Answer: SPORES are defined as haploid (1n) cells which develops into gametophytes.
Gametophytes inturn produce either haploid (1n) male or females GAMETES that can fuse to form diploid ZYGOTES.
This basically explains what goes on in Meiosis.
Scientists are helping to improve understanding of how rocks in Earth's hot, deep interior enable the motions of tectonic plates, which regulate the water cycle that is critical for a habitable planet.
Answer:
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Explanation:
A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.
