L- 1.Nutrition In Plants
Stomata
Tiny pores
Present on the surface of the leaf
Surrounded by Guard Cells
Responsible for the exchange of gases
Vessels
Transports water and minerals
Run throughout the root,stem,branches and leaves
Form a continuous path or passage for the nutrients to reach the leaf
Chlorophyll
Helps leaves capture sunlight
Solar energy from the sun in is used to synthesis food
Using carbon dioxide and water
Green pigment
Reason for the colour of the leaves to be Green
Leaves other than green colour
Contain chlorophyll
large amount of red and brown and other pigments mask the green colour
Algae contain chlorophyll
Photosynthesis
Solar Energy is stored in the plant in the form of food
Thus sun is the ultimate source of food and energy
Also termed as
Glucose
Carbohydrates
Starch
Photo - Light
Synthesis - To combine
Carbon dioxide + water ---->Carbohydrate + Oxygen
Products of photosynthesis : Starch/Glucose/Carbohydrate and Oxygen
This is the reason that Photosynthesis is important
The oxygen released is essential for animal life to breathe
Carbohydrate are essential for herbivorous animals to eat.
Synthesis of plant food other than Carbohydrates
Proteins
Nitrogenous
Contain Nitrogen
Get their nutrients by this process
Or also the farmers add fertilizers to the soil rich in nitrogen
Plants cannot absorb Nitrogen present in the air directly from stomata
Soil contain Bacteria
Rhizobium
Converts gaseous Nitrogen to a soluble form
Plants can then Absorb the soluble nitrogen
