following are characteristics of all (with a few exceptions, such as parasitic plants) land plants?
□ diploid embryos
□ conspicuous sporophytes and microscopic gametophytes
□ the ability to photosynthesize
□ multicellular haploid and diploid generations
□ flowers and seeds

Explanation:

Land plants (with some exceptions like parasitic plants) generally have diploid embryos which develop from the zygote formed by fertilization. They exhibit alternation of generations with multicellular haploid and diploid generations. Most land - plants are capable of photosynthesis, which is a key characteristic for their autotrophic nature. Also, in land plants, the sporophyte generation is usually more conspicuous and the gametophyte generation is microscopic. However, not all land plants have flowers and seeds (e.g., mosses, ferns are land plants but are non - flowering and seedless).

Answer:

A. Diploid embryos
B. Conspicuous sporophytes and microscopic gametophytes
C. The ability to photosynthesize
D. Multicellular haploid and diploid generations
