Answer:
Plants may compete with other organisms like phytoplankton for sunlight, their source of light energy for photosynthetic reactions.
Explanation:
Abiotic factors or non-living factors in terrestrial ecosystems include temperature, rainfail, and light; in other aquatic ecosystems, they also include salinity, and water currents.
Plant populations belong to the biotic factors within an environment, and often complete with other organisms such as fungi, animals and bacteria.
For instance, plants share their photosynthetic ability with some bacteria. In aquatic biomes, both phytoplankton, and aquatic plants compete for available sunlight underwater in order to make energy via photosynthesis.
Zygomycotes
Zygomycotes (conjugated fungi) produce non-septate hyphae with many nuclei
Its B.cell wall
ribosomes are used to synthesis proteins and other components required for cells
endoplamsic reticulum is where the ribosomes are its a structure that helps to prepare the components and to bring them to the golgi body
the cell wall is only present in plants (cellulose) and fungi (chitin) and it helps plants to regulate their water intake physically
the cytoplasmis present in all cells as the medium which organelles are suspended in and in contact with

A seedling is a young plant sporophyte creating out of a plant incipient organism from a seed. Seedling improvement begins with germination of the seed. A common youthful seedling comprises of three fundamental parts: the radicle, the hypocotyl, and the cotyledons.
Answer:
D. Psychrophile
Explanation:
Psychrophiles or cryophiles are a type of extremophiles i.e. they live in extreme environment. They grow well in low temperatures ranging from -20 to +10 degree Celsius.
Here, the bacteria was incubated at different temperatures. It did not show growth at standard incubation temperature of 37°C which indicates that it might be an extremophile preferring either very hot or very cold environment. But it also did not show growth at 50°C which means that it does not survive well at high temperature.
Lab bench top has generally colder surface compared to the surrounding environment and a little growth was observed there which indicates that this bacteria might require cold temperature for growth. The result was finally confirmed with abundant growth observed inside refrigerator which is only possible if it is a psychrophile.
