Compare and Contrast Plant and Animal Cells

In 2013, average Americans used about 80 times the energy that was provided by their diets, which has been called having 80 energy slaves, but that understates the reality. A barrel of oil provides about one year of the calories needed to fuel a human body, but if that oil were used to power machines, it would perform more than ten man-years of work, often doing work that humans could not perform in any case, such as propelling an automobile. Each American really has several hundred energy slaves working for him/her, which is why the average American lives a richer lifestyle than Earth’s richest human of two centuries ago. In 2013, the energy in the oil wrested from Earth’s crust contained enough energy to power several hundred energy slaves. Add in the other energy resources, and industrialized humanity rode on the backs of about one energy slaves. In today's industrialized nations, humans perform a tiny fraction of one percent of the actual work done; energy-powered machines perform more than 99.9% of it. In contrast, the reproduction of intelligence is in its infancy. In 2012, humanity's 500 most powerful supercomputers achieved the combined computing power of three human brains. The day that each human has even one "mind slave" is a distant future event.

Comparing Plant cells and Animal cells Lab Report

Some things to pass through and not others. The semi-permeable cell membrane will allow water to enter or leave the cell through osmosis. Plant cells can absorb water through osmosis but will not break because of the cell wall. Animal cells do not have a cell wall. What this means to animals is that they must excrete any excess water that the cells cannot hold.

After learning what plants need for growth, try in your science desk or kitchen science lab. Kids will to see the changes over time and watch the sprouts and roots.

Rather, we can hypothesize that each organism is composed of different cells and that the cell size varies with the particular kind and function of each cell (for instance, see the discrepancy in the size of different human cells).

Comparing Plant and Animal Cells

As is clear, a human is many times larger than a butter cup plant which goes to show that size of cell and size of organism are not directly correlated.

A tree's cells will not be larger than an acorn's cells simply because of the size difference.Cheek Cells
