Plant structure

Question 1

Function of ground tissue

Answer 1

Support/storage/transport

Question 2

Tissue that divides by mitosis + location

Answer 2

Meristematic in root tips

Question 3

Xylem have cells

Answer 3

dead at maturity

Question 4

Dicotyledonous

Answer 4

2 embryonic seed leaves

Question 5

Experiment to look at transverse section of dicot

Answer 5

busy lizzy
cut using a microtome and a scalpel
thin sections to allow light to pass through and therefore see the cells clearly
transferred to slide using paintbrush
fine focus

Question 6

How plants respond to high temperature

Answer 6

Transpiration/ production of heat absorbers to protect enzymes

Question 7

Function of waxy cuticle

Answer 7

prevent transpiration/ water loss

Question 8

Function of airspaces

Answer 8

greater surface area for gaseous exchange

Question 9

Function of stomata

Answer 9

Gaseous exchange

Question 10

Function of guard cells

Answer 10

Opening and closing of the stomata

Question 11

Function + location of dermal tissue

Answer 11

Protection/prevent water loss

upper or lower epidermis

Question 12

Monocot and dicot differences

Answer 12

Monocot contain one embryonic seed leaf - dicot have 2

Monocot have parallel veins - dicot have reticulate

Monocot have

Dicot flower parts are arranged in 4/5s

Question 13

Differences between xylem tracheids and vessels

Answer 13

Vessels have no end walls, tracheas have tapered ends

Tracheids are narrower + shorter in length

Question 14

function of xylem apart from transport

Answer 14

Support

Question 15

Role of companion cell and sieve plates

Answer 15

Contains nucleus/controls activities if sieve plates

Allow cytoplasm to move cell to cell
