<span> The answer is <span>centriole</span>
The majority of cells have mitochondrion as they need them for their respiration. Chloroplast is the structure plants use to produce their organic matter, the vacuole is very developed in plant cells and is central where as you usually have many vacuoles in animal cells, and the centriole is usually present in animal cells only as well as the wall of cellulose that wraps up the plant cell.</span>
Answer:
The speed at which the reactants change to products over a given time.
Explanation:
A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.
Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:
reactants → products
Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>
According to the temperature and other parameters, the reaction rate can increase or decrease.

Answer: A - Uptake of food and water by plants
