Cell come from other cells because? - ✔✔All living things come from cells and
are from preexisting cells
Describe the Surface area-to - Volume Ratio - ✔✔As objects volume increases
the surface area increases also but not at the same rate.
Why do cells increase their surface to area ratio - ✔✔To obtain more substance
from the outside environment to grow.

List the structure features in a Prokaryotic cell - ✔✔1. Nucleoid
2. Cytoplasm
3. Ribosomes
4. Flagella or Pilia
5. Cell Walls
6. Internal Membranes
7. Cytoskeleton
What are Chromatin and what do they help structure? - ✔✔Chromatin is a
combination of proteins to form fibrous complex
Long threads of chromatin create Chromosomes
