What is an animal cell?
An animal cell is a type of eukaryotic cell that is the basic structural and functional unit of animals. It contains various organelles such as the nucleus, mitochondria, and ribosomes that carry out specific functions to support the cell's survival and activities.
What two things do ALL cells have in common?
Hey there, The question likely will be relating to Eukaryotic and Prokaryotic cells. Eukaryotic Cells are plant cells and animal cells (any cell with membrane bound organelles) and Prokaryotic Cells are cells such as bacteria. Either way, every one of these cells should share common structures which include a cell membrane and ribosomes. They should all contain cytosol and some type of DNA, whether this is inside a nucleus (plant and animal cells) or free floating in the cytoplasm (prokaryotic cells). The 'cell theory' also states that: 1. All cells are the smallest 'living' organisational unit 2. Every cell will come from a pre-existing cell (via cellular reproduction) 3. All 'living' things are made up of cells. ---> But the simple answer you are probably looking for is a 'cell membrane' and 'ribosomes' <---
What are three characteristics of Cells?
Animal cells are eukaryotic in nature, having a well-defined membrane-bound nucleus. Besides a nucleus, they have a cell membrane, mitochondria, endoplasmic reticulum, ribosomes and Golgi bodies/ Apparatuses, centrioles, lysosomes, and cytoplasm.
What is the meaning of 70S ribosomes in prokaryotes?
70S refers to the rate of sedimentation of the ribosome in a centrifuge. You can almost think of it as a unit of size. The "S" is a unit of measurement called the Svedberg unit. Ribosomes contain two subunits. In prokaryotes, these subunits are 50S (large) and 30S (small). The total ribosome with both subunits is 70S in prokaryotes. (Notice that 30 + 50 = 80 and not 70. Remember this is not size and the rate of sedimentation is less when the subunits are bound then when they are separated.) Eukaryotic cells have 80S ribosomes: 60S (large) and 40S (small) subunits.
What basic protein forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes?
Histones are the basic proteins that form the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes. These proteins help to package and condense the DNA within the cell nucleus.

What is the purpose of a eukaryotic cell?
The eukaryotic cell is the basic unit of life in eukaryotic organisms. It has organelles that are involved in the synthesis of lipids and proteins. The cell bears genetic material in the nucleus, and mitochondria to generate energy in form of adenosine triphosphate (ATP).

Jesse was looking at a cell through a microscope and saw mitochondria and cell membranes what could Jesse say about the cell?
Jesse could say that the cell is likely a eukaryotic cell, as mitochondria are organelles found in eukaryotic cells. The presence of cell membranes suggests that the cell is a structural unit of a living organism, responsible for maintaining its integrity.

A tiny organ in a cell is called?
A tiny organ in a cell is called a cell organelle. There are several such organelles in the cells such as cell wall, cytoplasm, nucleus, vacuoles etc. Cell organelles perform different functions to make the cell as a unit of life.
What are facts about ribosomes?
Here are some facts: Ribosomes are small organelles found in the cells of all life forms. They are quite small, only AAA few hundred nanometres across. It has been theorized that ribosomes were once independent life forms, reproducing on their own, until other chemicals such as carbohydrates and DNA were brought into the fold at AAA later time. Ribosomes are composed of rRNA and other proteins. Their main function is to produce a variety of proteins from simple genetic instructions which propagate outwards from the cellular nucleolus in the form of messenger RNA. Ribosomes float in the cytoplasm of a cell or bind to the endoplasmic reticulum, ribbon like structures found inside of the cell. quick facts(written by myself) ¢Ribosome's are the workbenches where proteins get manufactured¢Ribosome composes 25% of cell mass¢ They get their name from their size.¢A bacterial cell contains a few thousands of ribosome's, although a human cell has a few million¢Ribosome's are made up of two subunits, the large and small subunit.¢When the two units are docked together with a special information unit called messenger RNA, they make proteins
What is the smallest unit that can carry on the processes of life?
The smallest unit that can carry on all the processes of life is a cell. The cell membrane is made of phospholipids.
The components of ribosomes are formed by?
The components of ribosomes are formed by a type of RNA called ribosomal RNA (rRNA), along with proteins. These two types of molecules come together to create the functional unit of ribosomes that play a central role in protein synthesis within cells.
