8. Day 3 Sec 7.3—Eukaryotic Cell Structure

9. Plant Cells Compared with Animal Cells Both plant and animal cells are eukaryotic cells, but the structures of both types of cells have major differences. Animal cells do not have a cell wall. Instead of a cell wall, the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Plant cells have both a cell wall and a plasma membrane. Animal tissues therefore require either external or internal support from some kind of skeleton, known as the cytoskeleton. Centrioles are generally not found in plant cells, while they are found in animal cells. Animal cells do not have chloroplasts, but they are common in plant cells because plants make their own food through the process of photosynthesis. Both cell types have vacuoles, however, in animal cells vacuoles are very tiny, while in plant cells vacuoles are generally quite large. In many types of plant cells, particularly in species like conifers and flowering plants, there is an absence of flagellae and centrioles that are found in animal cells. There is another major difference between plant and animal cells. While the former turn carbon dioxide into sugar, it is the animal cells that break the sugar back down to carbon dioxide to make energy.eukaryoticspecies like coniferscarbon dioxide Make Venn Diagram with Partner!

13. Nucleus Nucleolus Control Location: In the center of the cell Function: Controls all cellular functions

14. Protect and Support Cell Wall Location: Outside wall of cell Function: Supports and protects plant cells

15. Protect and Support Cytoplasm Location: Fluid inside, Fills all space besides organelles Function: Jelly-like fluid inside cell; holds organelles

16. Protect and Support Cytoskeleton Location: In the cytoplasm Function: Forms a frame for the cell for support

17. Assembly, Transport, Storage Plasma Membrane Location: Surrounds the cell on the outside Function: Allows substances to pass in and out of cell

18. Assembly, Transport, Storage Endoplasmic Reticulum Function: Place where chemical reactions occur Location: In the cytoplasm

19. Assembly, Transport, Storage Ribosomes Location: On the ER or floating freely in the cytoplasm Function: Make proteins

20. Assembly, Transport, Storage Golgi Apparatus vesicle Function: Packages and transports proteins Location: In the cytoplasm

21. Assembly, Transport, Storage Animal Cell = very small vacuoles Plant Cell=very large vacuole Vacuole Location: Plant: in the center of cytoplasm Animal: small in cytplasm Function: Stores enzymes and wastes

22. Recycling Lysosomes Function: Digest foreign materials and old organelles Location: In the cytoplasm

23. Energy Transformers Mitochondria Function: Provides energy for cells, cells that need more energy have more mitochondria Location: In the cytoplasm

24. Energy Transformers Chloroplast Location: in the cytoplasm Function: Transforms light energy into chemical energy (provides food)

25. Movement Cilia Flagella Location: outside of cell on cell surface Function: Aids in cell movement and feeding

26. Objectives: I CAN… □ Compare and contrast animal cells and plant cells □ Identify the main organelles in the cell and their functions.
