Answers
Answer:
1) The vascular tissues of plants, which are composed of specialized conducting tissues, xylem and phloem, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.
2) The first root that comes from a plant is called the radicle. A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem.
3) There are two processes involved in how a plant absorbs water: capillary action and transpiration. ... The molecules in this tissue attract water molecules from the soil, so that the water is pulled upwards. This process is called capillary action.
4) When a new root hair cell grows, it excretes a poison so that the other cells in close proximity to it are unable to grow one of these hairs. This ensures equal and efficient distribution of the actual hairs on these cells.
5) Transpiration is important because a) It helps in absorption and upward movement of water and minerals from roots to leaves.
6)Micronutrients can be divided into four groups — water-soluble vitamins, fat-soluble vitamins, macrominerals and trace minerals.
Hope this may helpful my friend.
