1 Cells: Plants and Animals

2 1.Overview of Cells 2.Differences Between Plant and Animal Cells 3.Cells Organization within the Body 4.Tissue Overview Cells: Plants and Animals

3 Cells in cork walled boxes that are similar to tiny rooms, or cellula, occupied by monks = "cell.“ Cells in a  plant How Cells Were Named Cells in an animal 

4 Cell Size

5 Cells Contain Organelles

6 Comparing Animal and Plant Cells Animal Cell Plant Cell Variety of Shapes One or more small vacuoles Centrioles Lysosomes Often have cilia or flagella Cell Membrane Cytoplasm ER (smooth and rough) Ribosomes Mitochondria Golgi apparatus Nucleus Cell Wall Rectangular One large, central vacuole Plastids Chloroplasts Rarely have cilia or flagella

7 Comparing Animal and Plant Cells Animal Cell Plant Cell Variety of Shapes One or more small vacuoles Centrioles Lysosomes Often have cilia or flagella Cell Membrane Cytoplasm Nucleus Mitochondria Endoplasmic Reticulum Golgi Apparatus Cell Wall Rectangular One large, central vacuole Plastids Chloroplasts Rarely have cilia or flagella

8 Animal Cell

9 Plant Cell

10 Double layer of phospholipids controls the flow of water Animal Cell

11 Cell Membrane Electron Microscope Image of Rickettsia felis Animal Cells

12 Cell Membrane Electron Microscope Image of a Pollen Tube of an Orange Bush Monkey Flower Plant Cell

13 Animal Cell Plant Cell Surrounded by double membrane Holds DNA Involved in cell division

14 Nucleus Electron Microscope Image of a White Blood Cell Animal Cell

15 Plant Cell Make energy for the cell Can be different shapes Surrounded by a double membrane

16 Mitochondrion Electron Microscope Image of a Plant Cell Plant Cell

17 Animal Cell Plant Cell Different functions depending on cell type Produces chemicals for the cell Controls the release of ions Collects proteins

18 Endoplasmic Reticulum Electron Microscope Image of a Cartilage Cell Animal Cell

19 Plant Cell Animal Cell Surrounded with a single membrane Packages substances to be transported

23 Membrane bound sac Intracellular digestion Release of cellular waste Generally small in animal cells Animal Cell

24 Vacuoles Electron Microscope Image of a Pancreatic Cell Animal Cell

25 Part of cytoskeleton of the cell Ring of nine groups of fused microtubules Groups of three microtubles Plants do not have centrioles Animal Cell

26 Centriole Electron Microscope Image of a White Blood Cell Animal Cell

27 Contain enzymes necessary for intracellular digestion In white blood cells, these lysozymes digest bacteria Cause cell death if improperly released into cytoplasm Animal Cell

39 Cells in Perspective

40 ORGAN – Two or more types of tissues; larger functional unit e.g., skin, kidney, intestine, blood vessels Cells in Perspective TISSUE – Groups of cells with same general function and texture (texture = tissue) e.g., muscle, nerve, epithelium, and connective tis. CELL – Smallest unit, Simplest animals consist of a single cell. ORGAN SYSTEM - Several organs e.g., respiratory, digestive, reproductive systems CELL TISSUE ORGAN SYSTEM

41 FOUR BASIC TYPES OF TISSUES IN THE BODY EpitheliumConnective tissue Muscular tissue Nervous tissue

42 Functions : Cover organs, line organs, blood vessels, and secretory cells of glands Epithelium

43 Function: binds the other tissues together to form organs include blood, cartilage, and bone Connective Tissue CONNECTIVE TISSUE

44 Function: generation of contractile force Distribution: Smooth – involuntary movements of organs, respiratory tract, blood vessels, uterus, etc. Cardiac – involuntary contractions of the heart Skeletal – voluntary movements, mostly associated with the skeleton Muscle

45 Nervous Tissue Functions: transmission, reception, and integration of electrical impulses Characteristics: neurons – very large excitable cells with long processes called axons and dendrites Glial cells – the supporting cells of nervous tissue Nerves – collections of neuronal processes bound together by connective tissue
