Cell Structure And Organisation Flashcards
What is an organelle
Structures within the cell that help it to function
E.g. mitochondria
What is a cell
Building blocks of all organisms
E.g. Palisade cell
What is a tissue
A groups of similar cells working together to perform a specific function
E.g. Nervous tissue
What is an organ
A group of different tissues working together to perform a specific function
E.g. Eye
What is an organ system
A group of different tissues working together to perform a specific function
E.g. Circulatory system
What is the order of the levels of organisation
Organelles -> Cells -> Tissue -> Organ -> Organ system
What is the order of the levels of organisation
Organelles -> Cells -> Tissue -> Organ -> Organ system
What is the function of the cell membrane
Controls movement of substances in and out of the cell
AC PC
What is the function of the cytoplasm
Majority of chemical reactions happen here
AC PC
What is the function of the nucleus
Contains genetic material and controls the activity of the cells
What is the function of ribosomes
Where proteins are made
AC PC
What is the function of mitochondria
Aerobic respiration is carried out here which gives the cell energy to work
AC PC
What is the function of the cell wall
Rigid structure made of cellulose that supports and strengthens cell
PC
What is the function of chloroplasts
Contain chlorophyll. Absorbs light for photosynthesis which makes food for the plant
PC
What is the function of the vacuole
Contains cell sap to support the cell
PC
