LIFE SCIENCE

Detailed explanation-1: -Eukaryotes such as fungi, protozoa, plants, and animals, and thus we humans, have cells with complex structure (Figure 1) with internal membranes and membrane-bounded organelles. These include the chromosome-containing nucleus surrounded by a nuclear envelope consisting of two membranes.

Detailed explanation-2: -A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions.

Detailed explanation-3: -Eukaryotic cells contain a variety of internal membrane-bound organelles that are not a part of the endomembrane system. These include mitochondria, chloroplasts, lysosomes, peroxisomes, vacuoles, and vesicles.
