Question 2

Name four types of tissues

Answer 2

1. nerve tissue e.g. nerve tissue in the brain made up of nerve cells called neurons
2. muscle tissues e.g. muscle tissues in the arm made up of muscle cells called fibres
3. connective tissue e.g. skin and blood made up of red and white blood cells
4. reproductive tissue e.g. in male tissue in the teste that produce sperm

Question 11

the structure of an organ is related to its ___

Answer 11

function

Question 12

name the hierarchical structure of organisation

Answer 12

cells make up tissue, tissue makes up organs, organs make up body systems and body systems make up multicellular organisms

Question 13

name the four types of plant tissue there are

Answer 13

epidermis tissue e.g. epidermis in which cells with a root hair are found near root tips

xylem tissue e.g. xylem inside the stem made up of tube-like cells called xylem vessels

mesophyll tissue e.g. mesophyll in leaves made up of palisade and spongy mesophyll cells

reproductive tissue e.g. in a flower cell in the ovary that produce ova
