WEBA whole baby plant is nestled inside that tiny, growing bean seed. A bean needs water to grow. At first, it absorbs this through a small hole called the micropyle that is found in the hilum , the scar on the side of the bean that shows where it was attached to its parent plant.
Hilum (biology) - Wikipedia
WEBIn botany, a hilum (pronounced / ˈhaɪləm /) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). On a bean seed, the hilum is called the "eye".
Seed Scarification Techniques - How To Nick Flower Seeds Before ...
WEBAug 26, 2022 · Seeds with an impermeable (waterproof) seed coat can benefit the most from nicking. Large or hard seeds like those of beans, okra, and nasturtium often require scarification for optimal germination. Most plants in the tomato and morning glory families also have impermeable seed coats and will germinate better after scarification.

WEBThe hilum is a scar on the outside of the seed where it was attached to the endocarp (inner layer of the fruit wall). The micropyle is a small round structure next to the hilum where the pollen tube entered.
Seed Scarification: How to Scarify Seeds For Better Germination
WEBApr 1, 2024 · Mechanical abrasion is likely the most popular method to scarify seeds for the home gardener, is the least risky, and is quite simple. It works well for species considered “hard seeds,” which are known to have a water-impermeable outer shell or coating, like lima beans, chickpeas, nasturtium, and …
WEBOn the pinto bean, a distinctive oval light area on the seed coat will be observed. This is the hilum and is the scar where the developing seed was attached through the funiculus (like an umbilical
Anatomy of a Bean Seed: A Visual Guide - Data Visual Expert
WEBIn this article, we will explore the different parts of a bean seed, their functions, and their importance in the growth process. The outermost layer of a bean seed is called the seed coat. This protective layer acts as a barrier, shielding the delicate embryo within from damage and dehydration.
WEBObtain 2 or 3 soaked bean seeds. Observe the scar on the seed coat, the hilum, where the seed was attached to the wall of the pod. Beside the hilum there is a small opening, the micropyle, through which the pollen tube enters the ovule. Remove the seed coat (testa) and notice the two cotyledons. The embryonic axis lies between the two cotyledons.
WEBGermination process of seed can be observed with various methods of seed scarification. Scarification is a pretreatment of seeds that aims to break seed dormancy and accelerate the occurrence of uniform seed germination.

WEBCorrected statement — Testa is the outermost layer of the seed. Fill in the blanks by choosing the correct alternative. Answer. In a dry seed, the embryo is in quiescent state. Water is absorbed by the seed mainly through micropyle. Very low temperature inhibits the growth of embryo. Germination in Pea is hypogeal.
