Answer:
When the seed germinates, the two cotyledons emerge from the soil to form the seed leaves. The seed leaves nourish the plant until it can form its true leaves. (Not all dicots' seed leaves emerge during germination; for example, peas are dicots, but the pea cotyledons remain underground.)

Answer and Explanation:
a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.
b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.
c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.
Answer:
Biology, study of living things and their vital processes. The field deals with all the physicochemical aspects of life. ... Modern principles of other fields—chemistry, medicine, and physics, for example—are integrated with those of biology in areas such as biochemistry, biomedicine, and biophysics.
