What types of tissues are typical for: a) apple leaf, b) maple bark; c) pine conifers; d) potato tuber; e) poplar trunk?

Apple leaf: outside covered with epidermis – integumentary tissue, between the upper and lower epidermis there is an assimilation parenchyma or chlorensima, which belongs to the main tissues. The veins of a leaf are conductive bundles, which include conductive elements – xylem and phloem. The bundles are surrounded by mechanical tissue.
The pine needles have the same structure. The only difference is that under the epidermis there is a hypodermis (also integumentary tissue), chlorenchyma is folded and there are resin passages.
Maple bark consists of conductive elements of the phloem, the main parenchyma, and bast fibers. If you mean the outer cover, this is the crust, which is a combination of several peridems – the integumentary part.
Poplar trunk – outside the integumentary tissue – periderm or crust, then comes the bark, which has the same structure as the maple bark, then cambium (educational tissue). The wood contains conductive tissue (xylem), the main parenchyma (axial and radial) and wood fibers (mechanical tissue). In the center, the core consists of cells of the main parenchyma.
