7.3 Structures and Organelles Chapter 7 Cellular Structure and Function 7.3 Structures and Organelles

Cell Membrane Isolates and protects the inside of a cell

Inside the Cell Membrane

Cytoplasm Cytoplasm: “Cell fluid” found inside of the cell membrane and contains the organelles

Cytoskeleton Cytoskeleton: variety of fibers and filaments that support cell structure and drive cell movement Both microtubules and microfilaments are part of the cytoskeleton

Microtubules Microtubules: Hollow tubes made of proteins Assist with movement for one-celled organisms

Microtubules (green)

Microfilaments Microfilaments: Also assist with movement Ex. Responsible for muscle cells contractions

Microfilaments

Microtubules and Microfilaments

Nucleus Nucleus: The control center of the cell Why?

Contains the DNA—molecule that contains gene and protein information DNA forms chromatin, which becomes chromosomes (genetic information) Contains the nucleolus—assembles ribosomes

Nucleus

Endoplasmic Reticulum (ER) Endoplasmic Reticulum (ER): a system of membranes that provide channels to move proteins and chemicals through the cell (think transport) Rough ER: has ribosomes attached Smooth ER: no ribosomes

Ribosomes Ribosomes: Tiny particles made up RNA and protein Hundreds to thousands per cell (most numerous organelle)

Make proteins (puts amino acids together) Some are attached to organelles others are found free in the cytoplasm

Ribosome

Mitochondria Mitochondria: The center of cellular respiration Contains enzymes that split organic molecules and release energy to be used by the cell Cell’s energy powerhouse

Mitochondria

Lysosomes Lysosomes: Sac-like membranes filled with enzymes that break down substances within the cells Cell’s clean up crew

Golgi Apparatus Golgi Apparatus: Modifies and packages proteins for future use May attach carbohydrates or lipids to a protein Customizes proteins for use

Golgi Apparatus

ER and the Golgi Apparatus

Vacuoles Vacuoles: Fluid-filled cavities or sacs used for storage In animal cells —store proteins, fats, carbs

Unicellular animals —act as a pump that removes excess water and for motion (contractile vacuole)

Contractile Vacuole

Vacuole In plants —stores water and salts

Cell Wall Found only in plants!! Provides protection and support Very rigid

Cell Wall

Plastids Plastids: storage organelles found only in plants! Three types: Chloroplasts Leucoplasts Chromoplasts

Chloroplasts (Type of Plastid) Plants Only!! Stores food and pigment Provide the green color of leaves Important with photosynthesis

Chloroplasts

Chloroplasts

Other Plastids Other Plastids: All store food and pigment Leucoplasts: stores starch Appear white under the microscope Example: potatoes, turnips

leucoplasts

Chromoplasts: stores pigments Ex. Red and orange colors in tomatoes
