Assessment presentation

  1. 1. Assessment presentation Kayla Edwards 3rd period
  2. 2. standard • Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including the cell membrane in maintaining homeostasis and cell reproduction
  3. 3. Cells
  4. 4. What’s the difference between a prokaryote and a eukaryote • do not have a • Prokaryotes are not found in humans and eukaryotes are • Prokaryotes are always and are • Prokaryotes reproduce and divide by and eukaryotes reproduce and divide by and nucleusprokaryotes eukaryotesunicellular multicellular Binary fission mitosis meiosis Vocab 1. Prokaryotes- any cellular organism that has no nuclear membrane, 2. Nucleus- the control center of all cells 3. Multicellular-composed of several or many cells. 4. Unicellular-composed of one cell 5. eukaryotes- any cellular organism that has a nuclear membrane 6. Binary fission- asexual reproduction in unicellular organisms by division of two daughter cells 7. Meiosis-the type of cell division that results in four daughter cells with half the number of chromosomes of the parent cell 8. Mitosis- a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent cell.
  5. 5. What are some similarities of prokaryotes and eukaryotes • Both have a • Both have a • Both contain • They both have Cell membrane cytoplasm Genetic material ribosomes Vocab 1. Cell membrane- the semi permeable membrane surrounding the cytoplasm of a cell. 2. Cytoplasm- the material or protoplasm within a living cell, excluding the nucleus. 3. Genetic material- materials found in the nucleus, which play a fundamental role in determining the structure and nature of cell substances.(Dna or rna) 4. Ribosomes- Small round particles in a cell made up of rna and protein
  6. 6. Functions of cell organelles
  7. 7. Cell wall a tough, flexible but sometimes fairly rigid layer that surrounds some types of cells. Location – prokaryotic cells Function-support and protect the cell
  8. 8. Cell membrane The cell membrane is the semi permeable membrane surrounding the cytoplasm of a cell. Location-both prokaryotic and eukaryotic cells Function- controls movement of materials in/out of cell and maintains homeostasis
  9. 9. How does the cell membrane maintain homeostasis • The cell membrane is a double phospholipids membrane. This keeps water from flowing through when sodium or potassium concentrations are higher or lower on one side of the membrane. Vocab Homeostasis- The process carried out by the human body to maintain a constant temperature.
  10. 10. Nucleus The nucleus is the control center of the cell location- eukaryotic cells Function-controls the cells activities
  11. 11. Nuclear membrane The double-layered membrane surrounding the nucleus of a eukaryotic cell, separating the nucleus from the cytoplasm. Location-eukaryotic cells Function- Controls movement of materials in and out of nucleus
  12. 12. cytoplasm The cytoplasm is the material or protoplasm within a living cell, excluding the nucleus. Location- both eukaryotic and prokaryotic cells Function- supports ands protects cell organelles Vocab 1. the colorless material comprising the living part of a cell, including the cytoplasm, nucleus, and other organelles
  13. 13. Endoplasmic reticulum (e.r) The endoplasmic reticulum is a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane Location-eukaryotic cells Function- carries materials through cell
  14. 14. Ribosome Ribosomes are Small round particles in a cell made up of rna and protein Location- both eukaryotic and prokaryotic cells Function- produces proteins Vocab 1. Rna – ribonucleic acid 2. Protein- any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms
  15. 15. mitochondrion A mitochondrion is a rod shaped organelle found within the cytoplasm of eukaryotic cells Location- eukaryotic cells Function- breaks down sugar molecules into energy Vocab 1. Organelle- any of a number of organized or specialized structures within a living cell.
  16. 16. vacuole A vacuole is a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid Location-eukaryotic cells(more prone in plant cells) Function- store food, water, waste
  17. 17. lysosome A lysosome is a cell organelle containing enzymes that digest particles and that disintegrate the cell after its death . Location-eukaryotic cells Function- breaks down larger food molecules into smaller molecules Vocab 1. Enzymes- a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction 2. Molecules- a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction 3. Disintegrate- break up into small parts
  18. 18. chloroplasts Chloroplast is a plastid that contains chlorophyll and in which photosynthesis takes place. Location- eukaryotic cells( only plants) Function- uses energy from sun to make food for the plant (photosynthesis) Vocab 1. Photosynthesis- the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water 2. Chlorophyll- a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis 3. Plastid- any of a class of small organelles, such as chloroplasts, in the cytoplasm of plant cells, containing pigment or food.
  19. 19. Cilium Cilium is a short, microscopic, hair like vibrating structure location- outside a eukaryotic cell Function- to help move the cell around Vocab 1. Microscopic- being so small that it cant be seen with a naked eye
  20. 20. Flagellum Flagellum is a slender threadlike structure, esp. a microscopic whip like appendage that enables many protozoa, bacteria, sperm atozoa Location- on the outside of a prokaryotic cell Function- to help prokaryotes move around
