Aim: How can we describe the structure and function of cell organelles?

ORGANIZATION CHART BACTERIA

Prokaryotes All Bacteria They DO NOT have membrane bound organelles. They DO have: Cell Membranes Cell Walls DNA Ribosomes

2 Types of Eukaryotic Cells: Animal Cell Plant Cell Both complex, but with differences.

What things are inside the cell? Organelles - Specialized structures in cells that perform important cellular functions.

Organization of Structure of Multi-celled Organisms ORGANS SYSTEM ORGAN TISSUE CELL ORGANELLE

Life Functions Nutrition – to get nutrients for energy Transport – to move materials from A to B Cell respiration – Energy: ATP Excretion – to get rid of metabolic waste Synthesis – to build, to make Regulation – to control Growth – to increase in size or number Reproduction – to make offspring

Aim: What are the various functions of an organelle?

TRANSPORT CELL MEMBRANE FUNCTION: Provides boundary of the cell. Controls what comes in and out.

TRANSPORT CYTOPLASM FUNCTION: To protect and support the organelles within the cell. Aids in transport within cell TRANSPORT

*REGULATION *Synthesis *Reproduction NUCLEUS Found in eukaryotic cells only! Function: Controls most cell processes and contains the hereditary information - DNA *REGULATION *Synthesis *Reproduction

ENDOPLASMIC RETICULUM FUNCTION Transportation route of cell. Materials travel through it. 2 Types: Rough ER (has ribosomes) & Smooth ER TRANSPORT

SYNTHESIS RIBOSOMES FUNCTION: They FORM proteins Can be found in cytoplasm or on Endoplasmic Reticulum (Rough)

TRANSPORT GOLGI APPARATUS FUNCTION: Proteins from ER come here. Labels and packages the proteins, gives them a direction to follow. TRANSPORT

RESPIRATION MITOCHONDRIA FUNCTION: “Powerhouse of the cell.” Makes energy or ATP from food and oxygen. RESPIRATION

NUTRITION LYSOSOMES FUNCTION: Contain enzymes that can break down nutrients. Also they break down dead organelles.

EXCRETION VACUOLES FUNCTION: Store materials such as water, salt, proteins, & carbohydrates. MANY SMALL ONES IN ANIMAL CELLS, AND ONE BIG ONE IN PLANT CELLS. EXCRETION

REPRODUCTION CENTRIOLES FUNCTION: FOUND ONLY IN ANIMAL CELLS Involved in animal cell division FOUND ONLY IN ANIMAL CELLS REPRODUCTION

SYNTHESIS & Autotrophic Nutrition CHLOROPLASTS FUNCTION: SYNTHESIS & Autotrophic Nutrition Use energy from sunlight to make energy-rich food molecules in a process known as PHOTOSYNTHESIS FOUND IN PLANT CELLS!

SUPPORT & PROTECTION CELL WALL FUNCTION: Provides support and protection for the cell and allows materials in and out of the cell. FOUND IN PLANT CELLS. SUPPORT & PROTECTION

NUTRITION & LOCOMOTION CILIA & FLAGELLA FUNCTION: Made of protein and help with the movement of individual cells NUTRITION & LOCOMOTION
