Answers
Answer:
1) Root, in botany, that part of a vascular plant normally underground. ... Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
2) Stem. It functions as a skeleton by constituting a major part of the shoot system and firmly supports the other components like leaves, buds, flowers and fruits. The main stem originates through the direct prolongation of tigellum of the embryo and gives rise to the lateral stems, comprising leafy appendages, buds etc.
3)Taproot penetrates deep into the soil, while a fibrous root is shallow and does not penetrate as deeply. A taproot is the differentiated primary root of the plant, while the fibrous root is not the differentiated primary root of the plant. ... Taproot is found in dicots, while a fibrous root is found in monocots.
4) Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
Define root system. Give two functions of roots.
Roots are the important underground part of all vascular plants. This part of the plant is mainly responsible for anchoring it down into the ground and absorbing the essential mineral elements, nutrients, and water from the soil. It is also used to store food.
Roots perform various functions that are necessary for the survival of the plants. They are an integral or integrated system that helps the plant in:
Anchoring: Roots are the reason plants remain attached to the ground. They support the plant body, ensuring that it stands erect.
Absorption: Primary function of the roots is to absorb water and dissolved minerals from the soil. This is crucial as it helps in the process of photosynthesis.
Storage: Plants prepare food and store in the form of starch in the leaves, shoots and roots. Prominent examples include carrots, radish, beetroot, etc.
Reproduction: Even though roots are not the reproductive part of plants, they are vegetative parts. In some plants, the roots are a means of reproduction. For instance, new plants arise from creeping horizontal stems called runners (stolons) in jasmine, grass, etc. This type of reproduction is called vegetative propagation.
Ecological Function: They check soil erosion, provide sustenance and also habitat to various organisms.
Define shoot system. Give two functions of the stem.
The parts of a flowering plant that are visible above the ground such as the stems, leaves, buds, and flowers
Functions of stem
To provide support to the plant
Holding leaves, flowers, and buds.
How is a tap root different from a fibrous root? Give one example of each type.
Taproot penetrates deep into the soil, while a fibrous root is shallow and does not penetrate as deeply. A taproot is the differentiated primary root of the plant, while the fibrous root is not the differentiated primary root of the plant. Taproot is found in dicots, while a fibrous root is found in monocots.
Name the two parts of a stamen. State the functions of each of these two parts.
The two parts of stamen are Anther and Filament.
Function of anther is to produce male sex cells (pollen grains)
Function of filament is to supports the anther.
