Answers

Plumule
Definition
It is the embryonic root of the plant. It is the embryonic shoot of the plant.
Direction of Growing
It grows downwards into the soil. It grows upwards into the air.
Colour
It is whitish in colour. It is less whitish in colour.
Consequence
It is the first part of the seedling. It grows after the radicle.
Development
It develops into the root. It develops into the shoot.
Phototrophic
It is negatively phototrophic. It is positively phototrophic.
Geotropic
It is positively geotropic. It is negatively geotropic.
Hypertrophic
It is positively hydrotropic. It is negatively hydrotropic.
Function
It absorbs water and minerals from the soil. It produces food by the process of photosynthesis.
Explanation:
The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling. In gymnosperms and dicotyledons (angiosperms with two seed leaves), the radicle becomes a taproot whereas The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumuledoes not occur until the cotyledons have grown above ground.
