This document summarizes the key structures and functions of animal and plant cells. It describes the cell membrane, nucleus, cytoplasm, cytoskeleton, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, mitochondria, cell wall, and chloroplasts. The main differences between animal and plant cells are that plant cells contain chloroplasts and a cell wall, while animal cells do not.
2 03 cell structure and function
- 1. John Christopher E. Pangilinan Biology Ms. Pyles 1/17/14
- 2. 2.03 Cell Structure and Function • Cell membrane • Nucleus • Cytoplasm & cytoskeleton • Ribosome • Endoplasmic reticulum • Rough ER • Smooth ER • Golgi Apparatus • Lysosomes • Vacuoles • Mitochondria • Cell wall • Chloroplasts
- 3. The Animal and Plant cell • The Animal and Plant cell are almost alike but they usually have different types of cell structure. The only difference is that plant cells have chloroplasts and cell walls and animal cell don’t.
- 4. What do they look like? Animal Cell PLANT CELL
- 5. Cell Membrane • The cell membrane is called the “ Plasma Membrane” • The cell membrane serves as a barrier to determine whether what things can enter the organelle and what things can leave the organelles. • Made of lipids (fats) and contains proteins
- 6. Nucleus The nucleus usually holds most of the cell’s genetic information. What is inside the Nucleus? The nucleus inside is that DNA and proteins are packed together into a chromosomes.
- 7. Cytoplasm & Cytoskeleton • Cytoplasm is a “ thick fluid that is surrounded of the cell. • The cytoplasm contains a mixture of water and salt that is dissolved, ions ,and the organic molecules. • Cytoskeleton was discovered by a new improved technology of the microscope. What scientist found are fiber in the cell.
- 8. Ribosomes • The ribosomes are the protein synthesis in a cell. • They are made up of RNA and protein molecules. • The ribosome’s job is to synthesize the proteins whether if they are free or connected.
- 9. Endoplasmic reticulum The endoplasmic reticulum Known as (ER) The endoplasmic reticulum is divided into 2 sections that differ between the structure and the function. It is a maze of membranes.
- 10. Rough ER • The rough ER’s appearance is rough • Small ribosome covers the surface. • The rough ER can make their own proteins and fats (lipids) to the membrane. The portions of the endoplasmic reticulum forms to sacs called “ transport vesicles”. They carry proteins from the rough endoplasmic reticulum to the Golgi apparatus.
- 11. Smooth ER • The membrane does not have any ribosome. • The smooth endoplasmic reticulum takes part of the metabolic process. • The appearance of Smooth ER is smooth.
- 12. Golgi Apparatus The Golgi Apparatus modifies proteins. The Golgi Apparatus transports vesicles from the ER by transporting proteins.
- 13. Lysosomes The lysosomes contains enzymes in a membrane sac. Each cell contains different enzymes that break down into a macromolecules.
- 14. Vacuoles • Vacuoles are known as “ membrane- enclosed sacs that serves storage functions. • The vacuoles are larger.
- 15. Mitochondria • The Function of the mitochondria is that the organelles act like a cell’s digestive system by taking nutrients and break them down to release energy to give the cell to power up. • ATP is produced.
- 16. Cell wall • The cell wall is usually found in the plant cell. • They are not found in the animal cell. • The cell wall surrounds the cell membrane and giving the support by adding a layer of protection for the plant cells.
- 17. chloroplasts • The chloroplasts is usually found in the plant cell. • The chloroplasts is not found in the animal cell. • The color of the organelle is green because the chloroplasts contain the green pigment chlorophyll.
