What is the process of plant growth?
The stages that plants go through are from seed to sprout, then through vegetative, budding, flowering, and ripening stages. Similarly, the nutritional needs of people and plants change as they grow.
What is the name of this process of plant growth?
This process is called photosynthesis, which literally means "to put together with light." To produce food, a plant requires energy from the sun, carbon dioxide from the air and water from the soil.
What is the germination process?
germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.
What is plant growth and plant development?
Plant Growth and Development involves study of the control and coordination of processes in cells, organs, and/or whole plants, including, for example, changes in gene expression in response to environmental conditions such as climate change.
What is photosynthesis and transpiration?
Photosynthesis is a plant process that converts atmospheric carbon dioxide into more complex organic compounds, especially sugars, using energy from sunlight. Transpiration. Transpiration is water taken up from the soil and lost through the stomata in the leaves.
What is translocation and transpiration?
*Transpiration is the evaporation of water from the leaves in the form of water vapour whereas translocation is the transportation of synthesized products (sugars)in a plant. *Transpiration always occurs against the gravity while translocation does not always occur against gravity.
What must occur in order for plants to grow?
Plants need five things in order to grow: sunlight, proper temperature, moisture, air, and nutrients. These five things are provided by the natural or artificial environments where the plants live.
What is the difference between photosynthesis and respiration in plants?
The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.
What is translocation in plants?
Translocation is the movement of sugar produced in photosynthesis to all other parts of the plant for respiration and the other processes described above. This occurs in phloem cells.
What is respiration process?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
What is the process of development of seed into seedling called?
The correct option is B germination. The growth of a seed into a young plant or a seedling is called germination.
What is method of planting?
These seven methods include: seed propagation, cutting, layering, division, grafting, budding, and tissue culture technique.
How does kinetic energy stomata and photosynthesis link to temperature and transpiration?
The air just outside of the stomata is therefore less humid, lowering water vapour concentration and therefore maintaining a concentration gradient for the water to diffuse down. Increased temperature increases the kinetic energy of the water molecules and hence they are removed more quickly.
What process takes place in leaves?
Photosynthesis and the Leaf
In plants, photosynthesis generally takes place in leaves, which consist of several layers of cells. The process of photosynthesis occurs in a middle layer called the mesophyll.
What is meant by nutrition class 7?
Answer: Nutrition is defined as the process of obtaining food and utilising it by any organism. Nutrition is one of the key processes of obtaining energy from food.
Which process does the plant need energy to perform?
Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.
