What features of the plant leaves might affect the net rate of photosynthesis?
Several factors can affect the rate of photosynthesis:
- light intensity.
- carbon dioxide concentration.
- temperature.
What features of a leaf help with photosynthesis?
The adaptations of leaf for photosynthesis are:
- Large surface area for maximum light absorption.
- The presence of chlorophyll containing chloroplast.
- Thin structure– Short distance for carbon dioxide to diffuse into leaf cells.
- The stomata that allow carbon dioxide to diffuse into the leaf and oxygen to diffuse out.
What affects plant photosynthesis?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
What caused the leaf disks to float?
Leaf disks float, normally. When the air spaces are replaced with water the overall density of the leaf disk increases and the disk sinks. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy–causing the disks to rise.
What environmental variables might affect the net rate of photosynthesis quizlet?
How do leaves carry out photosynthesis?
Plants use their leaves to make food. During photosynthesis, plant leaves take in carbon dioxide from the atmosphere. Using the energy from sunlight, this is combined with water drawn up from the roots to make glucose. Oxygen is also produced in this chemical reaction and exits the leaves into the surrounding air.
How do plants increase photosynthesis?
Several strategies for improving photosynthesis have recently been proposed, such as reducing light-harvesting antenna size, introducing components of algal CO2-concentrating mechanisms, engineering of photorespiratory bypasses, and accelerating recovery from photoprotection (NPQ).
What environmental factors affect the rising of the leaf disks?
As photosynthesis proceeds oxygen is released into the interior of the leaf, which changes the buoyancy–causing the disks to rise. Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect measurement of the net rate of photosynthesis.
What are five factors that affect the rate of photosynthesis?
The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors. 1. Effect of Carbon dioxide: Being one of the raw materials, carbon dioxide concentration has great effect on the rate of photosynthesis.
