Cell Organelle Quiz Flashcards
Has a selectively permeable membrane that only allows certain substances to pass through
Cell membrane
Direct cell organelle activity; separated from cytoplasm by its own membrane; contains genetic material (DNA)
Nucleus
Surrounds nucleus; openings allow materials to enter and leave nucleus
Nuclear membrane
Found in nucleus; made of DNA which contain genes; contain instructions for traits and characteristics
Chromosomes
Inside nucleus; helps synthesize RNA that form ribosomes which help to synthesize and build proteins
Nucleolus
Gel like substances inside the cell membrane; helps the cell thrive and function; contains floating organelles
Cytoplasm
Lacks ribosomes; sythesizes lipid, phospholipids, and steroids
Smooth ER
Ribosomes embedded in the surface; synthesize proteins
Rough ER
Make proteins and produce substances needed for cell repair, movement, and reproduction; embedded in rough ER and floating in cell in cytoplasm
Ribosomes
Power plant of cell; provide energy for cell repair, movement, and reproduction; control level of water
Mitochondria
Receive proteins from rough ER; helps move materials within and out of the cell
Golgi bodies
Contain powerful enzymes that clean up intercellular debris and waste; destroy harmful materials; act as digestive system-break down materials
Lysosomes
