Answers
Answer:
1) The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
2) parallel venation
Plants with fibrous roots have parallel venation in their leaves. For example, grass, wheat maize, etc., have fibrous roots with parallel venation.
3) taproot
If the leaf has parallel venation, it is likely to have fibrous root, but if the leaf has reticulate venation, the plant will have a taproot.
4) typical flower has four main parts—or whorls—known as the calyx, corolla, androecium, and gynoecium (Figure 1). The outermost whorl of the flower has green, leafy structures known as sepals. The sepals, collectively called the calyx, help to protect the unopened bud.
5) It supports the petals. Complete Answer: - Flowers with joined sepals are Hibiscus which is also known as china rose and another one is periwinkle. - Flowers with separated sepals are Magnolia and Rose
