I believe you're talking about a population.
<span> it's a component of the outer walls of spores and pollen grains, and Bryophytes are mosses, so... I would assume that it's something that protects moss spores.</span>
The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.
<h3>What are the differences between animal and plant cells?</h3>
Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.
In plant cells it will have a cell wall that will be surrounded by a cell membrane. While animal cells will not have this cell wall.
Therefore, we can confirm that plant cells and animal cells will have differences in their content, function and organelles.

Answer:
Explanation:
Water Levels
For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved.
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.
