Q. What advantages do organelles give eukaryotic cells?
Membrane-bound organelles offer several advantages to eukaryotic cells. First, cells can concentrate and isolate enzymes and reactants in a smaller volume, thereby increasing the rate and efficiency of chemical reactions.

Q. What advantages does a eukaryotic cell gain by having a nuclear envelope?
Nuclear envelope – how it helps. The nuclear envelope keeps the contents of the nucleus, called the nucleoplasm, separate from the cytoplasm of the cell. The all-important genetic material, mainly the DNA is kept separate and relatively safe from the chemical reactions taking place in the cytoplasm.
Q. What advantage did having Mitochondria give eukaryotes?
These folds provide a greater surface area for energy-producing reactions to occur, allowing the mitochondria to produce a substantial supply to its host. That gives eukaryotes a major advantage over their prokaryotic peers: with more available energy, they can afford to have more genes.
Q. What is the advantage of cellular organelles like mitochondria?
Increases surface area for more chemical reactions to take place. For example, the folded membranes in mitochondria allow more energy to be produced through chemical reactions.
Q. What are two examples of organisms with prokaryotic cells?
Examples of prokaryotes are bacteria, archaea, and cyanobacteria (blue-green algae).
Q. What is the clear fluid inside a cell?
chapter 7-eukaryotic cell structure and function
| A | B |
|---|---|
| cytoplasm | the clear fluid inside the cell |
| nucleus | organelle that manages cell functions in the eukaryotic cell |
| chloroplast | contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color |
Q. What is the fluid matrix inside the cell is called?
The fluid matrix filling the cell is cytoplasm. Cytoplasm is the jelly-like substance present between the cell membrane and the nucleus. It holds organelles and provide site for the various biochemical reactions.
Q. What fills the empty space in a cell?
Cytosol is the jelly-like fluid that fills the space between cell organelles. It also plays a role in keeping the cell’s structure.
Q. What structure fills the space between two cells?
A nonliving material, called the intercellular matrix, fills the spaces between the cells. This may be abundant in some tissues and minimal in others. The intercellular matrix may contain special substances such as salts and fibers that are unique to a specific tissue and gives that tissue distinctive characteristics.
Q. What is the gap between cells called?
Anatomical terminology. Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells.
Q. How much space is there between cells?
The paracellular breadth between cell membranes juxtaposed by tight junctions appears to be <5 nm. In a gap junction the intercellular space is reduced from 25 nm to a ~2-4 nm wide paracellular space. The width of the intercellular space between cells with desmosomes between them is very wide (about 30 nm).
Q. What do you notice about the size of the cell?
Cell size is limited by a cell’s surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell’s function is determined, in part, by its shape.
Q. How does a chromosome look like?
The image of a chromosome as an X-shaped blob is familiar to many. But perhaps not everyone knows that this microscopic portrait of a chromosome shows a structure that occurs only transiently in cells, at a point when they are just about to divide by undergoing a process called mitosis.
