Answer: The tracheids have important functions in the plant.
Explanation: The mechanical support is provided by the lignified walls of tracheid cell. the helps in other functions of the plant such as transporting water and getting the solute from the root to the stem and eventually the leaf of the plant.
The tracheids are most useful in the gymnosperms where elements need to be transported.
Identifying a tracheid in a cross section is quire easy as the tracheid cells fit into each other neatly and piled up similarly and have identical shapes as well which makes them obvious from other cells.
The two examples of tracheid plans could be
The most common thing that could be found in traceid plant is that this cells are mainly present for transporting either water other solutes in the plant body.
Convergent evolution in my understanding is the independent evolution of similar features in species of different lineages.
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
Hello!
I believe the correct answer would be: Nonheme Iron.
I really hope my answer helped you! :)
The correct answer is A - leaves that close when touched.
The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.
The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them.
This type of movement is called thigmonasty which is a non directional plant response to being touched.
