Why does bean seedling do not need a coleoptile?
Bean seedlings do not need a coleoptile because they are dicots, which means their seed structure and germination process differ from monocots like grasses. Instead of a coleoptile, bean seedlings have a seed coat that protects the embryonic plant as it emerges. The cotyledons, or seed leaves, of the bean provide the necessary nutrients to support initial growth above ground. This allows the seedling to develop without the protective sheath that monocots use for similar purposes.
Are cacti dicots?
Yes, cacti are dicots. Dicots are a type of flowering plant that have two seed leaves, whereas monocots have one seed leaf. Cacti belong to the class Magnoliopsida, which includes dicots.
IS A PECHAY SEED A DICOTS OR A MONOCOTS?
dicot
Why does the maize seedling have a coleoptile?
The coleoptile is a protective sheath that encases the emerging shoot of a maize seedling, guiding it as it grows upward through the soil. Its primary function is to shield the delicate shoot from mechanical damage and environmental stress while allowing it to penetrate the soil surface. The coleoptile also facilitates the seedling's efficient emergence by providing a streamlined structure that helps it break through the soil more easily.
Why peanuts are dicots?
no peanuts are not monocots. since they contain two cotyledons, they are dicots
What substance causes the coleoptile to bend?

What is the function of the coleoptile?
The coleoptile is a protective sheath that covers the emerging shoot of a germinating monocotyledonous seed, such as grasses. Its primary function is to shield the delicate shoot as it grows upward through the soil. Additionally, the coleoptile helps guide the shoot towards the light, ensuring proper orientation for photosynthesis and further growth. Once the shoot emerges, the coleoptile usually ceases to function, allowing the first true leaves to develop.
What color of light are effective in getting the coleoptile to bend?
i have the same ? but its blue

What is coleoptile role in germination?
The coleoptile is a sheath-like structure that covers and protects the emerging shoot of a germinating seed. It helps in pushing the shoot through the soil so that it can reach the surface and begin photosynthesizing. Additionally, the coleoptile helps in directing the growth of the shoot towards light.
How many species of dicots are there?
There are over 175,000 species of dicots, making it one of the largest groups of flowering plants. Dicots are characterized by having two seed leaves.
How many cotyledons do dicots have?
Dicots is short for dicotyledons. Di- is a prefix meaning two, dicotyledons (dicots) have two seed leaves, cotyledons.

What are the four main differences between monocots and dicots?
1. Monocots have one cotyledon in the embryo and dicots have two 2. Vascular bundles in monocots are closed in dicots these are open 3. Leaves have parallel venation in monocots & reticulate in dicots 4. Floral parts are in multiple of three in monocots, and five or their multiple in dicots.
