I think the answer would be C.
<u>The presence of </u><u>embryos </u><u>is the features would definitively identify this organism as a </u><u>land plant.</u>
How could you determine if a plant is heterosporous?
Male and female reproductive structures are located on separate plants.
What is embryo of plant?
Definition. (botany) A young, developing plant, such as the rudimentary plant inside the seed of higher plants or that inside the archegonium of mosses and ferns.
What is embryo and its function?
- An embryo is an early stage of a multicellular organism's development.

<u>The complete question is -</u>
On a field trip, a student in a marine biology class collects an organism that has differentiated organs, cell walls of cellulose, and chloroplasts with chlorophyll a. Based on this description, the organism could be a brown alga, a red alga, a green alga, a charophyte recently washed into the ocean from a freshwater or brackish water source, or a land plant washed into the ocean. The presence of which of the following features would definitively identify this organism as a land plant?
Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
Answer:
Gamtetes are sex cells, for humans, this manifests as the sperm cell and the egg cell.
Explanation:
Gametes are haploid cells unlike most of our body cells that are diploid cells.
