Plant nutrition and transport
Cells and cell processes
Diffusion, the net movement of molecules and ions from a region of their higher concentration to a region of their lower concentration down a concentration gradient, as a result of their random movement.
Gases
Osmosis, the diffusion of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution), through a partially permeable membrane.
Water
Active transport, the movement of molecules and ions in or out of a cell through the cell membrane against a concentration gradient, using energy from respiration.
Assimilation
Animal nutrition
The assimilation process is the movement of digested food molecules into the cells, becoming part of the cell.
animal's transport system is the circulatory system, same as the xylem and pholem blood vessels transport water, nutrients, sugars and mineral ions
Respiration and the human transport system
animals and plants get their oxigen directly from the surroundings, organisms take oxigen and produce cabon dioxide.
carbon dioxide is a waste product and it must be removed from the organism, organisms have specific areas where the oxigen enters and the carbon dioxide leaves.
one gas is entering and the other leaves, that is because it it called gas exchange
respiration equation C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
Organism and environment
All the energy in an ecosystem originates from the Sun. Some of the energy in sunlight is captured by plants, and used to make food - glucose, starch and other organic substances such as fats and proteins.
Food chain is the sequence which energy, in the form of chemical energy in food, passes from a plant to an animal and then to other animals. And many different food chains link to form a food web.
Producer, an organism that makes its own organic nutrients, usually using energy from sunlight, through photosynthesis.
Human and the environment
chemical fertilizers provide mineral ions to the plants, chemical insecticides or herbicides kills weeds and insects that can affect the growth and development of the plant
as Plants produce oxigen by photosynthesys we should protect them and stop deforestation
biofuels are made of plants in decomposition, it is a good alternative to traditional fuels
biodiesel
bio-oils
bioethanol
Plant transport system
Plants need water, oxigen, carbon dioxyde and mineral ions in order to live. This substances are transported in the Xylem vessels and Pholem vessels of the branches. Xylem transports water and minerals from the roots to the rest of the plant by osmosis. Pholem transpots sucrose and aminoacids in the same way.
transpiration in plants is quite simple, is the loss of water in the plant leaves by evaporation at the mesophill cells in the leaves.
transport of food: plants create carbohydrates by photosyntesis, c
photosynthesis equation
6CO2 + 6H2O + energy --> C6H12O6 + 6O2 =
Gas exchange is the process whereby water vapor and oxygen leave and carbon dioxide enters plant leaves. On balance, therefore, plants use carbon dioxide and produce oxygen. The gases move into and out of the plants through specialized openings located along the lower surface of the leaf those are the Stomata and Guard Cells.
