Name 5 parts of an animal cell.
Cell membrane, mitochondria, ribosomes, nucleus, cytoplasm
Name 6 parts of a bacterial cell.
Cell membrane, bacterial DNA, cell wall, cytoplasm, plasmids, flagellum
Name 8 parts of a plant cell.
Cell membrane, cell wall, permanent vacuole, chloroplasts, ribosomes, cytoplasm, mitochondria, nucleus
What are plasmids?
Small, circular hoops of DNA found free in the cytoplasm and separate from the main DNA
What do plasmids do?
Carry genes that provide genetic advantages, e.g: antibiotic resistance
What does the permanent vacuole contain?
Cell sap
What is cell sap?
A solution of salts, sugars and organic acids
What is the function of the cell membrane?
It controls the entry and exit of materials in and out of the cell
What is the function of the mitochondria?
It's the site of the later stages of aerobic respiration in which ATP is produced
What is the function of the ribosomes?
They join amino acids in a specific order during translation for the synthesis of proteins
What is the structure of the cytoplasm?
It is the fluid component of the cell, it contains organelles, enzymes and dissolved ions and nutrients
What is the function of the cytoplasm?
It is the site for cellular reaction, e.g: the first stage of respiration, its the transport medium
What is the purpose of a cell wall?
It supports and strengthens the cell and is made of cellulose
What does the permanent vacuole do?
It keeps the cell turgid and contains sugars and salts in solution
What is the purpose of a nucleus?
It contains genetic material and controls the activities of the cell and codes for proteins
What is the difference between a eukaryote and a prokaryote?
A prokaryote is a bacterial cell and a eukaryote is a plant and animal cell
Name 3 differences between eukaryotes and prokaryotes.
Prokaryotes are smaller, eukaryotes contain cell membrane bound organelles and a nucleus containing genetic information
How is genetic information stored in a prokaryote?
It is found free as plasmid DNA or chromosomal DNA (a single loop of circular DNA)
What is a chloroplast?
An organelle containing chlorophyll which absorbs light for photosynthesis
What is the function of a chloroplast?
It is the site of photosynthesis
