An iceberg - it "lives" in water, melts in summer, and the visible portion of it grows as it melts, suggesting its roots are actually its base floating under the water.
A nitrogen fixing bacterium Rhizobium enters roots of pea plant and grows to form root nodules . Mycorrhizal fungi also grow on roots of pea palnt.
A tree grows down with its roots to anchor itself in the ground, while it grows up with its trunk and branches reaching towards the sky.
The part of the plant that grows upwards is primarily the stem, which supports the plant and elevates the leaves and flowers towards sunlight. This upward growth is driven by a process known as phototropism, where the plant bends or grows towards light sources. Additionally, the apical meristem, located at the tips of stems and roots, is responsible for producing new growth.
it grows short roots to adapt to the permafrost but that's all i know
The phenomenon where the roots of seedlings grow straight down and the stems grow straight up is explained by gravitropism. Roots exhibit positive gravitropism, responding to gravity by growing downward, while stems display negative gravitropism, growing upward against the pull of gravity. This adaptive behavior ensures that roots can access water and nutrients in the soil, while stems can reach sunlight for photosynthesis.
