Part 1- The length and width of this piece of leaf surface are both 0.1mm.

Calculate the number of stomata per mm^2 of this leaf surface.


Part 2- a different plant species has 400 stomata per mm^2 of leg surface.

Having a large number of stomata per mm^2 of leaf surface can be a disadvantage to a plant.

Give one disadvantage.

Answer:

I) 200 per mm^2

ii) there will be more water loss via transpiration

Explanation:

I) as you can see there are 2 stomata

calculate the area of the surface:

0.1 × 0.1 = 0.01mm^2

2 ÷ 0.01 = 200

Part 1: The number of stomata per mm^2 is 200 mm^2

Part 2: The disadvantage of this seemingly large surface area is that the leaf tends to loss more water by transpiration

Part 1:

How to calculate the stomatal number

First, find the area

Area = length * width

Area = 0. 1* 0. 1 = 0.01 mm^2

Stomatal number of a leaf is the average number of stomata per square millimeters of epidermis of the leaf.

Number of stomata per mm^2 = number of stomata / area in mm^2

Note that the number of stomata from the diagram is 2

Number of stomata per mm^2 = 2/0. 01 = 200 mm^2

Part 2:

In a different species with 400 stomata per mm^2 of leaf surface, there would, the disadvantage of this seemingly large surface area is that the leaf tends to loss more water by transpiration
