Discover the essential organelles within cells, from ribosomes producing proteins to mitochondria generating energy. Unravel the genetic code encoded in DNA, the nucleus as the cell's control center, and the plasma membrane's vital role in maintaining homeostasis. Learn about the specialized functions of chloroplasts in plant cells and the structural support provided by the cell wall. Delve into the differences between eukaryotic and prokaryotic cells, understanding cell differentiation and the unique features of sperm, muscle, nerve, stem, blood, and animal cells. Explore the intricate world of cell biology and cellular processes.

Cell Vocabulary Unit 4
1. Ribosomes- Protein producing organelles; decode genetic material to assemble amino acids into proteins.
2. Mitochondria- Energy producing organelles; contain inner membranes (cristae) which increase surface area to allow for more ATP production.
3. Chloroplast- Specialized structures within plant cells that allow for photosynthesis to occur.
4. DNA- Genetic makeup which codes for all life, leads to cell specialization and expression of genetic traits (Deoxyribonucleic acid)
6. Plasma Membrane- Phospholipid bilayer surrounding all cells, allows for semi-permeability and homeostasis.
7. Cell Wall- Surrounds the cell membrane in plant cells; made of a rigid carbohydrate, cellulose, which maintains support and structure.
8. Organelles- Specialized structures in a cell that carry out the cell’s internal processes.
10.Prokaryotic Cell-A cell that does not have a true nucleus.
11. Cell- The basic unit of life; makes up all living organisms.
13. Vacuole- Organelles that take in excess water in a cell through the process of osmosis; larger in plant cells due to additional water intake.
14. Differentiation- Occurs when a less specialized cell is transformed into a more specialized cell.
15. Plant Cell- Eukaryotic cell containing membranebound organelles in addition to a cell wall and chloroplasts.
16. Muscle Cell- Cell that composes muscles, complete with many mitochondria and myofibrils for contraction.
17. Nerve Cell- Sends electrical and chemical signals that allow for communication and connections to be made.
18. Stem Cells- Cells that have not yet differentiated (embryonic and adult) and may become one of many different tissue types.
19. Blood Cell- Only cell in the body with no nucleus or DNA.
20. Animal Cell- Eukaryotic cell containing membrane-bound organelles without a cell wall or chloroplasts.
