According to research these are the 7 Characteristics of Life:
<span> 1. Living Things are Composed of Cells:</span>
<span>Single-cell organisms have everything they need to be self-sufficient.In multicellular organisms, specialization increases until some cells do only certain things.</span>
<span>2. Living Things Have Different </span>Levels of Organization:
<span>Both molecular and cellular organization.Living things must be able to organize simple substances into complex ones.<span><span>Living things organize cells at several levels:
</span><span><span>Tissue<span> - a group of cells that perform a common function.</span></span><span>Organ<span> - a group of tissues that perform a common function.</span></span><span>Organ system<span> - a group of organs that perform a common function.</span></span><span>Organism<span> - any complete living thing.</span></span></span></span></span>
Lit is a lichen,a combination of an algae and a fungi
Answer:
They speed up chemical reactions. Without them you wouldn't be alive. They break down macromolecules, and also lower the amount of energy needed for a chemical reaction to happen.
Respiration is how animal cells get their energy to preform their necessary functions. Plant cells don't use respiration, because they use photosynthesis. Photosynthesis turns light into energy.
Tid-bit of info:
Cellular Respiration Formula:
Sugar + Oxygen = Carbon Dioxide + Water <span>+ ATP </span>
C₆H₁₂O₆ + O₂ = CO₂ + H₂O <span>+ ATP </span>
Photosynthesis Formula:
Sunlight + Water + Carbon Dioxide = Oxygen + Sugar
Sunlight + H₂O + CO₂ = O₂ + C₆H₁₂O₆
