A lysosome (/ˈlaɪsəˌsoʊm/) is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules.

The nuclear envelope separates the contents of the nucleus from the cytoplasm and provides the structural framework of the nucleus. The nuclear membranes, acting as barriers that prevent the free passage of molecules between the nucleus and the cytoplasm, maintain the nucleus as a distinct biochemical compartment.

Organelles composed of membrane-bound sacs, canals, and vesicles for tubular transport. Spherical organelle that contains chromatin and nucleolus. Ribosome. Small RNA-containing particles for the synthesis of proteins.

The Nuclear Envelope – The nuclear envelope is a double-layered membrane that encloses the contents of the nucleus during most of the cell’s lifecycle. The space between the layers is called the perinuclear space and appears to connect with the rough endoplasmic reticulum.

Inside the cell there is a large fluid-filled space called the cytoplasm, sometimes called the cytosol. In prokaryotes, this space is relatively free of compartments. In eukaryotes, the cytosol is the “soup” within which all of the cell’s organelles reside. It is also the home of the cytoskeleton.

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.

(a) Nuclear membrane, chloroplast, mitochondria, microtubules and pili are absent in prokaryotic cells.

Prokaryotes are organisms whose cells lack a nucleus and other organelles. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

If cell wall is absent in plant cell then all the functioning of all the cell organelles present inside the cell would be affected as diffusion of various substances would not occur. Due to absence of turgor pressure, the cell will not bear the concentration of solution (either hypertonic or hypotonic) and will burst.
