Which cell observed that lack membrane-bound internal organelles?
Prokaryotic cells are observed to lack membrane-bound internal organelles. Unlike eukaryotic cells, which contain structures such as the nucleus, mitochondria, and endoplasmic reticulum enclosed by membranes, prokaryotic cells, such as bacteria and archaea, have a simpler structure. Their cellular processes occur in the cytoplasm or at the cell membrane, without compartmentalization by organelles.
What includes all organelles?
All organelles are included within a cell. Organelles are specialized structures that perform various functions necessary for cell survival and activity, such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus. In eukaryotic cells, these organelles are membrane-bound, whereas prokaryotic cells contain simpler structures without membrane-bound organelles. Together, they contribute to the overall functioning and maintenance of the cell.
How do cytosol and cytoplasm differ?
The chloroplast is an organelle found in animal cells and photosynthetic bacteria. Cytoplasm is the contents of the plant cell, including the nucleus, but excludes the cytosol, the organelles and other liquids
Which organelle does not contain a partially permeable membrane?
The ribosome is an organelle that does not contain a partially permeable membrane. Unlike membrane-bound organelles such as the nucleus or mitochondria, ribosomes are composed of ribosomal RNA and proteins, and they exist freely in the cytoplasm or attached to the endoplasmic reticulum. They function in protein synthesis without the need for a membrane structure.
What is a simple organism without a membrane bound nucleus or organelles?
Prokariyotes are without nucleus.They also lack membrane bound organells.
What organisms are prokaryote?
cytoplasm,ribosomes,cell wall,cell membrane

What is the material in the space between the nucleus and cell membrane?
The material in the space between the nucleus and cell membrane is called cytoplasm. Cytoplasm is a gel-like substance composed of water, salts, and organic molecules that supports and suspends the cell's organelles. It plays a vital role in various cellular processes such as metabolism, transportation of molecules, and cell shape maintenance.

What is a Cell with no membrane bound nucleus or organelles?
A cell without a membrane-bound nucleus or organelles is known as a prokaryotic cell. Prokaryotic cells are typically found in bacteria and archaea, and they contain a single circular chromosome floating freely in the cytoplasm. These cells lack membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.

The chloroplast is an organelle found in animal cells and photosynthetic bacteria. Cytoplasm is the contents of the plant cell, including the nucleus, but excludes the cytosol, the organelles and other liquids
What is a cell without a nucleus or organelles?
Without membrane bound organelles. These cells do have organelles.A prokaryote cell.

What structures can be found in a bird's cell but not in a bacterium?
Bird cells contain organelles such as mitochondria, Golgi apparatus, and endoplasmic reticulum, which are absent in bacterial cells. Additionally, bird cells have a nucleus enclosed within a nuclear membrane, unlike bacterial cells which have a nucleoid region without a nuclear membrane.
Why is the cell's cytoplasm essential to its existence?
Cytoplasm contains and protects all of the organelles inside the cell. It also separates the organelles and other cell parts from the cytosol which breaks down molecules. Cytoplasm is also important because it allows cell organelles to develop and work without interfering with each other.
What cells are prokaryotes?
Prokaryotic Cells are cells that have to have organelles that are not surrounded by a membrane and do have ribosomes. Their DNA is in the shape of a circle. They have no nucleus, the DNA is bunched up in the cytoplasm. The type of cells that are prokaryotic are bacteria and only bacteria cells.
