The two main functions of roots are to deliver water and nutrients to the plant or tree and provide an anchor that keeps the plant or tree in the soil. Roots are generally the first part of any plant that emerges during germination.Know More
Roots should not be confused with stems, since roots grow down below the surface while stems grow up above the surface. Roots do not bear buds or leaves like stems do, although they do have fine hair-like structures that work to absorb minerals and water. Water passes up through the tiny root hairs and into the plant's vascular system. The process by which the water moves through the roots is called osmosis, and it can only occur when there is water inside the plant in a concentration that is higher than the surrounding soil or compost. If there's too much water in the soil, it has the opposite effect on a plant's roots in that it will cause water to be leached from the roots instead of taking water up into the root.
Notably, storage roots from certain plants like the carrot end up being eaten by humans. Other storage roots become tubers and rhizomes, like irises and dahlias.Learn More
Pea plants should be watered sparingly, but the soil should remain consistently moist without being saturated. The plant should be watered when the top inch of the soil is dry to the touch.Full Answer >
The main functions of the stem are to provide support for plant leaves, transport minerals and water from the soil and carry sugar or glucose made in the leaves to other plant parts. Plants can have herbaceous or woody stems.Full Answer >
If enough salt accumulates in the soil and into the root zone, it may dehydrate the plant and impede plant growth. Water with a high concentration of salt can prevent the roots from absorbing water from the surrounding soil and may cause stress to the plant.Full Answer >
The four main plant groups include Bryophyta and allies, Pteridophyta and allies, Coniferophyta and allies and Magnoliophyta. Plants from these groups all fall into one of three groups: nonvascular plants, vascular plants with spores and vascular plants with seeds.Full Answer >
