Unit 2.1d: Specialisation Of Cells Flashcards
What is the structure and function of a nerve cell?
Long connection length for transmitting signals over long distance from sensors to the brain
What is the structure and function a red blood cell?
Has biconcave shape and no nucleus giving large surface area so it can carry more oxygen
What is the structure and function of a sperm cell?
Has a tail to swim to the egg and fertilise the egg
What is the structure and function of a root hair cell?
Long and thin so it has a large surface area to absorb more water
What is the structure and function of a leaf palisade cell?
Has many chloroplasts to carry out photosynthesis
What is the structure and function of a ciliated cell?
Lines cavities e.g. airways and oviduct. Has tiny hairs to help move dirt out of lungs and move eggs along oviduct
What are tissues made up of?
Many copies of a specialised cell type e.g a muscle is made up of many muscle cells
What do different tissue types combine to make?
An organ e.g a heart is made up of both muscle tissue and nerve tissue
What do organs work together to form?
A system e.g The heart, blood vessels and the blood all form the cardiovascular system
What is stage 1 of cellular organisation in animals?
Cellular level (muscle cell)
What is stage 2 of cellular organisation in animals?
Tissue level (muscle tissue)
What is stage 3 of cellular organisation in animals?
Organ level (heart)
What are multicellular organisms made up of?
Many different cell types
What is the hierarchy of cell types in multicellular organisms?
Tissues, organs, and organ systems
What is stage 4 of cellular organisation in animals
Organ system level (cardiovascular system)
