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 are complex, but there are differences

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

Life Functions Nutrition – to take in food Transport – to move materials Cell respiration – Make Energy: ATP Excretion – to get rid of waste Synthesis – to build, to make Regulation – to control Growth – to increase in size Reproduction – to make offspring

Do Now Define: Homeostasis Cellular Respiration

Aim: What are the various functions of an organelle?

TRANSPORT CELL MEMBRANE Barrier to protect the cell. FUNCTION: TRANSPORT Barrier to protect the cell. Controls what comes in and out.

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

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

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

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

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

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

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

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

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

REGULATION NUCLEUS Found in eukaryotic cells only! Function: Controls most cell processes and contains the hereditary information - DNA (THE BRAIN) REGULATION THE BRAIN

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

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