The correct answer is Collenchyma.
The collenchyma cells are lengthened cells with uneven thick cell walls, which are responsible for structure and support. Their thick walls comprises of the compounds pectin and cellulose. These cells are generally found below the epidermis, or the outer layers of cells in leaf veins and in young stems.
These cells provide structural support, mainly in developing leaves and shoots. The strength of the tissue comes from these condensed cell walls and the longitudinal meshing of the cells.

So, the required answer is :
=》A. <em><u>Water and minerals</u></em>
the answer is b. energy and matter can enter and leave.
Answer:
Cyanobacteria are microscopic organisms found in all kinds of water. They are single-celled organisms and produce their own food from sunlight via photosynthesis. Cyanobacteria are important to evolution because they developed the oxygen atmosphere we live in by producing waste from cyanobacteria. Plants also evolved from Cyanobacteria.
Carolus Linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. One of his contributions was the development of a hierarchical system of classification of nature. Today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
