The understory is the underlying layer of vegetation in a forest or wooded area, especially the trees and shrubs growing between the forest canopy and the forest floor. Plants in the understory comprise an assortment of seedlings and saplings of canopy trees together with specialist understory shrubs and herbs.
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

Many houseplants are either epiphytes or live in seasonally dry ecosystems that help them adapt to the dry indoor air and inconsistent watering many houseplants are subject to. Often, houseplants from tropical areas are understory plants, and because they grown in shady conditions naturally, they are often able to thrive in lower-light conditions.
Dead, dry leaves make the twigs less nutritious and less palatable. [17] They are also more noisy when browsed, thereby potentially deterring browsers. [18] Species that display marcescence, such as beech and oak, have adapted to retaining their leaves for prolonged periods to thrive in difficult growing media.
With Black Oaks being forced to compete with conifer trees they are forced to grow taller and narrower when in the past they would have low branches extending for 30–40 ft. On these low branches children would run and play while their family could easily gather everything they needed. [6]
Dry, one-seeded indehiscent fruit [11] in which the true fruit is not the so-called "berry", but the achenes, which are the so-called "seeds" on the infructescence, e.g. in the genus Fragaria. acicular Slender or needle-shaped. [11] See also Leaf shape. acropetal Moving from roots to leaves, e.g. of molecular signals in plants. acrophyll
Due to their vertical structure, trees are more susceptible to cold than more ground-hugging forms of plants. [6] Summer warmth generally sets the limit to which tree growth can occur: while tree line conifers are very frost-hardy during most of the year, they become sensitive to just 1 or 2 degrees of frost in mid-summer.
Quercus coccinea is a medium to large deciduous tree growing to around 5.5–7.3 metres (18–24 feet) with an open, rounded crown; the maximum height is approximately 30 m (100 ft).
