CELL ORGANELLES AND MEMBRANE FLASHCARDS

What does the nucleus do?

Holds DNA

What does the Rough ER do?

LOCATION proteins are made

What do ribosomes do?

Reads DNA and makes proteins

What happens in the Golgi?

Sorts/packages products made in the cell

What do lysosomes do?

Removes waste

What do secretory vesicles do?

Moves good material from Golgi out of cell

What do the mitochondria do?

Creates cell energy (ATP)

What do chloroplasts do?

Photosynthesis

What is the function of a vacuole?

Food/water reservoir

What is the function of cytoskeleton?

Gives the cell shape and strength

What do cilia do?

Short hairs that move things past the cell

What do flagella do?

They move the entire cell

Plasma membrane

Flexible boundary separating cell from outside world

Selective permeability

A cell can choose what enters and exits

Phosphate heads

Water attracting part of membrane

Lipid tails

Water repelling part of membrane

Cholesterol

Coats lipid tails so they don’t stick

Carbohydrates

Communicates outside surroundings to nucleus

Proteins

Channels that open up to allow large things through the membrane

Passive transport

Moves molecules from high to low

Active transport

Moves molecules from low to high; requires energy

Diffusion

Movement of any molecules from high to low
