Endospermic seeds are found inA. barleyB. castorC. peaD. both (a) and (b) |
|
Answer» Correct Answer - D Food storing tissue of a seed is endosperm. In flowering plants. It is produced as a result of double fertillsation. In most monocot and some dicot seeds, the food reserve remains in the endosperm. They are called endospermic or albuminous seeds, e.g., cereals, castor bean, cocount, rubber. In majority of dicot seeds (e.g, pea gram, bean, mustard,groundnut) and some monocot seeds (e.g., orchids, Sagittaria), the endosperm is consumed during seed development and the food is stored in cotyledons and other regions. they are called non-endospermic or exalbuminous seeds. |

MODIFICATIONS OF STEM |
|
Answer» Stems of various plants have undergone modifications to perform different functions. Underground stems or storage stems: Examples: Rhizomes, Corms, tubers In ginger and banana, the underground stem is called a rhizome. The underground stem in Colocasia (arvi) is known as corm. Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it. Subtended by a leaf scar, these eyes bear buds that give rise to new plants. Supportive stems Example: tendril The stem in some weak plants bear thin, slender, and spirally-coiled structures called tendrils that help the plant get attached to nearby structures for support. Tendrils are found in cucumbers, melons, and other members of the family Cucurbitaceae. Protective stems Example: Thorns The stem in bougainvillea and citrus plants (like lemon and orange) bear sharp, pointed structures called thorns, which provide protection to the plant from herbivores. Photosynthetic stems Example: Opuntia The stem in the Opuntia is green. It carries out the process of photosynthesis in the absence of leaves. Others stem modifications In some plants, underground stems such as grasses spread in the soil and help in perenation. These stems are called runners. The short lateral stem called the offset in some aquatic plants (such as Eichhornia) bears leaves and tufts of roots at the node and gives rise to new plants. |

How do the various leaf modifications help plants? |
|
Answer» The main function of the leaves is to carry out the process of photosynthesis. However, in a few plants, leaves are modified to perform different functions. (a) Tendrils: The leaves of a pea plant are modified into tendrils that help the plant in climbing. (b) Spines: The leaves in cactus are modified into sharp spines that act as an organ of defence. (c) Phyllode: The leaves of some Australian acacia are short-lived and soon replaced by flattened, green structures called phyllodes that arise from the petiole of the leaves. The petioles in these plants synthesize food. (d) Pitcher: The leaves of the pitcher plant are modified into pitcher-like structures, which contain digestive juices and help in trapping and digesting insects. |
