Answer:
Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses.
Total molar concentration of all dissolved solutes of the hypotonic solution is less than that of the cell<span> cytoplasm. ... Thus when a </span>cell<span> is placed in hypotonic solution it tends to receive </span>water and<span> </span>swells up<span>. An animal </span>cell<span> may even </span>swell<span> and burst, plant </span>cells are saved because of the presence of cell<span> wall.</span>

Land plants are evolved from green algae.
Green algae called charophytes are coolest relatives of land plants.
It is believed that land plants are the most closely related to green algae, more specifically, a group of green algae referred to as charophyceans. Not only do both land plants and green algae produce chlorophyll a and b, but other evidence suggests that there is a relationship as well.
4 key traits that appear in nearly all land plants but are absent in the charophytes.
-Diploid embryos
- The ability to photosynthesize
-Apical meristem
-Walled spores produced in sporangia.
- Multicellular haploid and diploid generations
-Multicellular gametangia
