Q. Which process causes this change?
Excretion, irritability and reproduction are characteristics of:
Plants and animals have all the following characteristics: excretion, irritability and reproduction. Let's talk firstly about the plants.
Plants can excrete through stomatal pores in the leaves. The main metabolic reactions that occur in a plant that produces these residues are cellular respiration and photosynthesis. However, this place isn't the only that works as a way of excretion. Plants also excrete solid or slimy things. Talking about irritability, plants can have a reaction about all kind of stimulus, as chemical as phisical. For instance, the lights, the weather, animals around it, temperature and chemical changes inside the plants. About reproduction, plants can reproduce inside the gyno, the female sexual organ of plants. The gynoecium consists of the ovary, which produces and stores the eggs. In the eggs there are also the sex cells of the plant. Now talking about the animals, they have all sort of process, but is more complex than plants. You have about nine phylus in Animal Kingdom, and all sort of phylus has your unique excretion, irritability and reproduction.
