Are plant cells prokaryotic or eukaryotic

Biology
1 answer:
natali 33 [55]3 years ago
7 0

Answer:

Plant cells are eukaryotic.

Explanation:

Plant cells are eukaryotes, as are animal cells.  This is because plant cells include many organelles in their cytoplasm, which are membrane-bound structures that perform specific functions.  For example, plant cells contain the endoplasmic reticulum, Golgi apparatus, and typically a large central vacuole for storage.  Prokaryotes, such as bacteria, lack these organelles.  In addition, plant cells have a cell wall that provides structure and chloroplasts (the organelle responsible for photosynthesis in plants) that distinguish them from eukaryotic animal cells.

Hope this helps!

Explain the process of how air flows through the Respiratory System? In three sentences.
hjlf

Answer:

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.

The zone of leaching is the area in which ________. weathered bedrock forms a soil horizon organic matter gathers to create a so
Ksenya-84 [330]

Answer:

minerals are dissolved and removed from soil

Explanation:

The zone of leaching is the segment of the soil profile, where nutrients or minerals are dissolved to form soluble minerals, which are later carried by percolating water that penetrates the soil, and moved downwards as the water travels through the soil profile. This zone where minerals are dissolved and removed from the soil, is what we refer to as the zone of leaching.

An operon is a:_________.
xeze [42]

Answer:

b. region of DNA consisting of the promoter, the operator, and coding sequences for structural proteins.

Explanation:

Operon is a segment of DNA that carry groups of genes coding for related proteins. An operon consists of an promoter, operator and coding sequences for structural proteins (regulatory and structural genes).

The promoter is the region in operon where RNA polymerase binds and initiates the process of transcription.

Regulatory DNA sequences are binding sites for regulatory proteins that control the expression of the operon "up" or "down." and structural genes code for proteins needed for cell function such as lactose metabolism.

Regulatory proteins acts as a repressor and when bind to operator, blocks the forward movement of RNA polymerase  on the DNA.

Hence, the correct option is b.
