1 Warm-Up Answer the following questions in a complete sentence and explain why each answer is correct. Unlike a eukaryotic cell, a prokaryotic does not have A. DNA. B. a cell membrane. C. cytoplasm. D. a nucleus. Unlike a eukaryotic cell, a prokaryotic cell does not have because Identify the type of cell depicted below. A. prokaryotic B. eukaryotic C. bacterial D. virus The type of cell depicted is a Because

2 Review Endosymbiosis This is the endosymbiotic theory, or the theory that the chloroplast and mitochondria came from living bacteria. Evidence: In both mitochondria and chloroplast we see DNA Ribosomes Double Membrane

3 Review - Eukaryotic Cells UNIT 5 The first cells (bacteria) were prokaryotic. They are the most basic cells. When one cell engulfed another cell, it became eukaryotic. Eukaryotic cells are more organized because they have membrane bound organelles (compartments).

4 Review - Prokaryote vs. Eukaryote PRO means NO! No nucleus or no membrane bound organelles Prokaryote or Eukaryote? Has ribosomes Bacteria Plant Cell Can work together to make a large organism Has DNA Has membrane-bound organelles Has Mitochondria Has a cell membrane Is killed by antibiotics Animal Cell Has no membrane-bound organelles Is a living organism

5 Animal Cell (Eukaryote) UNIT 5 Cell Membrane Vacuole Nucleus Nucleolus Nuclear Envelope Lysosome Mitochondria Cytoplasm Rough ER Smooth ER Ribosomes Golgi Body Eukaryotic cell membrane only Mutlicellular Mitochondria only Multiple smaller vacuoles

6 How do animal cells get their energy?

7 Mitochondria Animal cells have the organelle mitochondria Site of cellular respiration (making of ATP) ATP= Energy molecule

8 Plant Cell (Eukaryote) UNIT 5 Cell Wall Cell Membrane Cytoplasm Lysosome Vacuole Nucleus Nucleolus Rough ER Smooth ER Nuclear Envelope Chloroplast Mitochondria Ribosomes Golgi Body

9 Plant Cells Plant cells are eukaryotic and have all of the organelles as animal cells, plus: UNIT 5

10 Plant Cells Plant cells are eukaryotic and have all of the organelles as animal cells, plus: Chloroplasts (make sugar during photosynthesis) UNIT 5

11 Plant Cells Plant cells are eukaryotic and have all of the organelles as animal cells, plus: Chloroplasts (make sugar during photosynthesis) How do plants stay upright if they don t have skeletons? UNIT 5

12 Plant Cells Plant cells are eukaryotic and have all of the organelles as animal cells, plus: Chloroplasts (make sugar during photosynthesis) Cell Walls (protects the cell and keeps it rigid) UNIT 5

13 Plant Cells Plant cells are eukaryotic and have all of the organelles as If animal plant cells, cells plus: are rigid, do Chloroplasts they explode (make sugar when during they photosynthesis) take in too Cell Walls (protects the cell much water? and keeps it rigid) Vacuole (stores water) UNIT 5

14 Plant Cells Plant cells are eukaryotic and have all of the organelles as animal cells, plus: Chloroplasts (make sugar during photosynthesis) Cell Walls (protects the cell and keeps it rigid) Large Central Vacuole (stores water) UNIT 5 vacuole

15 How do plant cells get their energy?

16 Chloroplast Plant cells have the organelle chloroplast. Site of photosynthesis (making of glucose) Glucose will act as food Glucose Glucose

17 Plant or Animal Cell? Or Both? Has a nucleus Performs cellular respiration Has ribosomes Performs photosynthesis Has membrane-bound organelles Autotroph Has a cell membrane Has a vacuole Has a chloroplast Makes ATP Makes glucose Has DNA Has a cell wall Has mitochondria Heterotroph

18 Organelle Cut & Paste Activity Match the function cards and memory cards by gluing them into the correct locations in the chart. Glue in your notebook when finished.

19

20 Closure How is the process by which plants obtain energy different from that of animals? In what organelle does this occur? Plants obtain energy by, which occurs in.. Whereas animals obtain energy by which occurs in
