What is a tissue?

Group of cells specialised to work together to carry out a particular function

2

(Animal tissue) What is squamous epithelium?

Single layer of flat cells

3

(Animal tissue) where is squamous epithelium found?

Alveoli in the lungs

4

(Animal tissue) what is ciliated epithelium?

Layer of cells covered in cilia

5

(Animal tissue) where is it found?

The trachea where cilia wafts mucous

6

(Animal tissue) what is muscle tissue made up of?

Bundles of muscle fibres

7

(Animal tissue) what are the 3 types of muscle tissue and where are they found?

Cardiac - heart
Skeletal
Smooth - stomach wall

8

(Animal tissue) what is cartilage and where is it generally found?

Connective tissue
Found at the joints

9

(Animal tissue) what does cartilage shape and support?

The nose and windpipe

10

(Animal tissue) cartilage is formed when cells called chondroblasts do what?

Secrete an extra cellular matrix ( jelly like containing protein fibres) which they become trapped in side

11

(Plant tissue) why is the role of xylem tissue?

Transport water
Support the plant

12

(Plant tissue) what does xylem contain?

Dead hollow xylem vessels
Living parenchyma

13

(Plant tissue) what is the function of phloem tissue?

Transport sugars around the plant

14

(Plant tissue) phloem tissue is arranged in what?

Tubes

15

(Plant tissue) phloem tissue is made up of what?

Sieve tube elements
Companion cell
Some ordinary plant cells

16

(Plant tissue) each sieve cell and end walls with holes in them for what purpose? And what is their name?

So sap can move easily through
Sieve plates

17

What is an organ?

Group of different tissues working together to perform a particular function

18

(Organs) what tissues work together in the lungs?

Squamous epithelium in the alveoli
Ciliates epithelium in the bronchi
Elastic connective tissue and vascular tissue in the blood vessels

19

(Organs) what tissues in leaves work together?

Palisade cells for photosynthesis
Epidermal tissue to prevent water loss
Xylem and phloem

20

What is an organ system?

group of organs working together to perform a particular function

Lungs
Trachea
Larynx
Nose
Mouth
Diaphragm
All involved in breathing

(Organ systems) what is the circulatory system made up of?

Organs involved in blood supply
Heart
Arteries
Veins
Capillaries
