They conduct only respiration. Animals are not photosynthetic.
The skin takes part in excretion through the release of sweat, which helps eliminate waste products such as urea, salts, and water from the body. Sweat glands in the skin excrete these waste products through the process of perspiration.
In aerobic respiration 38 ATPs are produced. In anerobic respiration only 2 are produced
Respiration is basically what keeps living things alive. There are 2 forms of respiration aerobic (oxygen based) and anaerobic (non-oxygen based). Aerobic respiration is more efficient, but anaerobic respiration evolved first because when life first appeared earth had no oxygen. The purpose of respiration is to extract energy from the simple sugars and fats extracted from food when it is digested.
Diffusion occurs across simple epithelial tissue. These are only one layer.
osmosses is diffusion of water only
Many small or simple creatures have no heart. If you are made of only one or a very few cells you have no need of a circulation system because substances can travel sufficiently fast by diffusion. A jellyfish is an example.
active transport and osmosis
Osmosis only works BECAUSE OF diffusion.
Um, Well it's Mrs Gren and it stands for M = Movement R = Respiration S = Sensitivity G = Growth R = Reproduction E = Excretion N = Nutrition
diffusion is when the materials go through the cell membrane between the capillaries (because capillaries are only one cell thick)

If there is two, I could only guess urination and sweating.

Osmosis is the special form of diffusion that applies only to water. It is the movement of water molecules from an area of high concentration to an area of low concentration across a semipermeable membrane.

It is similar with defecation only in that both help to overcome nitrogenous wastes in the body. Defecation helps to pass out the solid wastes. But defecation can not be called excretion on the physiological grounds as the waste does not cross any semipermeable membrane as is required in the process of excretion.
