responsible for synthesizing proteins
has a smooth appearance
take lipid building blocks and assembles fats (animal cells) and oils (palnt cells)
What is true about Ribosomes?
granules attached to the Rough ER, or present in the cytoplasm.
take amino acid building blocks and assemble them into proteins (it's the place for protein synthesis)
The ribosomes have no membrane
granules attached to the Smooth ER, or present in the cytoplasm.
What are the lysosomes?
membrane-bound sacs containing strong digestive enzymes
kill invading bacteria and destroy damaged cell organelles
if a cell malfunctions, its lysosomes will burst and kill the cell before an infection spreads
sometimes called suicide sacs
What are chloroplasts?
found only in plants
contain a green pigment called chlorophyll
site of photosynthesis
converts the sun's energy into glucose and water
What is true about Mitochondria?
It's the site of cellular respiration
chemical energy (glucose) is converted into usable energy for the cell
cells with higher energy needs(e.g. muscle cells, sperm cells) are packed with mitochondria
cells with lower energy needs(e.g. muscle cells, sperm cells) are packed with mitochondria
