perform more complex functions and exhibit greater diversity in their cellular activities compared to prokaryotes. Organelles like mitochondria and chloroplasts enable eukaryotic cells to carry out specialized processes such as energy production and photosynthesis. The nucleus also provides a protected environment for DNA, allowing for more efficient transcription and regulation of gene expression.

What are cells with a nucleus and membrane bound organelles?
Cells with a nucleus and membrane-bound organelles are considered eukaryotic cells. Eukaryotic cells are more complex than prokaryotic cells and are found in plants, animals, fungi, and protists. The presence of a nucleus allows for compartmentalization of functions within the cell.
What can eukaryotes do that prokaryotes can't?
Eukaryotes can perform more complex cellular functions due to their compartmentalized organelles, such as the nucleus, mitochondria, and endoplasmic reticulum. Prokaryotes lack these organelles and therefore have limited intracellular organization and function. Eukaryotes can also undergo sexual reproduction, a process that allows for genetic diversity through meiosis and fertilization, which is not typically found in prokaryotes.
What makes up eukaryote?
Eukaryotic cells contain a defined nucleus that houses the genetic material (DNA), as well as other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Eukaryotes also have linear chromosomes organized within the nucleus. Additionally, eukaryotic cells typically have a cytoskeleton that helps maintain their shape and allows for cellular movements.
What do the cells of eukaryotes have?
Eukaryotic cells have a well-defined nucleus that houses the genetic material (DNA) and membrane-bound organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus. These cells also have a complex cytoskeleton that provides structure and allows for cell movement.
Cells in which nucleus and cytoplasm are pushed against a cell membrane?
These cells are likely epithelial cells, which are specialized for protection, absorption, and secretion. The nucleus is typically located near the base of the cell due to the presence of organelles in the apical cytoplasm that help in these functions. The arrangement of nucleus and cytoplasm allows for efficient communication and transportation of substances across the cell.

What major advantage does the presence of organelles offer eukaryotic cells?
The presence of organelles in eukaryotic cells allows for compartmentalization of different cellular functions. This specialization enables more efficient and diverse cellular processes compared to prokaryotic cells. Organelles also provide structural support and protection to the cell.
What do the membranous compartmentalization of eukaryotic cells require?
Membranous compartmentalization in eukaryotic cells requires the presence of membrane-bound organelles, such as the nucleus, endoplasmic reticulum, Golgi apparatus, and mitochondria. This compartmentalization allows for specific functions to be localized within distinct areas of the cell, enabling efficient and specialized cellular processes. The maintenance of these compartments also requires the presence of selective permeability in the membranes, ensuring proper communication and transport between organelles.
Why do eukaryotes have a nucleus and a prokaryote does not?
Eukaryotes have a nucleus because their genetic material needs to be separated from the rest of the cell to protect it and regulate gene expression. Prokaryotes, on the other hand, have their genetic material dispersed in the cytoplasm because they are simpler organisms with less complex regulatory needs.
What cell lacks nuclei?
A prokaryotic cell has no nucleus. Instead of being stored in the nucleus, the cell's DNA is found freely in its cytoplasm. This is in contrast to eukaryotic cells, whose DNA is stored in the nucleus. All complex organisms are eukaryotes. Prokaryotes include bacteria.
Why do eukaryotes have membrane-bound organelles?
Eukaryotes have membrane-bound organelles because these compartments allow for different specialized functions to be carried out within the cell. The membranes provide a barrier that helps maintain distinct environments for specific cellular processes, improving efficiency and organization.
Does a red blood cell have organelles?
No, red blood cells lack organelles such as a nucleus, mitochondria, and endoplasmic reticulum. This allows them to carry oxygen more efficiently as they have more space to carry hemoglobin.
What 2 things do red cells lack compared to white cells?
Red blood cells lack a nucleus and organelles, such as mitochondria, which are present in white blood cells. This allows red blood cells to have more space to carry oxygen and carbon dioxide through the bloodstream efficiently.
