Answer:
The correct assertive is letter A.
Explanation:
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.
