Plant growth and nutrition Quiz

During the day, the rate of photosynthesis is much higher than the rate of cellular respiration. Consequently, plants produce and release far more oxygen into the atmosphere than they consume for their own respiration.

Elaborated sap, which consists of water and synthesized organic nutrients like sucrose, is distributed throughout the plant via phloem vessels. Xylem vessels transport raw sap (water and minerals), while stomata are pores for gas exchange.

Photosynthesis requires sunlight as the primary energy source to drive the chemical reaction. This light energy is captured by chlorophyll, the green pigment located inside the chloroplasts of plant cells.

Raw sap, which consists of water and mineral salts, is absorbed by the roots and travels to the leaves. There, it combines with carbon dioxide absorbed from the air and, using sunlight, transforms into elaborated sap (the plant's food).

Stomata are microscopic pores found mainly on the epidermis of leaves. They regulate gas exchange (taking in carbon dioxide and releasing oxygen) and control water loss through transpiration.

Photosynthesis is the chemical process by which green plants use sunlight to synthesize nutrients from carbon dioxide and water. During this process, raw sap is converted into nutrient-rich elaborated sap.

Raw sap is the term used for the inorganic solution of water and mineral salts absorbed by plant roots from the soil before it undergoes photosynthesis.

Like all living organisms, plants perform cellular respiration to break down food for energy. During respiration, they take in oxygen and release carbon dioxide.

Plants are autotrophic organisms, meaning they produce their own food (sugars) using light energy from the sun during photosynthesis.

Nutrients, in the form of raw sap (water and minerals) and elaborated sap (organic food), are transported throughout the plant via specialized vascular tissues called xylem and phloem.

Plants absorb water and mineral salts from the soil through their roots, and they take in gases like carbon dioxide and oxygen from the air through their leaves.

While plants require light, water, and air, most plant species thrive best in mild temperatures. Extreme heat or freezing cold can disrupt their metabolic processes and damage their tissues.

Photosynthesis requires light energy, water, carbon dioxide (from the air), and mineral salts. Soil itself is not strictly necessary as long as the plant has access to water and dissolved minerals, as demonstrated in hydroponics.

Plants are autotrophs, which means they can synthesize their own food using inorganic substances and light energy. Animals are heterotrophs and must consume other organisms to obtain energy.
