Flashcards do conjunto (13)
- 1What is a tissue?A group of cells that are specialised to work together to carry out a particular function. A tissue can contain more than one cell type
- 2Outline the structure of squamous epithelium tissueA single layer of flat cells lining a surface, a thin exchange surface for efficiency
E.g. alveoli - 3Outline the structure of ciliated epithelium tissueLayer of cells covered in cilia
Found on surfaces where things need to be moved (e.g. trachea)
The cilia wafts mucus along - 4Outline the structure of muscle tissueMade up of bundles of elongated cells (muscle fibres).
There are three types:
Smooth (e.g. lining the stomach)
Cardiac (in the heart)
Skeletal (used to move) - 5Outline the structure of cartilageA type of connective tissue found in the joints. Also shapes and supports ears, nose and trachea.
Formed when chondroblasts secrete an extracellular matrix (jelly- like substance containing protein fibres), which they become trapped inside - 6Outline the structure and function of xylem tissueSTRUCTURE:
Contains hollow xylem vessel cells (which are dead) and living parenchyma cells
FUNCTION:
Transports water around the plant and supports it - 7Outline the structure and function of phloem tissueSTRUCTURE:
Arranged in tubes and made up of sieve cells, companion cells and some ordinary plant cells.
Each sieve cell has end walls with holes in them, so that sap can move through them. These end walls are called sieve plates
FUNCTION:
Transport sugars around the plant - 8What are organs?A group of different tissues that work together to perform a particular function
- 9Outline the structure of lungsContain squamous epithelium tissue (alveoli) and ciliated epithelium tissue (bronchi etc.).
Also have elastic connective tissue and vascular tissue (blood vessels) - 10Outline the structure of the leafContains palisade tissue, epidermal tissue (prevent water loss), and xylem and phloem tissues in the veins
- 11What are organ systems?Organs work together to carry out a particular function
- 12Outline the structure of the respiratory systemLungs, trachea, larynx, nose, mouth and diaphragm
All organs, tissues and cells involved in gas exchange - 13Outline the structure of the circulatory systemHeart, arteries, veins and capillaries
Organs involved in blood supply
