Solution

The correct option is D

Prokaryotes do not have a nucleus.


The correct options are B and D.

Explanation for the correct options:

Option D:

  1. A single-celled organism known as a prokaryote is devoid of a nucleus and other membrane-bound organelles.
  2. Animals known as prokaryotes lack a nucleus and other organelles in their cells.
  3. Bacteria and archaea, two separate groupings of prokaryotes with supposedly independent evolutionary histories, are separated.
  4. The majority of prokaryotes are tiny, single-celled creatures with a straightforward structure.

Option B:

  1. Every organ is made up of two or more tissues, which are collections of comparable cell types that collaborate to carry out particular functions.
  2. Epithelial tissue, connective tissue, muscle tissue, and nerve tissue are the four main tissue types that make-up humans and other big multicellular organisms.
  3. The statement is accurate in this instance because an organ system is made up of multiple organs that work together to achieve a shared goal.


Explanation for the incorrect options:

Option A:

  1. A tissue is structurally organized to perform a specific function by a group of similar or different cells.
  2. An organ is a collection of tissues that have been carefully structured so that they can cooperate to carry out particular tasks.

Option C:

  1. A vacuole is an organelle that is bound by two membranes.
  2. It can be found in the cells of fungi, plants, and animals.
  3. In contrast to animal cells, the vacuole in a plant cell is much larger.
  4. They contain liquid inside.

Final answer: The correct statements are an organ consists of similar cells and prokaryotes do not have a nucleus.
