Photosynthesis, as we noted earlier, is the biological conversion of light or electromagnetic energy from the Sun into chemical energy. It occurs in green plants, alga, and some types of bacteria and requires a series of biochemical reactions. Higher plants have structures called chloroplasts, which contain a dark green or blue-black chemical known as chlorophyll. Light absorption by chlorophyll catalyze, or speeds up, the process of photosynthesis. (A catalystis a substance that accelerates a chemical reaction without participating in it.)
In photosynthesis, carbon dioxideand water react with each other in the presence of light and chlorophyll to produce a simple carbohydrate and oxygen. This is one of those statements in the realm of science that at first glance sounds a bit dry and boring but which, in fact, encompasses one of life's great mysteries-a concept far more captivating than any number of imaginary, fantastic, or pseudoscientific ideas one could concoct. Photosynthesis is one of the most essential life-sustaining processes, making possible the nutrition of all things and the respirationof animals and other oxygen-breathing organisms.
In photosynthesis, plants take a waste product of human and animal respiration and, through a series of chemical reactions, produce both food and oxygen. The food gives nourishmentto the plant, which, unlike an animal, is capable of producing its own nutrition from its own body with the aid only of sunlight and a few chemical compounds. Later, when the plant is eaten by an animal or when it dies and is consumed by bacteria and other decomposers, it will pass on its carbohydrate content to other creatures. (See Food Webs for more about plants as autotrophs and the relationships among primary producers, consumers, and decomposers.)
A carbohydrate is not the only useful product of the photosynthetic reaction. The reaction produces an extremely important waste by-product-waste, that is, from the viewpoint of the plant, which has no need of oxygen. Yet the oxygen it generates in photosynthesis makes life possible for animals and many single-cell life-forms, which depend on oxygen for respiration.
What else can I help you with?
What describe the role of phloem in a vascular plant?
Phloem is a conductive plant tissue and is found in the stems and leaf veins. It facilitates the movement of the sugars produced by photosynthesis to the rest of the plant. Phloem also provides a minor role in the support structure of the stem.
Does the roots of a plant carry water and food to the rest of the plant?
Yes, the roots of a plant absorb water and minerals from the soil and transport them to the rest of the plant through the stem and leaves. The roots also play a role in storing and transporting nutrients and sugars produced during photosynthesis.
What are the plant tissues that conduct water and food?
Xylem tissue conducts water and minerals from the roots to the rest of the plant, while phloem tissue conducts sugars and other organic compounds produced during photosynthesis from the leaves to other parts of the plant.
What is the main transportation system of a plant?
The main transportation system of a plant is its vascular system, which includes xylem and phloem. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars produced during photosynthesis to various parts of the plant for energy or storage.
Why is it important that tubes connect the leaf with the plant?
Tubes, or vascular tissue, connect the leaf with the rest of the plant to transport water, nutrients, and sugars. This connection is vital for leaf function, as water and nutrients from the roots are taken up and transported to the leaf for photosynthesis. Additionally, the sugars produced during photosynthesis are transported out of the leaf to other parts of the plant for growth and energy storage. Therefore, the presence of tubes ensures the proper functioning and survival of the leaf and overall plant.
What describe the role of phloem in a vascular plant?
Phloem is a conductive plant tissue and is found in the stems and leaf veins. It facilitates the movement of the sugars produced by photosynthesis to the rest of the plant. Phloem also provides a minor role in the support structure of the stem.
How does sugar made in photosynthesis get to the rest of the plant?
Via the phloem, which transfer sugars Produced during photosynthesis from the leaves to all over the plant.
Does the roots of a plant carry water and food to the rest of the plant?
Yes, the roots of a plant absorb water and minerals from the soil and transport them to the rest of the plant through the stem and leaves. The roots also play a role in storing and transporting nutrients and sugars produced during photosynthesis.
Where water goes in a plant?
most of it (98%) will go through the plant the rest will be used in photosynthesis
How are nutrients transported to the cells in a plant?
Nutrients are transported to the cells in a plant through the xylem and phloem. The xylem carries water and minerals from the roots to the rest of the plant, while the phloem transports sugars and organic compounds produced during photosynthesis to different parts of the plant.
What are the plant tissues that conduct water and food?
Xylem tissue conducts water and minerals from the roots to the rest of the plant, while phloem tissue conducts sugars and other organic compounds produced during photosynthesis from the leaves to other parts of the plant.
What is the main transportation system of a plant?
The main transportation system of a plant is its vascular system, which includes xylem and phloem. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars produced during photosynthesis to various parts of the plant for energy or storage.
What are the products of photosynthesis Where do they go?
The products of photosynthesis are glucose (sugar) and oxygen. Glucose is used as an energy source by the plant for growth, reproduction, and maintenance. Some of the oxygen produced is used by the plant for respiration, while the rest is released into the atmosphere as a byproduct.
What is the purpose of the vascular system in plant?
The vascular system in plants facilitates the transport of nutrients, water, and hormones throughout the plant. It consists of xylem, which carries water and minerals from the roots to the rest of the plant, and phloem, which transports sugars produced during photosynthesis to different parts of the plant.
What raw materials do the veins in a leaf carry?
Veins in a leaf carry water, nutrients, and sugars throughout the plant. Water and minerals are absorbed by the roots from the soil and transported through the veins to the rest of the plant for photosynthesis and growth. Sugars produced during photosynthesis are also transported through the veins to provide energy for various plant functions.
What are The types of vascular tissue inside plants that transport energy from photosynthesis and materials from the roots to the rest of the plant are called?
The types of vascular tissue inside plants that transport materials are xylem (transports water and minerals from roots to leaves) and phloem (transports sugars and other nutrients produced in photosynthesis to various parts of the plant).
What is carried in the xylem and phloem?
The xylem carries water and minerals from the roots to the rest of the plant, while the phloem carries sugars and other organic compounds produced during photosynthesis from the leaves to other parts of the plant for growth and energy.
