1) Different types of parenchyma ? And their location and Function ? please please mark me brainlist
Answer:
n the different regions of the plant body parenchyma cells are involved in different functions. On this basis, following types of parenchyma can be recognised.
Chlorenchyma is the parenchyma in which the cells contain large number of chloroplasts. Chlorenchyma takes part in photosynthesis. It occurs in the leaves and other green parts of the plant body.
Prosenchyma is a type of parenchyma where cells are elongated with tapering ends.
Arenchyma is the parenchyma in which the cells enclose large intercellular spaces that are filled with air. Aerenchyma helps in buoyancy and respiration. It is characteristically found in aquatic floating plants.
Vascular parenchyma is the parenchyma, which is found associated with the vascular tissues xylem and phloem. Accordingly, it is distinguished into xylem parenchyma and phloem parenchyma.
Medullary parenchyma is the parenchyma, which is found radially arranged in between the vascular bundles in the stem. It is meant for storage of reserve food.
Conjunctive parenchyma is the parenchyma, which occurs in the root system. It is specially meant for storage of water.
Armed parenchyma is the parenchyma, which is found in the epidermis of leaves in some gymnosperms. The cells have many spiny projections. It is defensive in function.
The term describes cells in both plant and animal tissues. In plants, parenchyma cells are a distinct type of tissue that can grow and divide and they have a thin cell wall. They make up flowers, leaves, and the inner parts of roots and stems that grow and divide. These cells secrete sap, exchange gases, and conduct photo synthesis. Plant parenchyma is classified into 4 shapes: polyhedral, stellate, elongated, and lobed.
In animals, parenchymal cells are the functional cells within the organism. This does not include those that have structural and/or protective functions like bone cells that make up a skeleton. In the brain, the parenchyma consists of neurons and glial cells. In addition, the cancer cells in tumors that are not involved with blood vessels are called parenchyma.
Answer:
a. Photosynthetic parenchyma: it is commonly found under the epidermis, where light is more intense. It is specialized in photosynthesis thanks to the many chloroplasts present in the cells.
b. Storage parenchyma: They are mostly found in solution, such as lipids, proteins, and others. Their function is to synthesize and store a number of substances.
c. Aquiferous parenchyma: It is present in plants that live in dry environments, known as xerophyte plants. Their function is to store some amount of water.

The images show fossils of a modern bird and two extinct organisms( a Tyrannosaurus rex and archaeopteryx). Based on the structure of the three organisms, it can be concluded that blank . The archaeopteryx and have wings, while dinosaurs have limbs. So, it can be concluded that blank.
Answer:
Many individuals consider that Archaeopteryx would have been the first bird, however, many paleontologists are against it. The findings of many fossils of Archaeopteryx have revealed that though the creature exhibited wings, the majority of its characteristics were of reptile, like the existence of full teeth set. Apart from this, the wings formation of the creature demonstrated that it was not completely capable of flying.
No matter what, the presence of wings makes them closely associated with the modern time birds. Thus, it can be concluded that Archaeopteryx could be considered as an intermediate between the reptiles and the birds and is a precursor to the modern-day birds' evolution.

Which of the following is an example of adaptive radiation? One population of squirrels becomes two separate species over a long time. One population of lizards forms 15 separate species over a short time. One species of birds becomes better suited to its environment over time. One species of fish forms when two species of fish begin to breed with each other.
Answer:
B. One population of lizards leads to 15 separate species over a short time.
Explanation:
Adaptive radiation is a process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges and opens environmental niches.
Adaptive radiation occurs when a single ancestral species diversifies into a variety of different species, each with different adaptations to fit different ecological niches.
When does the adaptive radiation occur ?This often occurs when a group of organisms colonizes a new, relatively unexploited environment, and the different ecological niches available in that environment drive the evolution of different adaptations in different subgroups.
The example of one population of lizards forming 15 separate species over a short time is a classic example of adaptive radiation. In this case, the ancestral population of lizards likely colonized a new area with many different ecological niches.
Over time, different subgroups of lizards evolved adaptations that allowed them to exploit these niches in different ways, leading to the diversification of the group into many different species.
