The answer is C. cell wall. Plant cells have a cell wall while animal cells do not. Plant cells' cell wall is mostly made of cellulose, which is a polysaccharide.
Reproduction in plants can be by vegetative propagation, through the vegetative propagules like the rhizomes or tubers, asexual reproduction by the production of spores and sexual reproduction by the formation of the male and female gametes.
Spores are the agents of asexual reproduction in plants. They are formed in the non-seed-bearing plants like the liverworts, hornworts, mosses and ferns. The ferns are the group of vascular plants that reproduce by spores. The leaves of the ferns (fronds) contain numerous sporangia which produce tiny spores. When the sporangia breaks open, the spores are released and dispersed by the wind. On encountering favourable conditions of the environment, these spores grow into tiny plants called the gametophytes.

Answer:
Explanation:
About 10,00 years ago, ancient farmers in what is now Mexico took the first steps in domesticating corn when they simply chose which kernels (seeds) to plant. These farmers noticed that not all plants were the same. Some plants may have grown larger than others, or maybe some kernels tasted better or were easier to grind. The farmers saved kernels from plants with desirable characteristics and planted them for the next season's harvest. This process is a example of selective breeding. Corn cobs became larger over time, with more rows of kernels, eventually taking on the form of modern corn.
This makes the plant more useful because corn is the primary U.S. feed grain, accounting for more than 95 percent of total feed grain production and use. More than 90 million acres of land are planted to corn, with the majority of the crop grown in the Heartland region. Most of the crop is used as the main energy ingredient in livestock feed. In conclusion, more corn will help the environment, crops and living beings.
