Is root cap absent in xerophytes?
No, root caps are not absent in xerophytes. They are present in xerophytes just like in other plant species. Root caps are important for protecting the root apical meristem as the root grows through the soil, regardless of the plant's environment.
Are Centrioles absent from higher plants and fungi?
Yes, centrioles are generally absent in higher plants such as angiosperms and gymnosperms. However, some lower plant species like mosses may possess structures that function similarly to centrioles. In fungi, centrioles are generally absent, and instead, microtubule organizing centers help with cell division.
Why do the roots of some aquatic plants become reduced or at times absent?
Root pressure is osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or whentranspiration is low during the day. When transpiration is high, xylem sap is usually under tension, rather than under pressure, due to transpirational pull. At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves. Root pressure is studied by removing the shoot of a plant near the soil level. Xylem sap will exude from the cut stemfor hours or days due to root pressure. If a pressure gauge is attached to the cut stem, the root pressure can be measured.Root pressure is caused by active distribution of mineral nutrient ions into the root xylem. Without transpiration to carry the ions up the stem, they accumulate in the root xylem and lower the water potential. Water then diffuses from the soil into the root xylem due toosmosis. Root pressure is caused by this accumulation of water in the xylem pushing on the rigid cells. Root pressure provides a force, which pushes water up the stem, but it is not enough to account for the movement of water to leaves at the top of the tallesttrees. The maximum root pressure measured in some plants can raise water only to about 7 meters, and the tallest trees are over 100 meters tall.
Is root cap absent in epiphytes?
Yes, root caps are generally absent in epiphytes. Epiphytes, which grow on other plants for support, often have specialized root structures that do not require a root cap, as they absorb moisture and nutrients from the air and surrounding environment rather than from the soil. Their roots are typically adapted for anchoring to their host plants rather than penetrating the ground.
What pressure is help water from soil enters into the root hairs owing to?
The pressure that helps water from the soil enter root hairs is called root pressure. This pressure is generated by the active transport of ions into the root cells, creating a concentration gradient that drives water movement by osmosis. Root pressure is more significant in young, actively growing plants.
Is root cap absent in xerophytes?
No, root caps are not absent in xerophytes. They are present in xerophytes just like in other plant species. Root caps are important for protecting the root apical meristem as the root grows through the soil, regardless of the plant's environment.
What are the characteristic of gymnosperms?
Every gymnosperm produces naked seeds. In addition, many gymnosperms have needle-like or scale-like leaves, and deep-growing root systems.
What is the meaning of the root words in absentee?
The root word "absent" means not present or missing. When combined with the suffix "-ee," it denotes someone who is absent or missing, as in an "absentee" voter or landlord.
Which of the following would be associated with vascular plants A root systems B bryophytes C angiosperms D gymnosperms E shoot systems?
A) Root systems, C) Angiosperms, and D) Gymnosperms are all associated with vascular plants. Bryophytes are non-vascular plants and do not have true roots or vascular tissues. Shoot systems are present in both vascular and non-vascular plants.
Are Centrioles absent from higher plants and fungi?
Yes, centrioles are generally absent in higher plants such as angiosperms and gymnosperms. However, some lower plant species like mosses may possess structures that function similarly to centrioles.
