8 Organelles

Endoplasmic Reticulum

-Folded membranes forming tubes and canals -Transports materials throughout a cell

Ribosomes

-Made in the nucleus -Small round dark organelles found in the cytoplasm and on rough ER -Makes proteins for the cell

Nucleus

-Round or oval, found in the center of a cell, often dark -Surrounded by a nuclear membrane (nuclear envelope) with nuclear pores -Contains chromosomes (DNA) -Controls cell functions and reproduction -Can contain a nucleus (which makes the ribosomes)

Mitochondria

-Round or ovals pods with long inner folded membranes -Provide energy for a cell by releasing the energy into food

Lysosomes

-Small sacs -Contain chemicals that break down food, waste or old cell parts -Ex: absorption of tadpole tales

Organelles

-Special tiny parts, floating in the cytoplasm -Each has a specific form and function (shape and job) -They carry out all life processes

Golgi Bodies

-Stacks of flattened membrane sacs -Receive materials, repackage and distribute to other parts of the cell

Rough ER

-does have ribosomes

Chloroplasts

-large organelles found in plant cells -green from chlorphyll -trap energy from sun, convert it to food (photosynthesis)

Smooth ER

-no ribosomes

Vacuoles

Sacs of storage for different substances -Food vacuoles -Water vacuoles -Waste vacuoles In plants, mature cells have a Central Vacuole (contains sap, amino acids, pigments and sugars)
