Plant nutrition meaning
Plants produce their food by taking raw materials from their surroundings, such as minerals, carbon dioxide, water and sunlight.
Types of plants
autotrophs, heterotrophs, and symbiotes
what are autotrophs
an organism that can produce its own food using light, water, carbon dioxide, or other chemical
What are heterotroph
an organism that eats other plants or animals for energy and nutrients
animals nutrition
Nutrients are elements in feed that are used by the animal for growth and production. Nutrients are normally divided into five categories: Water, protein, carbohydrates, minerals, and vitamins.
cells and cell processes
Cellular processes, such as transcription, DNA replication, and DNA repair, are regulated by an intimate and self-reinforcing crosstalk and interdependence between histone-modifying complexes and other histone-modifying activities, such as acetylation, phosphorylation, and methylation.
What are cells
the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body
What are the four cell processes?
Cell Transport, Cell Respiration, Photosynthesis and Cell Division.
What are cellular processes
Cellular processes are the interconnected network of physiological systems that regulate cell function.
What are the 7 main functions of a cell?
Structure and Support.
Growth
Transport. ...
Energy Production. ...
Metabolism. ...
Reproduction
What are the two types of cells
Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
Where is DNA located in cells?
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
What does DNA stand for?
deoxyribonucleic
What is DNA made of
DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C)
Food chains
a linear sequence of organisms through which nutrients and energy pass as one organism eats another
Food web
consists of all the food chains in a single ecosystem
Food chain example
Food web
What is the respiration?
the act or process of breathing
aerobic and anaerobic respiration
Aerobic respiration occurs with oxygen and releases more energy but more slowly.
Anaerobic respiration occurs without oxygen and releases less energy but more quickly.
Lungs diagram
Tarynx
Is your vocal cord
Trachea
Passages that allows air to enter the lungs
Bronchioles
an extension of the trachea and serve as the central passageway into the lungs
Air sacs
grapes at the end of the bronchial branche
Diaphragm
Bronchi
large tubes that connect to your trachea (windpipe) and direct the air you breathe to your right and left lungs.
Bronchus
Thoracic cavity
Respiration in plants
Plants also need energy. The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. This energy is used by the plant for carrying out its various life processes.
What is the respiration system of a plant?
leaves, stems and roots of plants separately exchange gases
What is the equation for respiration in plants?
C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do you explain respiration in plants
What are the transport systems of plants?
xylem. and phloem
What is the transportation of water in plants?
Xylem transports water in plants.
What does the pholem transport
Food and other organic substances
Transpiration
Active transport
Active transport pumps molecules against the concentration gradient.
