- 14. YOU COMPLETE ME! DIRECTIONS:Each group will be given a word puzzle about the parts of the cell. They will locate and encircle the parts of the cell in the table below. After finding the parts of the cell, they will correctly label the parts of the cell. The group will be given 10 minutes to finish the activity.
- 15. PARTS OF THECELL
- 16. PARTS OF THECELL 1. CELL MEMBRANE • also called Plasma membrane • It is a semipermeable membrane which allows the entry of some substances like water, oxygen, and ions and prevents the entry of others. • Toxic or useless by-products of metabolism can exit through it.
- 17. PARTS OF THECELL 1. CELL MEMBRANE The cell membrane functions as: a. The boundary between the cell and its external environment. b. As a structure that controls the movement of substances in and out of the
- 18. PARTS OF THECELL 1. CELL MEMBRANE • The cell membrane allows the cell to change its shape when needed. • The cell wall is an additional boundary aside from the cell membrane, surrounding the cells of plants, fungi, bacteria and other protozoans.
- 19. PARTS OF THECELL 1. CELL MEMBRANE • It is made up of cellulose which provides support and protection from injury. • Cellulose is a good source of fiber in our diet.
- 20. PARTS OF THECELL 2. CYTOPLASM • found inside the cell membrane surrounding the nucleus. • It is made up of fluid like substance where organelles are located. • It is composed of water, salts, proteins, fats, carbohydrates, and other chemicals.
- 21. PARTS OF THECELL 2. CYTOPLASM • t is the medium for chemical reaction. • It provides a platform upon which other organelles can operate within the cell. • All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
- 22. ORGANELLES FOUND INTHE CYTOPLASM PARTS OF THE CELL
- 23. PARTS OF THECELL a. Mitochondria • often referred to as the powerhouses of the cell • main function is to generate the energy necessary to power cells
- 24. PARTS OF THECELL a. Mitochondria • the energy produced is important for the vital activities of cell, such as growth and reproduction.
- 25. PARTS OF THECELL b. Ribosomes • ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell
- 26. PARTS OF THECELL b. Ribosomes • he ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
- 27. PARTS OF THECELL c. Endoplasmic Reticulum • are folded membranes that divide the cell into compartments. • They serve as channels through which the materials are transported in the cell.
- 28. PARTS OF THECELL c. Endoplasmic Reticulum • Its composition has two components: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER)
- 29. PARTS OF THECELL c. Endoplasmic Reticulum • the SER is generally used for the creation/ storage of lipids and steroids, while the RER plays a significant role in the synthesis of various proteins.
- 30. PARTS OF THECELL d. Golgi complex • It serves as the packaging factories of the cell.
- 31. PARTS OF THECELL d. Golgi Complex • Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
- 32. PARTS OF THECELL e. Lysosomes • are spherical sacs that contain powerful digestive enzymes. • they destroy bacteria and other microorganisms that invade the cell.
- 33. PARTS OF THECELL e. Lysosomes • they break down excess or worn-out cell parts. • If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
- 34. PARTS OF THECELL f. Plastids • are energy converters. • they harvest solar energy and produce food in the process of photosynthesis
- 35. PARTS OF THECELL f. Plastids • Plastids are pivotal subcellular organelles that have evolved to perform specialized functions in plant cells, including photosynthesis and the production and storage of metabolites.
