animal cell works differently than plant cell
animal cell have million of cell as well plant..
animal cell have four key part ..plant cell have cell wall,chloroplasts, vacuoles 
Explanation:
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants.
Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.
Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present. Large vacuoles help provide shape and allow the plant to store water and food for future use. The storage function plays a lesser role in animal cells, therefore the vacuoles are smaller.

Read the Explanation below.
Explanation:
1. I agree with the claim because you can see overall there is no difference in plant growth or variation if a plant has 30 ml of water or none at all.
2. I would measure the change in growth over a greater period of time to get a more accurate data set.

The endosperm is formed through double fertilization where one male gamete nucleus with polar nuclei to form a triploid nucleus called the primary endosperm. The endosperm therefore will contain 15 chromosomes since the polar nuclei is diploid and the male gamete is haploid forming a triploid nucleus.
