What is plant physiology in biology?
Plant physiology is the study of plant function and behaviour, encompassing all the dynamic processes of growth, metabolism, reproduction, defence, and communication that account for plants being alive (Salisbury & Ross, 1992; Baluška et al., 2006; Scott, 2008).
What is photosynthesis in Igcse biology?
Photosynthesis Theory Photosynthesis is an endothermic reaction in which energy from sunlight is transferred to the chloroplasts in green plants. Green plants use this energy to make the carbohydrate glucose from the raw materials carbon dioxide and water. At the same time, oxygen is made and released as a waste …
What do plants need for their nutrition Igcse?
If asked for the raw materials required for photosynthesis, the answer is carbon dioxide and water.
Is plant physiology hard?
Plant physiology is more tricky than zoology and needs more dedication and time. It’s best if you have notes . They can be a great tool to revise . With NEET around the corner , it is also better to stick to ncert if you don’t have other resources.
What are the 5 physiological processes in plants?
At the smallest scale are molecular interactions of photosynthesis and internal diffusion of water, minerals, and nutrients. At the largest scale are the processes of plant development, seasonality, dormancy, and reproductive control.
Which chapters are included in plant physiology?
Chapters are 1) Transport in Plants 2) Mineral Nutrition 3) Photosynthesis in Higher Plants 4) Respiration in Plants 5) Plant Growth & Development 6) Sexual Reproduction in Flowering Plants 7) Reproduction in Organisms.
Where is starch stored in plants Igcse?
Starch is stored in chloroplasts where photosynthesis occurs so testing a leaf for starch is a reliable indicator of which parts of the leaf are photosynthesising.
What are the 4 minerals plants need?
Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
Why is potassium needed in plants GCSE?
Poor plant growth may be due to a deficiency in one or more minerals….Mineral requirements.
| Mineral | Element supplied | Why needed |
|---|---|---|
| Potassium compounds | Potassium, K | Potassium is needed in enzymes involved in respiration and photosynthesis |
Who is father of plant physiology?
Julius Sachs (1868): The father of plant physiology.
What are the 6 physiological processes in plants?
Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations.

What is source and sink in plant?
The photosynthetically active parts of a plant are referred to as the source. The areas of active growth and areas of storage are referred to as sink in plants.
What are sinks in plants?
The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks. Sinks include areas of active growth (apical and lateral meristems, developing leaves, flowers, seeds, and fruits) or areas of sugar storage (roots, tubers, and bulbs).
