Depends on how big it is, where it is and what kind of plant it is.

Any plant will produce more O2 on a sunny day than a cloudy day, since more sunlight hitting the plant means more energy to produce more oxygen via photosynthesis. Photosynthesis is a biochemical process that turns sunlight, water, and carbon dioxide into sugar, oxygen, and ATP.
Roots anchor the plant in the soil, providing stability against strong winds. Additionally, roots help to absorb water and nutrients from the soil, which can support the plant in times of stress, such as during windy conditions.
Oxygen can be greatly depleted from ocean water by heavy plant growth through the process of photosynthesis. Plants use up the dissolved oxygen during the day and can lead to oxygen-deprived conditions at night, especially in densely vegetated areas like coral reefs.
A plant's stomata are generally open during the day to allow for the exchange of gases like carbon dioxide and oxygen needed for photosynthesis. They are closed at night to prevent water loss through transpiration when photosynthesis is not occurring.
Plants are living things and their metabolism constantly 'burns' food using Oxygen and producing CO2, they do this all the time, day and night.However, during the day plant is bombarded by photons (i.e. light). The light allows the plant to photosynthesise, turning CO2 and water into Hydrocarbons for food and releasing Oxygen.The amount of Oxygen produced is surplus to its metabolic requirements and is therefore released into the atmosphere.At night photosynthesis closes down because there is no light so the plant consumes oxygen and releases CO2 like animals.However, please note that there are a special group of plants (plants that live in desert climates) that have modified how and when they take up CO2.In this special group of plants (called CAM plants) the CO2 enters the plant at night and is stored by the plant in special structures. This stored CO2 is then used for photosynthesis during the day but the plant takes in no new CO2 during daytime.The CAM plants do this so as to prevent water loss during the hot daytime hours.
On average, a plant can absorb about 1/3 of a pound (150 grams) of carbon dioxide in a day.
From the air around it. During the day, plants absorb oxygen from the air. At night - they absorb carbon dioxide.
Plants need both oxygen and carbon dioxide to make food. During the day, the plant absorbs carbon dioxide from the bottom of the leave and creates food using sunshine. At night, the plant needs to absorb oxygen to burn the sugars it created.
Oxygen. Because the plants need sunlight to produce it.

On a sunny day because there is more sun to help produce oxygen
On a sunny day because there is more sun to help produce oxygen
A plant would produce more oxygen on a sunny day because it relies on sunlight for photosynthesis, the process by which it produces oxygen. Cloudy days reduce the amount of sunlight available for photosynthesis, leading to lower rates of oxygen production.
On a sunny day because there is more sun to help produce oxygen
On average, a plant can produce around 5-10 grams of oxygen per day through photosynthesis. This amount can vary depending on factors like the plant species, size, growth conditions, and sunlight availability.
Plant waste product.
Oxygen is a good example.
