Oksana_A [137]
The three structures found in plant cells that aren't found in animal cells are the cell wall, chloroplast, and the large central vacuole. The cell wall is a hard outer covering that allows plant cells to keep their shape. Chloroplast contain the pigment known as chlorophyll and allow plants to undergo photosynthesis. Finally, the large central vacuole is there to allow plants to store lots of water.

lilavasa [31]

She would mostly see plants grow around the banks of the lake. In addition, she might see some plants growing in the lake.

The plants are majorly aquatic plants. The ones on the banks are emergent plants because their roots are submerged in water and their foliage is above water. They grow on the shores because it shallow there. Free-floating aquatic plants may grow in the lake because they are suspended on the water surface with their roots just floating underneath the water surface.

What are the properties of water, and how do they help to sustain life on earth?
ANTONII [103]

The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.

Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.

Due to this, water resists tendency to evaporate or to vaporize and  therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.
