Plant physiology is a part of botany that studies how plants work. It looks at how plants grow and function at the smallest levels, like cells and molecules. This helps us understand how plants interact with their environment.

As plants adapted to life on land, they developed special ways to survive, especially in using water and carbon dioxide.
Plant physiology explores various parts of plants and how they work. It covers processes like photosynthesis (how plants make food), getting nutrients, breathing (yes, plants breathe too), moving water and nutrients around, and how plants grow and develop.
This study focuses on the cellular and molecular activities in plants and their role in the environment. Let’s dive deeper into these plant physiology notes to better understand this topic.

Physiology of Plant Parts
Leaves
Leaves are vital parts of plants. They come in various shapes and sizes and play a key role in making food for the plant through photosynthesis.
Stem
The stem gives plants support and shape. It helps plants grow and adapt to different places. Each plant species has its own unique stem structure.
Roots
Roots are the parts of plants that grow underground. They soak up water and nutrients from the soil, making them crucial for plant health.
Xylem and Phloem
These are the plant’s transport systems, like its bloodstream. They move water, sugars, and other essential stuff between the roots, stem, and leaves.

Respiration In Plants
Food essential for life comes from photosynthesis. This process makes energy used to make ATP through glycolysis.
Cellular respiration lets out energy used for ATP synthesis. Aerobic respiration fully breaks down organic things with oxygen, mainly in bigger living things.
To get energy from molecules, they go through steps like the electron transport system and oxidative phosphorylation.
Respiration also has the respiratory quotient. This measures the amount of carbon dioxide let out compared to the oxygen taken in.
