Which chemical is most important in telling a plant when to flower?
phytochrome
nitrogen
carotenoid
chlorophyll
The chemical that is most important in telling a plant when to flower is phytochrome.
Which chemical is most important in telling a plant when to flower?Phytochrome is a blue-green pigment found in many plants, which regulates various developmental processes.Phytochrome is widely distributed in the plant kingdom. Although green leaves are the organs, which perceive daylight most effectively, their phytochrome content is very low. For this reason, most studies with phytochrome have used etiolated seedlings from which phytochrome has been obtained in highly purified form.The light receptors of plants are Phytochrome Red and Phytochrome Far Red. They are both color pigments found in leaves. They are chemically reactive and absorb red light at specific wavelengths. This chemical reaction tells the plant whether to continue vegetating or flowering.Hence, the phytochrome chemical is most important in telling a plant when to flower.

Visual summary for chapter 1 : what is Nutrition
What is Nutrition? Simply said, Nutrition is the study of food at work in our bodies, our source for energy, and the medium for which our nutrients can function. Think of nutrition as the building blocks of life.
The essential nutrients for life include carbohydrates, proteins, and lipids (fats), as well as fiber, vitamins, minerals, and water—the solvent for all soluble ingredients in the blood and cells. The absorption of nutrients starts the moment we begin to digest our foods, as they are transported to assist all the metabolic processes in the human body.
Good nutrition means getting the right amount of nutrients from healthy foods in the right combinations. Having nutrition knowledge and making smart choices about the foods you eat can and will help you achieve optimum health over your lifetime, and be a key to avoiding obesity, illness, and many of today’s most prevalent chronic diseases.
Nutrition is the study of the nutrients in food and how they affect our body's health. It involves understanding different types of nutrients, their functions, and concepts like energy balance and balanced diet.
Explanation:Nutrition is the study of the nutrients in food and how they affect our body's health. It explores the processes of digestion, absorption, and metabolism of nutrients, as well as the role of nutrients in growth, development, and disease prevention.

4.) Photosynthesis is often described as two series of reactions, the light dependent and the light-independent or Calvin cycle reactions. Describe all steps that occur in the light-dependent reactions, including raw materials, energy transfer, and products.
Answer:
photosynthesis is important in many helio-centered plants
Explanation:
The light-dependent reactions of photosynthesis convert sunlight into chemical energy within the thylakoid membranes, where water is split to oxygen, protons, and electrons, producing ATP and NADPH as energy carriers for the Calvin cycle.
Light-Dependent Reactions of Photosynthesis
These reactions take place within the thylakoid membranes of chloroplasts. When sunlight hits the chlorophyll and other pigments, it excites electrons that move through an electron transport chain. This process leads to the splitting of water molecules (H2O) into oxygen, protons, and electrons (photolysis). The protons contribute to a proton gradient that drives the synthesis of adenosine triphosphate (ATP) through chemiosmosis. Moreover, the excited electrons transfer from the water molecules to nicotine adenine dinucleotide phosphate (NADP+), forming NADPH. The crucial raw materials for these reactions are water and sunlight, resulting in the production of oxygen, ATP, and NADPH.
All these products are then used in the Calvin cycle, or the light-independent reactions, to convert carbon dioxide (CO2) into glucose, a process powered by the ATP and NADPH generated in the light-dependent reactions.

The chemical reactions that cells use to acquire and use energy to live, grow an reproduce are called
Metabolism refers to all of the chemical reactions occurring within cells that allow them to acquire and use energy, categorized into catabolic and anabolic pathways. Catabolic reactions break down complex molecules, releasing energy, while anabolic reactions build complex molecules and require energy.
Explanation:The chemical reactions that cells use to acquire and use energy to live, grow, and reproduce are collectively called metabolism. Metabolism encompasses all of the biochemical processes that take place within cells, which can be broadly categorized into two main types: catabolic and anabolic pathways. Catabolic pathways are the metabolic reactions that break down complex molecules into simpler ones, releasing energy in the process. On the other hand, anabolic pathways construct complex molecules from simpler ones and require an input of energy. These metabolic pathways are part of a larger field known as bioenergetics, which is concerned with the flow of energy through biological systems. Overall, metabolism maintains the cell's energy balance through the interplay of catabolic and anabolic reactions.
Final answer:
Cellular metabolism refers to all the chemical reactions in cells that are essential for acquiring and utilizing energy needed for survival, growth, and reproduction. It includes both energy-releasing catabolic reactions and energy-consuming anabolic reactions, all of which are regulated by enzymes within the realm of bioenergetics.
Explanation:
Cellular metabolism is the term used to describe the collection of chemical reactions that occur within cells to acquire and use energy necessary for the cells to live, grow, and reproduce. This encompasses a wide array of processes that include both catabolic reactions, which break down molecules to release energy, and anabolic reactions, which build up complex molecules requiring energy. Under the umbrella of bioenergetics, these reactions are crucial for energy flow through living systems and are regulated by enzymes to ensure the cell can function properly.
Understanding cellular metabolism is essential because it is the biochemical basis of life for all organisms. Whether a cell is taking in nutrients, synthesizing new components, or mobilizing energy reserves, it is the metabolic reactions that make these life-sustaining activities possible. Overall, cellular metabolism is a dynamic network of interconnected chemical reactions that are fundamental to biological systems.
