Cell Structure Organelles
B. Organelles (little organs) 1. Control a. Nucleus -contains genetic material -stores DNA -surrounded by a double membrane with pores -directs all cell activities -contains the nucleolus
2. Energy Related i. Chloroplast (in plants only) -Green -Contains pigment chlorophyll -Site of photosynthesis
2. Energy Related (cont.) b. Mitochondria - “powerhouse of the cell” - Site of cellular respiration - Where ATP is formed
3. Membranous Sacs & Canals a. Endoplasmic reticulum (ER) -miniature circulatory system -series of tubular canals -serves to transport materials Smooth ER- transports lipids Rough ER-transports proteins
b. Ribosomes -small spherical structures -made of RNA -site of Protein Synthesis -may be free (in cytoplasm) or -attached (on the rough ER)
c. Vacuole -sac -used for storage (food, water, etc.) -1 large in all plants, - several small in only some animals
d. Lysosome -storage sac -contains digestive enzymes - “suicide bag” Ex. Membranes present between fingers and toes in early embryos
e. Golgi Body (Complex/Apparatus) -series of flattened sacs (disc-like) -packages cell secretions (products) Ex. Goblet Cell & Mucous
4. Cytoskeleton & Movement -give support and internal structure to cell -aid in moving organelles (form a track) -give support & internal structure to cell -important in muscle cell contraction
d. Flagellum -only on animal cells -long hair-like projection in whip-like motion -used to propel the cell -made of microtubules
e. Cilia -only in animal cells -used to propel cells (uses an oar-like motion) -used in organisms to move materials Ex. Line respiratory tract and move debris move egg cells down the fallopian tube
Plant vs. Animal Cells Cell wall Rigid shape Chloroplasts 1 large vacuole Lacks cell wall Flexible shape No chloroplasts Several small vacuoles Cilia & flagella may be present
Important Terms: eukaryotic cell: cells that contain nuclei and more complex organelles Ex: nerve cells; amoeba prokaryotic cells: cells that lack a nucleus.
Cell Organelles. Plant Cell Animal Cell Cell Boundaries 1)Plasma Membrane – semi-permeable membrane 2)Cell Wall -Plants, Fungi, and Bacteria have this.
Golgi apparatus Flat organelle Stores proteins to be distributed Pancake shaped layers.
Cellular Parts S7L2b Relate cell structure (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions.

Cell Organelles. 3-2 Animal cell anatomy 3-3 Plant cell anatomy.
4A Cell Organelles specialized structures within a living cell.
Nucleus/Nucleolus Structure Function Cell Type
HOW WELL DO YOU KNOW THE CELL?. NUCLEUS Contains DNA – genetic material of the cell 2 membranes surrounding it, the envelope/membrane Controls all of.
2.02 Structure and Function of Cells Cells are the basic unit of structure for all living things.
Cell structure – form and function. The cell as a factory The nucleus.
Organelle Structures. Lysosome Contains digestive enzymes that break down molecules.
CYTOPLASM/CYTOSOL Structure Function Cell Type
Structures and Organelles Objectives Identify parts of eukaryotic cell Compare plant and animal cells.
Plant and Animal Cell Structures
Cell and Their Organelles
Nucleus/Nucleolus Structure Double membrane (nuclear envelope) with nuclear pores Chromatin Nucleolus Function Stores hereditary info (DNA)
Structures and Organelles 7.3. Cytoplasm and Cytoskeleton Cytoplasm-semifluid material prokaryotes- Chemical process occur eukaryotes- Where organelles.
Cell Structure and Function
Cells and all that Jazz H. Smith. Cell Theory: 3 parts Cells are the basic unit of life. All living things are made of cells. All cells come from pre-existing.
Cell Organelles Found in Plant and Animal Cells Cell membrane Nucleus Nucleolus Mitochonria Ribosomes Lysosomes Endoplasmic reticulum Golgi Body Cilia.
Cell Structures and Organelles. Cell Membrane Found: All Cells Location: Outer part of the cell Structure: Phospholipid bilayer Fluid, flexible Function/
PLANT AND ANIMAL CELLS.
Basic Cell Structure.
Eukaryotic Cells Animal and Plant. Cell/Plasma Membrane Thin covering that surrounds the cell Controls movement of materials in and out of cell.
KEY CONCEPT Eukaryotic cells share many similarities.

Cell Organelles Section 7.3. Cell Wall Found outside some cell membranes It provides support and protection Made of cellulose.
Basic Structure of a Eukaryotic Cell Eukaryotic Cell Contain 3 basic cell structures: Nucleus Cell Membrane Cytoplasm with organelles There are 2 main.

Cell Organelles Chapter 7 – Section 3.
Chapter 3 Cell Structure and Function. Animal Cell 1. cell (plasma) membrane – thin, transparent, 2-layered, semi-permeable (porous), flexible -controls.
ANIMAL AND PLANT CELLS CELLS – The building blocks of all living things. Only visible with a microscope!
