What are functional traits in plants?
Plant functional traits are defined as any morpho-, physio-, and phenological plant characteristics affecting overall plant fitness through their influence on survival, growth, and reproduction (Violle et al., 2007).
What is leaf functional traits?
The attributes of the functional traits i.e., leaf area (LA), specific leaf area (SLA), leaf dry matter content (LDMC), leaf water content (LWC), stomatal conductance (Gs), and transpiration (E) followed the order deciduous > evergreen > coniferous.
What are functional traits?
Functional traits are morphological, biochemical, physiological, structural, phenological, or behavioral characteristics that are expressed in phenotypes of individual organisms and are considered relevant to the response of such organisms to the environment and/or their effects on ecosystem properties (Violle et al.
What are traits in plants?
Plant traits, such as leaf size and rooting depth, can affect plant performance and hence, how plants might respond to environmental change. Plant traits can be integrated, or correlated, with a particular functional plant response, such as how plants use water efficiently.
What equation describes photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
How can high temperature negatively affect the rate of photosynthesis?
High Temperatures At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves.
What is a functional trait in biology?
What is a functional trait in ecology?
Definition of Functional trait: Component of an organism’s phenotype that determines its effect on processes and its response to environmental factors.
What traits do all plants share?
What characteristics do all plants share? Nearly all plants are autotrophs, organisms that produce their own food. All plants are eukaryotes that contain many cells. In addition, all plant cells are surrounded by cell walls.
What type of energy does a plant use in photosynthesis?
light energy
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
How do greenhouse gases affect photosynthesis?
Plants consume carbon dioxide—a significant greenhouse gas—in the process of photosynthesis. The reduction of carbon dioxide in the atmosphere has an indirect cooling effect. Plants also cool the atmosphere because they release water vapor when they get hot, a process similar to sweating.
Does humidity affect photosynthesis?
As humidity was increased, photosynthesis increased, transpiration expressed per unit of vapour pressure difference increased, and diffusion resistances became smaller. Reasons for the different behaviour of single leaves and whole plants are suggested.
Why are functional traits important?
Functional traits have been defined as those that affect organismal performance, that is, survival, development (increase in complexity/differentiation), growth (increase in size/mass) and reproduction (Violle et al., 2007).
What is a plant trait?
Plant functional traits, defined as those that influence growth, reproduction, and survival [1,2], are important indices for predicting how plants respond and adapt to changing environments across levels of organization, that is, from organs, to species, and to ecosystems [3,4].
What traits do plants have?
Key characteristics Plants are photosynthetic and contain a green pigment called chlorophyll, which enables plants to convert energy from the sun into food. Plants store their food as starch. Most plants are rooted to one place – some plants can orientate leaves towards the sun and some respond to touch.
What is the function of pigments?
Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear “colorful”. Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths.
What forms of energy do plants produce?
During photosynthesis, “producers” like green plants, algae and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, a carbohydrate or sugar.
