Organisation
The smallest level of organisation
Cells
Bacteria is a type of ?
Prokaryote
Provides energy for the cell
Mitochondrion/a
Type of cell which contracts, helping to move parts of the body
Muscle cell
Upper chambers of the heart
Atrium
An organ consists of different types of ?
Tissues
Humans are a type of ?
Eukaryote
Control centre of the cell
Nucleus
Send electrical signals throughout the body
Nerves
Type of blood vessel which carries blood toward the heart
Vein
The bigger one; red blood cell or egg cell
Egg cell
Organelle which prokaryotes lack
Nucleus / membrane-bound organelles
The difference between smooth and rough ER
Ribosomes
Organelle which muscle cells have a lot of to perform their function
Mitochondria
Septum
An example of a unicellular organism
Bacteria, yeast, amoeba, paramecium
Both prokaryotes and eukaryotes have
Ribosomes, cytoplasm, cell membrane, cell wall (plant cell)
Compared to a plant cell, an animal cell does NOT contain
Chloroplasts, cell wall, large vacuole
System which white blood cells mainly apart of
Immune system
Purpose of valves
Prevent backflow of blood
Body system which works closely with the circulatory system to oxygenate the blood
Respiratory system
Difference between nucleoid and nucleus
non membrane-bound genetic material floating in the cytoplasm vs membrane-bound spherical organelle containing genetic info
,
Modifies, sorts and packages proteins
Golgi apparatus
Difference in the structure of a root hair cell vs a palisade (leaf) cell
Root cell = larger surface area to absorb water, no chloroplasts. Palisade cell = thin, lots of chloroplasts for photosynthesis
Blood vessel with high pressure and thick elastic walls which carries blood away from the left ventricle
Aorta / Aortic artery
