CELL PARTS OBJ: Describe relationships between structure and function of organelles

Cytoplasm Clear, gelatinous fluid inside the cell Found in both plant and animal cells http://biology.unm.edu/ccouncil/Biology_124/Images/cytoplasm.jpeg

Organelles the “tiny organs” of a cell required for the cell to function Only present in EUKAROTES! Specific – have different jobs within the cell

12
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
14
Nucleus The control center of the cell, “the brain”
15
Nucleus Surrounded by the nuclear envelope ◦ made of two membranes ◦ this membrane has pores to allow substances in and out of the nucleus
16
Nucleus Surrounded by the nuclear envelope ◦ made of two membranes ◦ this membrane has pores to allow substances in and out of the nucleus
17
Nucleus Contains almost all of the cell’s DNA ◦ instructions for making proteins ◦ chromatin – DNA bound to a protein (IMP for cell division)
18
Nucleus The nucleolus is found in the nucleus ◦ ribosome's are assembled
19
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
21
Ribosomes Site of protein synthesis ◦ Use the instructions from DNA to make proteins Small particles of RNA and protein found all over the cytoplasm

23
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
25
Endoplasmic Reticulum (ER) – intracellular highway Where lipids are assembled in the cell, and proteins and other materials are exported from the cell
26
Endoplasmic Reticulum (ER) – intracellular highway Rough ER is dotted with ribosomes ◦ responsible for the assembly of proteins ◦ proteins leave the ribosomes after synthesis and are chemically modified in the rough ER
27
Endoplasmic Reticulum (ER) – intracellular highway Smooth ER is the outer part of the ER ◦ Does not have ribosome's attached ◦ Lipids can be synthesized ◦ Liver cells responsible for detox of the blood contains lots of smooth ER
28
ER (rough and smooth)
29
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
31
Golgi Apparatus Modifies, sorts and packages proteins from the ER for storage in the cell, or secretion out of the cell ◦ “the Post Office of the cell”
32
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
34
Lysosomes Small organelles filled with digestive enzymes Digests/breaks down old organelles, lipids, carbs, and proteins (the “junk” in the cell) Tay-Sachs disease can be linked to poorly performing lysosomes

36
Lysosomes Small organelles filled with digestive enzymes Digests/breaks down old organelles, lipids, carbs, and proteins (the “junk” in the cell) Tay-Sachs disease can be linked to poorly performing lysosomes- enzyme breaks down lipids no longer works
37
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
39
Vacuoles Cell storage (for water, food, wastes, salts, proteins, and carbs) Plant cells contain a single large vacuole…why? http://www.healthsystem.virginia.edu/internet/hematology/HessImage s/Copper-deficiency-vacuoles-100x.jpg http://education.kings.edu/dsmith/vacuole.jpg

Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
43
Mitochondria Found in both plant and animal cells Convert chemical energy from food into compounds that the cell is able to use ◦ Energy conversions ◦ called “the powerhouse” of the cell
44
Mitochondria Cellular respiration takes place in this organelle Contains its own DNA separate from that of the nucleus (could this mean that they come from ancient prokaryotes?)
45
Organelles Nucleus Ribosomes Endoplasmic Reticulum (smooth and rough) Golgi Apparatus Lysosomes Vacuole Mitochondria Chloroplasts Cytoskeleton
47
Chloroplasts Found in plant cells only! Capture energy from sunlight and convert it into chemical energy through photosynthesis Chlorophyll is found inside of these organelles Also contain their own DNA (like mitochondria) –

52
Cytoskeleton Provides the framework for the cell Made of protein filaments to help maintain shape for the eukaryotic cell (also helps with movement)
53
Cytoskeleton ◦ Microfilaments = threadlike structures made of protein ◦ Microtubules = hollow structures made of proteins (also form the spindle for cell division using the centrioles with are found only in animal cells) ◦ Centrioles = help organize cell division in animal cells

56
Cell Boundaries
58
Plasma Membrane/ Cell membrane Boundary between the cell and its environment Allows nutrients into and out of the cell as necessary ◦ (no matter what the external conditions may be) – it controls what enters and leaves
60
Cell wall Provides support and protection for the plant cell Composed mainly of cellulose (a sugar that we cannot breakdown/digest) Found only in plant cells http://www.desmids.nl/info/sheddingoftheprimarycellwall/images/Pleurotaen iumehrenbergii2.jpg
61
PLANT CELLS VERSE ANIMAL CELLS OBJ: compare and contrast plant and animal cells
62
Plant Cells Cell Wall ◦ (makes cell typically square in shape) Cell membrane AKA plasma membrane Chloroplasts/chlorophyll ◦ (gives cell green color) Large central vacuole http://micro.magnet.fsu.edu/cells/plants/images/plantcell.jpg
63
Animal Cells Cell membrane AKA plasma membrane Small vacuole No cell wall ◦ allows cell to be round in shape No chloroplasts/chlorophyll (not green in color) https://dbscience3.wikispaces.com/file/view/Animal-Cell.jpg/47335793/Animal- Cell.jpg
