Explanation:
The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize. Maize dry seeds are exposed to a gamma source at doses ranging from 0.1 to 1 kGy. Our results show that the germination potential, expressed through the final germination percentage and the germination index, as well as the physiological parameters of maize seedlings (root and shoot lengths) decreased by increasing the irradiation dose. Moreover, plants derived from seeds exposed at higher doses did not survive more than 10 days. Biochemical differences based on photosynthetic pigment (chlorophyll a, chlorophyll b, carotenoids) content revealed an inversely proportional relationship to doses of exposure. Furthermore, the concentration of chlorophyll a was higher than chlorophyll b in both irradiated and non-irradiated seedlings. Electron spin resonance spectroscopy used to evaluate the amount of free radicals induced by gamma ray treatment demonstrates that the relative concentration of radiation-induced free radicals depends linearly on the absorbed
All the different plant populations make up the plant community in this swamp. The plants are part of a bigger ecosystem that contains many abiotic and biotic factors.
<h3>What is an Ecosystem?</h3>
An ecosystem may be defined as a place or an area that involves individuals of different species that live together and interact with one another for the purpose of food, shelter, and space.
In ecology, a community may be defined as a group of individuals belonging to different species that are living in the same area at a given time.
So, all the different plant populations make up a plant community.
Therefore, the community is the collection of all different forms of species but the ecosystem is the community has highly influenced by abiotic and biotic factors.

Reptiles, like early dinosaurs.

Hey There!</h2><h2>

Answer:</h2>
Chloroplasts are found in Eukaryotic Autotrophs i.e. those who can make their own food with the help of sunlight using carbon dioxide and water. Eukaryotes are Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
<h2>_____________________________________</h2><h3>Example:</h3>
The Example of Eukaryotic Autotrophs are Plants and Algae. They are the producers in the food chain also the main source of the oxygen, as they use Carbon Dioxide for a glucose's carbon structure and releases oxygen as By-Product.
<h2>_____________________________________</h2><h3>Why are they green?</h3>
Chloroplasts get their green color by the presence of chlorophyll, which is the main site for the process of photosynthesis. It is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and all the other colors to the lesser extent while reflecting green. They are present in leaves, and as the chlorophyll reflect green color, Thus the leaves look green to us.
