Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.
Which vessel in the plant is responsible for transporting sugars *?
Which cell is responsible for transportation of food?
What are the materials transported in plants?
Which vessel in the plant is responsible for transporting sugars and amino acids?
How does a plant increase in biomass?
Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes.
How does food manufactured in photosynthesis reach storage areas in the root?
These sugars are transported across the plant by the phloem a mechanism known as translocation. Sinks are sugar distribution points such as roots young shoots and developing plants. The product of photosynthesis is transported from source of production to the storage organs through Phloem.
Is blood a tissue?
Blood is one of the connective tissues. As a connective tissue, it consists of cells and cell fragments (formed elements) suspended in an intercellular matrix (plasma). Blood is the only liquid tissue in the body that measures about 5 liters in the adult human and accounts for 8 percent of the body weight.
How water and minerals are transported in plants?
Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants- xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
How would you test the presence of starch in leaves?
- The presence of starch in leaves can be tested by the Iodine test.
- When we remove chlorophyll from the leaf by boiling it in alcohol and then putting two drops of iodine solution, it is a colour change to blue indicates the presence of starch.

How does water flow up a plant?
Plant stems have some very special cells called xylem. These cells form long thin tubes that run from the roots up the stems to the leaves. Their job is to carry water upward from the roots to every part of a plant.
How water is transported from soil to the leaves of plants Class 7?
Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants- xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
What causes unloading of sucrose at sink cell?
Sucrose concentration in the sink cells is lower than in the phloem STEs, so unloading at the sink end of the phloem tube occurs by either diffusion or active transport of sucrose molecules from an area of high concentration to one of low concentration.
What is biomass in a food chain?
Biomass is the energy in living organisms. Autotrophs, the producers in a food web, convert the sun’s energy into biomass. Biomass decreases with each trophic level. There is always more biomass in lower trophic levels than in higher ones.
What type of fire system is used in bio power?
What type of fire system is used in Bio power? Explanation: Most of the bio power plants are direct fired systems. They burn bio energy feed stocks directly to produce steam. This steam drives a turbine, which in turns a generator that converts the power into electricity.
What role does water potential play in the transport of sugar in a plant?
This movement of water into the sieve tube cells cause Ψp to increase, increasing both the turgor pressure in the phloem and the total water potential in the phloem at the source. This increase in water potential drives the bulk flow of phloem from source to sink.
What is the direction of flow of water in xylem and food in phloem?
The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.
What color is your blood inside your body?
Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue.
What percent of blood is water?
Over 90% of blood plasma is water, while less than 10% consists of dissolved substances, mostly proteins. Blood plasma also contains electrolytes, vitamins and nutrients such as glucose and amino acids. Over 99% of the solid particles in blood are cells known as red blood cells (erythrocytes) due to their red color.
What are the raw materials required by green plants to prepare their own food?
Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials. Chlorophyll is a substance in all green plants, especially in the leaves.
What are the methods used by plants to get rid of excretory products Brainly?
Transpiration is the exhalation of water vapor via the stomata. The gaseous wastes like carbon dioxide during night are removed through the stomata present on the surfaces of the leaves. Some of the excretory wastes gather in the vacuoles of the cell, which ultimately turn into gum and resin.
