What else can I help you with?
What do prokaryotes and eukaryotes have in commmon?
DNA, proteins, plasma membrane
What are eukaryotes surrounded by?
Eukaryotes are surrounded by a double-membrane bound organelle called the nucleus, which contains the cell's genetic material (DNA). The nucleus is separated from the rest of the cell by a nuclear envelope.
Functions of plasma memberane?
Plasma membrane permits the entry and exit of some materials in the cells. Therefore, the plasma membrane is called a selective permeable membrane. Functions of plasma membrane : 1) Diffusion 2) Osmosis 3) Mediated transport
What membrane present in eukaryotes?
Eukaryotic cells have a double-layered membrane called the nuclear envelope that surrounds and protects the nucleus. Additionally, eukaryotic cells have a plasma membrane that encloses the entire cell and regulates the movement of substances in and out of the cell.
Do eukaryotes have cell membrane?
Yes, eukaryotes have a cell membrane. The cell membrane, also known as the plasma membrane, is a semi-permeable barrier that surrounds the cell and regulates the passage of substances in and out of the cell. It plays a crucial role in maintaining cellular integrity and controlling interactions with the external environment.

Do plant cell's animal cell's and bacterial cell's all have a plasma membrane?
Yes, all plant cells, animal cells, and bacterial cells have a plasma membrane. The plasma membrane is a semi-permeable membrane that surrounds the cell and regulates the passage of molecules in and out of the cell.
There are distinct differences and similarities between prokaryotes and eukaryotes what are the similarities?
They both have a plasma membrane and protoplasm. They both have DNA.
Do eukaryotes have cell membrane?
Yes, eukaryotes have a cell membrane. The cell membrane, also known as the plasma membrane, is a semi-permeable barrier that surrounds the cell and regulates the passage of substances in and out of the cell. It plays a crucial role in maintaining cellular integrity and controlling interactions with the external environment.
What evidence supports the hypothesis that the nuclear envelope of eukaryotes arose from infolding of the plasma membrane?
Evidence supporting this hypothesis includes observations that both the nuclear envelope and plasma membrane have a similar lipid composition and protein structure, as well as the presence of nuclear pores that are thought to have evolved from invaginations in the ancestral plasma membrane. Additionally, studies on the dynamics of nuclear envelope formation during cell division provide further support for the idea that the nuclear envelope originated from invaginations of the plasma membrane.
The plasma membrane has a double layer of phospholipids with what dispersed throughout?
Proteins are dispersed throughout the plasma membrane along with cholesterol molecules. These components help maintain the structure and functions of the membrane.
Does plasma membrane produce proteins?
No, the plasma membrane does not produce proteins. Proteins are synthesized by ribosomes in the cytoplasm and then transported to the plasma membrane to carry out various functions such as transport, signaling, and cell adhesion.
How does nutrients enter a cell?
The plasma membrane.
How do phospholipids contribute to the specific functions of the plasma membrane?
Phospholipids in the plasma membrane help create a barrier that controls what enters and exits the cell. They also play a role in cell signaling and maintaining the membrane's structure and flexibility.
