Structure of the leaf
At the top is cuticle
water protective layer covering the epidermal cells of leaves and other parts and limiting water loss.
Upper epidermis
. It helps protect the leaf by aiding in preventing water loss and providing an extra layer between the outside and inside of the leaf.
Palisade, mesophyll layer

Airspace, Stoma/Stomata and guard cells

function of the leaf
The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive

Chemosynthesis
-
Chemosynthesis is the process by which certain microbes create energy by mediating chemical reactions.
Fermentation = Glucose --> ethanol+carbon dioxide + (energy) = anaerobic respiration for plants = fermentation.
aerobic respiration
-
-
The more you exercise and it depends on the intensity, if the intensity is really high then you are going to need a lot more oxygen than you normally do so you at some point you are going to start respiring anaerobically, which keeps you going without oxygen
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy.
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise.
Key Ecosystem words
-
-
-
-
Niche = The role that an organism has within an ecosystem, For example, what it eats, where it lives
food chain
-
-
-
a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal.

Bioaccumulation
In every ecosystem, organisms are connected through food chains and food webs, if an organism has dangerous bacteria and it gets eaten, every animal that eats that organism gets the bacteria and the bacteria increases through each animal it passes through.
In every ecosystem, organisms are intricately interconnected through food chains and food webs. When toxins finds their way into an organism, they can build up and remain, this is called bioaccumulation
Ecosystems
All plants and algae that photosynthesises compete for light, water, minerals from the soil and space.
All animals compete for food, mates and territories. This is just like the Red squirrel vs the Grey squirrel. Even though the Grey Squirrel is superior
