Which of the following organelles provide structure and rigidity to a plant cell?
ribosome
A cell membrane
B chloroplast
C cell wall
Answer:
cell wall
Explanation:
cell wall provide support for plant
The cell wall provides rigidity to a plant cell.
Cell wall :Cell wall is the outer layer surrounding the cell membrane. Cell wall is flexible, but it provides strength to cells. The main component of the plant cell wall is cellulose. Cell wall provides shape to the cell. It also protects the cell against some physical and mechanical damage.
Cell wall maintains turgor pressure in the cell. Cell wall is also present in fungi but it is absent in animals. ribosome helps in protein synthesis. It manufactures proteins for the cell. Cell membrane is also called plasma membrane. It helps in entry and exit of molecules.
Chloroplast is the chlorophyll containing cells. It is present in leaves of the plant cells. It helps in the process of photosynthesis.
Therefore, The cell wall provides rigidity to a plant cell.

Ο Ο Ο Ο
O a eukaryotic cell, because it contains a nucleus
O a prokaryotic cell, because it has compartmentalized organelles
Answer:
mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP). Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 μm. In addition to producing energy, mitochondria store calcium for cell signaling activities, generate heat, and mediate cell growth and death.

A) The process of wearing down, becoming weaker
Degradation
B) Animals eating vegetation at a rate faster than it can grow back
Exploitation
C) Saving of a resource by managing how it is used
Overgrazing
D) Unfair and unequal treatment of people or use of resources
The process of wearing down a substance leads to degradation, and the process of eating vegetation by the animal at a faster rate is called overgrazing. Thus, the correct options are A. 2, B. 4, C. 1, and D. 3.
What is degradation?Degradation is the process of wearing down the substance by the action of air, water, etc. which leads to erosion and weakening resulting in the formation of smaller particles. Hence, A. 2 is correct.
When the animals eat vegetation at a higher rate than their production causes the loss of food and decreases the carrying capacity in the process called overgrazing. Hence, B. 4 is correct.
Conservation is the process of saving resources by their effective uses, and exploitation is the unequal and unfair treatment and use of the resources and organisms. Hence, C. 1, and D. 3 are correct.
