Cell under the microscope
The cell represented in the drawing is most likely to be a fungal cell, because, among other things, it has no chloroplast, a structure present in plant cells that allows them to do the process of photosynthesis.
In the case of fungal cells, they are heterotrophs, i.e they consume the organic compounds they need to produce energy, in opposition to autotrophs plant cells that produce organic compounds from which they take the energy from inorganic compounds, in the process of photosynthesis.
