Section 7: CELL STRUCTURE AND FUNCTION

Slide 2

California State Standards 1. Cell science Cells are encased in semipermeable layers that control their collaborations with their environment Know prokaryotic cell vary from eukaryotic cells Know the part of endoplasmic reticulum and golgi mechanical assembly in the discharge of proteins Students know the part of mitochondria in making put away synthetic bond vitality accessible to cells j. Understudies know how eukaryotic cells are given shape and inner association by a cytoskeleton or cell divider or both.

The Cell Theory Mathias Schleiden-Theodor Schwann-Rudolf Virchow-Observed little living things in lake water Concluded all plants are made of cells Stated all creatures are made of cells Concluded new cells originate from existing cells

Slide 4

Cell Theory : cells  All living things are made out of _____  Cells are the essential units of structure and capacity in living things  New cells are delivered from ____________ Existing cells

Slide 8

Eukaryotic Cell versus Prokaryotic cell

Slide 9

Warm-up Section 7-1 Name 3 researchers and their commitment to science. What is the cell hypothesis? What are the attributes of prokaryotes and eukaryotes. Utilize the "reasoning outwardly" box on page 173 to answer this question.

Slide 14

Warm-up Section 7-2 Compare and complexity plant and creature cells. It is safe to say that they are prokaryotic or eukaryotic? Eukaryotic cells keep up shape and interior association with … .? What is the capacity of the core? Where is compound vitality from sustenance changed over to useable vitality? Where is light vitality changed over to synthetic vitality in plants? What is this procedure called?

enters leaves 7-3 Cell Boundaries A. Cell Membrane Regulates what ___________ and __________ the cell Provides Composed of a ______________ __________________ are implanted in the bilayer; _________________ are appended to a portion of the proteins; permits cells to __________ each other. assurance and bolster lipid bilayer Protein particles frame channels and pumps to move material over the cell film. Starches recognize

Slide 16

Outside of cell Carbohydrate chains Proteins Cell film Inside of cell (cytoplasm) Protein channel Lipid bilayer CELL MEMBRANE "Liquid MOSAIC" "ID labels" "transport" "Phospholipids"

Slide 17

plants, green growth, parasites and numerous prokaryotes Cell Walls Found in Cell dividers are sufficiently permeable to permit Main capacity is to give Plant cell dividers made of __________ (sugar fiber) water, oxygen, carbon dioxide effectively support and insurance for the cell cellulose

Slide 18

C. Dissemination Through Cell Boundaries All living cells exists in a Cell layers direct Cell films are _____________________ (otherwise known as: _______________) If substances can pass, then the cell layer = If substances can't pass, then the cell membrane= fluid condition. the development of particles all through the cell. specifically porous semipermeable Permeable impermeable

Slide 19

Water and different substances between the phone layer and the core. 1. Measuring Concentration Cytoplasm= Concentration= Example:12g salt/3L H2O= 60g salt/3L H2O= Concentration gradient= mass of solute/volume of arrangement 4 g/L 20 g/L 5X more thought unequal dissemination of particles

Slide 20

impact and spread out haphazardly in arrangement high to low 2. Dispersion Particles continually Particles move from a _____ fixation _____ a ____ focus (with the focus angle); process is known as _________ Diffusion proceeds until Equilibrium =  Diffusion relies on irregular molecule developments, substances diffuse crosswise over layers ______ requiring the phone to utilize _______ dissemination balance is achieved When particles are uniformly circulated in arrangement without vitality The development of particles will keep on moving similarly over the phone film to look after balance.

Slide 21

H 2 O passes effortlessly crosswise over most layers The dissemination of water through a specifically penetrable film Osmosis  Osmosis = Before Osmosis After Osmosis Selectively porous film water solute

Slide 22

1. How Osmosis Works Left Beaker: More sugar particles on the ____ side (low water focus). The layer is penetrable to water yet not sugar. left High water focus on the correct side. Net development of water from high water fixation to low water focus.

Slide 23

TYPES OF SOLUTIONS Hypertonic Solution Isotonic Solution Hypotonic Solution "above strength" "same strength" "underneath quality" High convergence of Equal centralization of Low grouping of Dissolved substances disintegrated substances broke up substances In Solution in arrangement

Slide 24

Cells in a hypertonic arrangement In a hypertonic arrangement, water leaves a cell by osmosis, bringing on the phone to recoil. H 2 O H 2 O Water Molecule Dissolved Molecule

Slide 25

Cells in a hypotonic arrangement In a hypotonic arrangement, water enters a cell by osmosis, bringing about the phone to swell. H 2 O H 2 O Water Molecule Dissolved Molecule

Slide 26

Cells in an isotonic arrangement In an isotonic arrangement , the centralization of broke up substances in the arrangement is the same as the grouping of disintegrated substances inside the cell. H 2 O H 2 O Water Molecule Dissolved Molecule

Slide 27

The impacts of Osmosis on cells (creature cells allude to figure 7-16) Cells in a hypertonic arrangement Cells in a hypotonic arrangement Cells in an isotonic arrangement

Slide 28

With the assistance of protein channels E. Encouraged Diffusion Molecules, that can't diffuse over the cell film's lipid bilayer all alone, can move Molecules still ___________________ focus move from high to low

Slide 29

Molecule to be conveyed Energy Molecule being conveyed against a fixation angle (from low to high) vitality F. Dynamic Transport Movement of particles Requires Needs a vehicle protein or pump

Slide 30

Large atoms and clusters of material can be taken into the cell by a procedure known as ___________. The two sorts of endocytosis are: 1. Phagocytosis= 2. Pinocytosis= ___________= arrival of a lot of material endocytosis 'Cell eating' 'cell drinking' Exocytosis endo/exocytosis exhibition

Slide 31

Transport of Large Particles Section 8.1 Summary – pages 195 - 200 Endocytosis is a procedure by which a cell encompasses and takes in material from its condition. Core Digestion Exocytosis Endocytosis Wastes expulsion

Slide 32

Let's Review: intuitive destinations for cell film, dispersion, dynamic, latent transport Simple dissemination (incorporates Osmosis) Facilitated Diffusion ATP required No ATP No ATP Hi-Lo Hi Lo-Hi No protein Needs protein Needs Protein

Slide 33

Warm-up Section 7-3 Describe the life systems of a cell layer. What are the fundamental elements of the cell film and the cell divider? What occurs amid dispersion? What is osmosis? Portray the terms hypotonic, hypertonic, isotonic. Thoroughly analyze latent and dynamic transport.

Slide 34

Multicellular Organisms (numerous celled) Cells get to be ___________ to perform distinctive assignments Cells need to impart and participate Yeast, green growth, microbes specific

Slide 35

C. Levels of Organization  The levels of association in a multicellular life form are: singular CELLS TISSUES ORGANS ORGAN SYSTEMS

Slide 36

Group of comparable cells that play out a specific capacity muscle epithelial 1. Tissues= Four sorts of tissue: - Organs= Ex. bicep muscle is distraught of muscle, connective, and sensory tissue 3. Organ Systems= anxious connective Groups of tissues Group of organs that cooperate to play out a particular capacity.

Slide 37
