What happens at noontime in the leaf of a plant?
Photosynthesis occurs only in the mesophyll layers of plant leaves and, in some instances, in mesophyll cells in the stem. Mesophyll cells are sandwiched between the leaf’s upper and lower epidermis and contain numerous chloroplasts, where photosynthesis takes place. Chloroplasts are incredibly small.
Why is the root of a plant unable to absorb mineral salts from the soil if it is given a poison that prevents respiration?
Since the poison prevents respiration from occurring in the root, the energy needed to move mineral salts from the soil through the membranes of the root cells into the root cannot be made.
What is photosynthesis question answer?
Answer: Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials.
Does the size of a leaf affect photosynthesis?
Yes, larger the leaf size, higher is the rate of photosynthesis. Larger leaf size has a broader surface area with more chloroplasts, absorbs more light from the sun and more number of stomata present on the surface of the leaves, which play a crucial role in gaseous exchange during the process of photosynthesis.
How are minerals transported into the roots of a plant?
Root hair cells Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
What is photosynthesis for 8th class?
Photosynthesis is the physico-chemical process by which plants can convert light energy into chemical energy, in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water. Photosynthesis requires carbon dioxide, sunlight, water and chlorophyll as its basic raw materials.
