tiny gaps in the epidermis of the leaf

Tiny air sacs that have thin membranes so gases can diffuse, Tiny air sacs which oxygen and carbon dioxide move through, Tiny air sacs with many folds to increase the surface area

Biology: Transport in animals and plants Flashcards

1

Water moves from the xylem to the plant cells by...

none of them
Osmosis
Diffusion
Active transport

2

What do fish have to make diffusion efficient?

Mouths
Gill filaments
Lamellae
Gills

3

Transpiration is when...

You sweat during exercise
water moves from high water potential to low water potential
water is lost through the stomata
Sugars are moved through the plant

4

The stomata are...

waxy layer on top of the leaf
tiny gaps in the epidermis of the leaf
cells that guard the gaps
the stem of the plant

5

The function of the xylem is...

To transport water
To transport sugars and minerals
To transport sugars
To transport water and minerals

6

The function of the phloem is....

To transport water and minerals
To transport sugars and minerals
To transport sugars
To transport water

7

Isotonic means...

none of them
Lower concentration
Higher concentration
Same concentration

8

Villi are folds in the small intestine which increase the surface area so...

less water can diffuse into the bloodstream
less glucose can diffuse into the bloodstream
more glucose can diffuse into the bloodstream
More water can diffuse into the bloodstream

9

In biology folds are important because...

they shorten the diffusion distance
They increase the surface area
we have too much to fit in
not quite sure

10

Alveoli are...

Tiny air sacs that have thin membranes so gases can diffuse
Tiny air sacs which oxygen and carbon dioxide move through
Tiny air sacs with many folds to increase the surface area
A structure in a plant
