Answer:

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

Explanation:

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast. Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

Both plant and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles.

Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

When using the DNA center's rest API or GUI interface, northbound APIs are used.

In contrast, a southbound interface allows a higher-level component to send commands to lower-level network components. A northbound interface is an application programming interface (API) or protocol that enables communication between lower-level and higher-level or more central network components.

The communication channel between the applications and the SDN controller is provided by northbound APIs. Applications can inform the network of their resource requirements (data, storage, bandwidth, etc.), and the network can communicate what it has or deliver the resources requested. Numerous applications are supported by these APIs.

Genetics-The inherited characteristics you get from your family's lifeline of DNA.

Explanation:

Not all intercellular signals require transduction, and one such signal that can be processed without transduction is the direct physical contact between cells. When cells come into direct contact, they can exchange information and communicate through cell-to-cell interactions without the need for signal transduction pathways.

Cellular interactions involving direct contact play a significant role in various biological processes. For example, during development, cell adhesion molecules on the surface of cells facilitate cell-cell recognition and binding, allowing cells to adhere to each other and form tissues and organs. Similarly, immune cells can recognize foreign pathogens through direct contact and initiate immune responses. Unlike other signaling mechanisms that involve the conversion of an extracellular signal into an intracellular one through signal transduction pathways, direct cell contact enables immediate and precise communication between neighboring cells. It bypasses the need for extracellular signaling molecules and transduction processes, allowing for rapid response and coordination of cellular activities. Understanding the different modes of intercellular communication, including both transduction-dependent and direct contact signaling, provides insights into the complexity and versatility of cellular communication networks. Further exploration of these signaling mechanisms can contribute to our knowledge of various physiological and pathological processes.

Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the spring when they provide energy for new growth.

hope this helps ☆☆☆

The leaves and rhizomes of the plant are found to act both as a source and a sink when growing and when they perform photosynthesis.

Source organs are the organs which provide a net uptake of resources while sink organs are the organs which have a net drawdown of resources in the plant. Molecular mechanisms which are responsible for the regulation of the relationship between the sources and sinks. These molecular mechanisms include both the carbon and nitrogen-containing metabolites, plant hormones and genes.

Some organs in the plant are found to act both as a source and a sink. Leaves of the plant are sinks when growing and as source when photosynthesizing in the presence of sunlight during daytime.

Cell biology: Parts of the cell, Prokaryotic and Eukaryotic Cells.

The Eukaryotic cells are those that have their genetic material within a nucleus. There are three basic types of eukaryotic cells based on their structure: plant cells, animal cells, and fungal cells.

Some of the distinct characteristics of plant cells are:

• The presence of a, cell wall ,composed of ,cellulose, hemicellulose, and pectin,, gives extra protection and support to the cell, and it helps to maintain the shape of the cell.

• Special pathways of communication are called ,plasmodesmata,, which go through the cell wall.

• A large central, vacuole,, that serves as, storage, of water and other substances.

• Chloroplasts,, ,produce sugars, using the carbon dioxide available and the energy of sunlight.

They also have other structures common to all eukaryotic cells, such as mitochondria and Golgi apparatus.

Now let's compare this information to the statements:

• Statements a ,and ,b, are, false ,because is the chloroplast that makes sugar using sunlight

• Statement c is true,, because the vacuole stores many substances, and plant cells also have mitochondria to break down sugar.

• Statement d is true, because plants and animal cells are two types of eukaryotic cells, and this means they have a nucleus.

The important enzyme in Calvin cycle is ibulose bisphosphate carboxylase (RuBisCO).

The Calvin cycle is important because it performs chemical reactions by plants to fix carbon from CO2 into three-carbon sugars. Then, plants and creatures can transform these three-carbon compounds into amino acids, nucleotides, and more complex sugars like starches.

Reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules is called Calvin cycle. Carbon fixation occurs  During the first phase of the Calvin cycle.

The carbon dioxide combines with ribulose 1,5-bisphosphate to form two 3-phosphoglycerate molecules (3-PG) and the  enzyme that catalyzes this reaction is RuBisCO. It is the enzyme  that is responsible for photosynthetic carbon assimilation in catalyzing the reaction of CO2 with ribulose 1,5‐bisphosphate (RuBP) to form two molecules of d‐ phosphoglyceric acid (PGA).
