A vacuole is a fluid-filled organelle found mostly in plant cells and fungi. Vacuoles perform a number of important functions including detoxification.
What is the fluid in the cell that fills in the space?
Cytoplasm
is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules.
Which organelle is a fluid which fills spaces in the cell and keeps organelles in place?
Inside the cell there is a large fluid-filled space called
the cytoplasm
, sometimes called the cytosol. In prokaryotes, this space is relatively free of compartments. In eukaryotes, the cytosol is the “soup” within which all of the cell's organelles reside.
What organelle holds cells organelles in place?
| A B | Organelle Structure that performs a specific function within the cell | Cytoplasm The fluid-like substance found inside the cell. Hold the organelles in place. | Nucleus Control center of the cell. Contains two membranes and DNA. Found in Eukaryotic cells. |

What is turgor pressure and how does it relate to the health of a plant?
Turgor, Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor is
what makes living plant tissue rigid
. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.
Which organelle is responsible for making proteins?
Ribosomes
. Ribosomes are the protein factories of the cell.
Which organelle is in charge of releasing energy?
Mitochondria
are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What does interstitial fluid consist of?
Interstitial fluid contains
glucose, salt, fatty acids and minerals such as calcium, magnesium and potassium
. The nutrients in interstitial fluid come from blood capillaries Interstitial fluid can also hold waste products which result from metabolism.
What do plant cells have that animal cells do not?
Plant cells have a cell wall, but animals cells do not. … Plant cells have
chloroplasts
, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
What keeps all the organelles in place?
The cytoskeleton
is an important, complex, and dynamic cell component. It acts to organize and maintain the cell's shape; anchors organelles in place; helps during endocytosis (the uptake of external materials by a cell); and moves parts of the cell in processes of growth and motility.
What is a jelly like substance that holds organelles in place?
The
cytoplasm
, or cell fluid, is made up of a jelly-like substance (cytosol) and within that, the organelles. The organelles are the cell's organs. The cytoplasm is often colourless and is surrounded by the cell membrane which keeps the contents within the cell.
Are ribosomes site of protein synthesis?
Ribosomes are the
sites in a cell in which protein synthesis takes place
. … Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.
Why is turgidity useful to plant cells?
In a biological context, turgidity helps to explain as
to how plant cells are able to stand upright despite the lack of a skeletal structural framework
that animals have. Also, it confers rigidity to plants. Thus, the distention of cells is a normal feature among plants.
Is turgor pressure positive or negative?
It is also known as wall pressure or turgor pressure. The pressure potential is usually positive in a turgid plant cell. It is
negative in xylem
tissues and is a potential pressure in a transpiring plant.
How does turgor pressure happen?
Generally, turgor pressure is
caused by the osmotic flow of water
and occurs in plants, fungi, and bacteria. … The pressure exerted by the osmotic flow of water is called turgidity. It is caused by the osmotic flow of water through a selectively permeable membrane.
Which two organelles are most important in the production of proteins in a cell?
Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and
ribosomes
, the cellular organelles responsible for protein synthesis.
