Veronicastrum virginicum, or Culver's root, is a species of flowering plant in the plantain family, Plantaginaceae. It is native to the eastern United States and south-eastern Canada. Growing to 200 cm (79 in) tall by 45 cm (18 in) broad, it is an erect herbaceous perennial with slender racemes of white or occasionally pink or purple flowers in ...
The apical meristems start growing and give rise to the root and shoot. The first "true" leaves expand and can often be distinguished from the round cotyledons through their species-dependent distinct shapes. [1] While the plant is growing and developing additional leaves, the cotyledons eventually senesce and fall off.
The stages of germination of a pea plant: A. seed coat, B. radicle, C. primary root, D. secondary root, E. cotyledon, F. plumule, G. leaf, H. tap root. The part of the plant that first emerges from the seed is the embryonic root, termed the radicle or primary root. It allows the seedling to become anchored in the ground and start absorbing water.
Podophyllum peltatum is an herbaceous perennial plant in the family Berberidaceae. Its common names are mayapple, American mandrake, wild mandrake, [4] and ground lemon. [5] It is widespread across most of the eastern United States and southeastern Canada. [6] [7] Mayapples are woodland plants, typically growing in colonies derived
On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
The correct environment of air, mineral nutrients and water directs plant roots to grow in any direction to meet the plant's needs. Roots will shy or shrink away from dry [22] or other poor soil conditions. Gravitropism directs roots to grow downward at germination, the growth mechanism of plants that also causes the shoot to grow upward. [23]

Basal shoots, root sprouts, adventitious shoots, and suckers are words for various kinds of shoots that grow from adventitious buds on the base of a tree or shrub, or from adventitious buds on its roots. Shoots that grow from buds on the base of a tree or shrub are called basal shoots; these are distinguished from shoots that grow from ...
