Biology: Cells and Cell Functions
Questions and Answers.
prokaryotic cells - Answer Characteristics:
No nucleus
Bacteria
eukaryotic cells - Answer Characteristics:
Nucleus
Animals, Plants, Fungi, & Protists
organelles - Answer small structures in the cytoplasm that do special jobs
Ex: ribosomes, mitochondria, lysosomes, etc.
ribosome - Answer a cell organelle composed of RNA and protein; the site of protein
synthesis
golgi apparatus - Answer stack of membranes in the cell that modifies, sorts, and packages
proteins from the endoplasmic reticulum
vacuole - Answer storage structures for food, water, minerals, waste...usually plants have
one larger vacuole while animals have many small ones located throughout cell
smooth endoplasmic reticulum - Answer A network of interconnected membranes forming
channels within the cell.
Function: Transportation System; Synthesis of lipids; Breaks down toxins
rough endoplasmic reticulum - Answer System of internal membranes within the cytoplasm.
Membranes are rough due to the presence of ribosomes. functions in transport of substances
such as proteins within the cytoplasm
nucleus - Answer Brain and control center of cell: contains DNA
cell wall - Answer rigid outer laryer of cell, provides support and helps maintain shape of cell
cell membrane - Answer thin, flexible barrier around a cell; regulates what enters and leaves
the cell
