Photosynthesis
What are the two gases exchanged through the stomata?
Oxygen and Carbon dioxide
the cells that forms a tube that allows water to pass through the plant
xylem cells
The type of energy stored because of its movement
kinetic energy
the type of energy stored in an object due to its temperature
thermal energy
atomic number is the same as the number of
protons
What is the part of the plant cell where photosynthesis takes place?
Chloroplast
The mineral responsible for making chlorophyll
magnesium
The type of energy stored because of its position
potential energy
when thermal energy is being transferred from particle to particle. It occurs mainly in solids.
conduction
the period number is determined by the number of
electron shells
What is the function of chlorophyll?
absorbs light for photosynthesis
minerals that helps make proteins for growth and repair
nitrogen or nitrates
potential
when thermal energy causes a substance to rise and expand, which then cools and sinks. It occurs mainly in gases and liquids.
convection
the group number is determined by the number of
electrons in the outer shell
In which layer in a cross-section of a plant leaf can you find a lot of air spaces?
spongy layer
the loss of water vapour through the stomata on the surface of the leaves
transpiration
What do you call the process by which energy spread out to the surroundings into a less useful form?
Energy dissipation
a material which is a poor thermal conductor
insulator
Elements in the same ________________ in the Periodic Table share similar chemical properties.
group.
Write the chemical equation for photosynthesis?
Arrange the parts in correct order to show the pathway of water through a plant.
leaf xylem, root xylem, stoma on the surface of the leaf, stem xylem, root hair cell
root hair cell, root xylem, stem xylem, leaf xylem, stoma on the surface of the leaf
The law of conservation of energy states that
Energy cannot be created or destroyed but just transferred from one energy type to another.
thermal energy is transferred but does not require a matter to travel through
radiation
Explain why elements in the same group have similar chemical properties.
because they have the same number of electrons in the outer shell
