Plants

Question 1

Is higher SA:Vol better

Answer 1

Yes, it maximizes efficiency. That’s why large organisms are multicellular

Question 2

What does ground tissue do

Answer 2

Forms the bulk of the plant body
Stores food and provides support

Question 3

Ground tissue in stem

Answer 3

Provides support and strength

Question 4

Ground tissue in roots

Answer 4

Store food and water

Question 5

Ground tissue in leaves

Answer 5

Location of photosynthesis

Question 6

Palisade tissue cells

Answer 6

Responsible for photosynthesis

Question 7

Spongy Mesophyll

Answer 7

Loosely packed for diffusion of gases

Question 8

Vascular tissue

Answer 8

Transports everything around the plant

Question 9

Xylem

Answer 9

Transports water

Question 10

Phloem

Answer 10

Transports sugar

Question 11

Shoot system

Answer 11

Everything above ground

Question 12

Root system

Answer 12

Everything below ground

Question 13

Meristems

Answer 13

The area of growth on the plant by the process of mitosis

Question 14

Stomata

Answer 14

Tiny pores in the ground tissue of leaves

Question 15

Guard cells

Answer 15

Specific cells that form stomata

Question 16

Gas exchange process

Answer 16

It occurs by diffusion across membranes. Stomata diffuse CO2 into palisade and spongy mesophyll diffuse O2 and H2O out of leaf. Stomata will open when there’s movement of water and Potassium

Question 17

Cellular respiration

Answer 17

Mitochondria use sugar to convert it into ATP. Carried out in plants and animals. Occurs day and night but most obvious at night when photosynthesis isn’t occurring

Question 18

What must be done for substances to be transported

Answer 18

All substances must be dissolved first in water

Question 19

Root hair function

Answer 19

Increases SA at roots for water intake

Question 20

What is transpiration

Answer 20

The exhalation of water vapour through the stomata

Question 21

Cohesion

Answer 21

Bond between water and water

Question 22

Adhesion

Answer 22

Bond between water and a surface

Question 23

What does adhesion and cohesion do

Answer 23

Draw water up xylem

Question 24

Phototropism

Answer 24

Plants need to carry out photosynthesis therefore grow toward light

Question 25

Difference between positive and negative phototropism

Answer 25

Positive phototropism grows towards light
Negative phototropism grows away from the light

Question 26

Gravitropism

Answer 26

Plants respond to the earths gravity

Question 27

Difference between positive and negative gravitropism

Answer 27

Positive grows towards(roots)
Negative grows away(stem)
