Answer:
Systematically describe; assess relations between variable. Option A
Explanation:
First, we will fill in the gap in the question, check below;
''Whereas observational research is designed to SYSTEMATICALLY DESCRIBE behavior, correlational research is designed to ASSESS RELATIONS BETWEEN VARIABLE''.
In order to analyze a particular subject there is a part of research techniques to be used in which the analyst just have to observe, the research method or technique for that is called the Observational research. The person observing or the analyst can also be a participant that is part of the subject and still observe.
When you take two things -- variables and you compare and contrast them, you are already using the Correlation research method.
Plant cells need Chlorophyll and a Cell wall.
<span><span>Cell Wall: </span>Plant cells are actively involved in water transportation, and thus plant cell wall ensures that the cell does not burst due to over expansion as water flows in (internal turgor pressure). It helps to maintain the shape and osmolarity of the cells and acts as defense against pressure due to inflow of water. Other than that they need cell walls to protect them from pathogens

<span><u>Chlorophyll:</u></span><u /> <span>The leaves contain a pigment called </span>chlorophyll<span>, which colors the leaves green. </span>Chlorophyll<span> can make food the </span>plant<span> can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
