CELLULAR RESPIRATION

Respiration and Excretion in plants

C6H12O6  +  6O                            6CO +  6H2O  + Energy

Glucose     Oxygen            Carbon iv oxide Water

The equation represents only a summary of the raw materials and the end products of tissue respiration. The complex pathway of cellular respiration is shown below:

 

TYPES OF RESPIRATION

You already know that we have external and internal respiration, while external deals with breathing in and out i.e. inhalation and exhalation, the internal which takes place in the cell hence, cellular respiration is divided into two basic parts:

  1. Anaerobic Respiration and
  2. Aerobic Respiration

Anaerobic respiration is that type which involve the use of very little or no Oxygen, while Aerobic Respiration is that type which involves the use of large amount of Oxygen.

 

  1. Anaerobic respiration

Converting Food to Usable Energy

 

       2. AEROBIC RESPIRATION

C6H12O6  +  6O2                              6CO +  6H2O  + Energy

Glucose     Oxygen            Carbon iv oxide Water

 

 

EXCRETION

 

Excretory System of some organisms

ORGANISM EXCRETORY SYSTEM
Some unicellular organism Contractile Vacuole
Flatworms Flame cells
Annelids (e.g. earthworm) Nephridia
Insects Malpighian tubules
Vertebrates Kidneys, lungs, skin, and liver.
Plants Stomata and Linticels

 

EXCRETORY ORGANS AND SUBSTANCES THEY EXCRETE IN VERTEBRATES

IN ANIMAL

  1. Lungs: Carbon (iv) oxide, and water vapour.
  2. Skin: Sweats, Salts, and nitrogenous waste.
  3. Kidney: Urea, excess water, excess salts, ammonium compounds, and acids.
  4. Liver: Bile Pigments.

IN PLANTS

  1. Stomata: Oxygen, Carbon (iv) oxide, and water vapor.
  2. Bark: Tannins, resins, and latex.
  3. Leaves: Crystals of calcium oxalate, calcium carbonate, and anthocyanin pigments which give red, blue, and violet colors to many flowers.
  4. Lenticels: Oxygen, Carbon (IV) oxide, and vapor.
