Does plant cell have Mesosome?
No, mesosomes are structures found in prokaryotic cells, not in plant cells. Mesosomes are used for cellular respiration and are involved in cell division in prokaryotic organisms. Plant cells do not have mesosomes because they are eukaryotic and have a different structure and organization.
What percentage of earth's water is in the oceans?
The oceans contain 96.5% of all water.
The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles).
This represents 0.22 % of the total mass of the Earth.
More:
About 97.5% of water on Earth is salt water and 2.5% fresh water.

What factors affect the density of ocean water?
The two factors of primary importance affecting water density are temperature and salinity. These are an important influence on global ocean currents. The process of convergence and divergence also plays an important role on controlling the water density of Oceans.
In addition, the density of water increases slightly with increasing pressure and this can become a factor at the tremendous pressure of the deep ocean.
What is the most abundant substance dissolved in sea water?
The most abundant substance dissolved in sea water is sodium chloride, which is more commonly known as table salt. It makes up about 85% of the total dissolved solids in the ocean.
What are some effects convection currents have on the world?
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
What is the relationship between depth and sunlight?
The relationship between depth and sunlight is that sunlight penetration decreases as depth increases in water. This is due to the absorption and scattering of light by water molecules and particles. Consequently, less sunlight reaches deeper parts of the water column, affecting the availability of light for photosynthesis and primary production.
What is happening to the size of the south Atlantic ocean?
The South Atlantic Ocean is currently expanding due to the movement of tectonic plates. This process, known as seafloor spreading, occurs along the Mid-Atlantic Ridge where new crust is formed and pushes the existing crust apart, leading to the ocean's enlargement over time.
What is the temperature of the Twilight Zone?
The temperature of the Twilight Zone varies depending on the specific location within the ocean. On average, it ranges from around 40 to 60°F (4 to 15°C).
Marine Protected Areas in the China?
China has a number of marine protected areas all over the country. Some of these include the Liyashan National Marine Park in Jiangsu, the Xiamen National Marine Park in Fujian, and the Hailingdao National Marine Park in Guangdong.
Why are some oceans blue and others grey?
The ocean, or the water in the ocean, is actually colorless. They reflect the color of the sky above them so a blue ocean means the sky is mostly blue while a grey ocean means that the sky is grey or cloudy.
Banded sea kraits are a species of sea snake found in the Indo-Pacific region. They have distinctive black and white bands around their bodies and are highly venomous. These snakes are able to move on land and are known for their striking appearance and unique hunting behavior.
Does San Francisco have mountains?
San Francisco does not have mountains within the city limits. However, the city is surrounded by hilly terrain, with prominent peaks such as Twin Peaks and Mount Davidson providing scenic views of the area.
How deep is the intertisal zone?
The intertisal zone is not identified, however the intertidal zone is. The intertidal zone is that which is covered by water at high tide, and uncovered at low tide. The size and depth of this zone varies depending on geography.
What affects the heights of tides?
The heights of tides are primarily influenced by the gravitational pull of the moon and the sun on Earth's oceans. Other factors, such as the shape of coastlines, water depth, and the Earth's rotation, also play a role in determining the height of tides at specific locations.
What is an example of Floodplain?
An example of a floodplain is the area surrounding a river or stream that becomes flooded during periods of heavy rain or snowmelt. These flat, low-lying areas help to absorb excess water and reduce the risk of flooding in nearby communities. Farmers often utilize floodplains for agriculture due to the fertile soil deposited during flooding.
Where you can get info and a picture about Jewfish?
You can find information and pictures of Jewfish (also known as Goliath Grouper) on marine life websites, fish identification guides, or by searching for images on search engines like Google. Make sure to use reputable sources for accurate and reliable information.
What are two examples of sound communication tools?
Two examples of sound communication tools are telephones, which allow for real-time verbal communication over long distances, and public address systems, which are used to broadcast messages to a large audience in public spaces.
What plants live in temperate oceans?
Algae is (are) the most prevalent plant in the ocean. Indeed, the ONLY plant in the ocean. Seaweed, kelp, etc. are all different forms of algae. There are no rooted plants like we see on land, though some terrestrial plants, like mangroves, can live with their roots in salt water. Some macroalgae (like kelp) have "holdfasts" that attach them to rocks on the sea bed, but they are not true, nutrient-absorbing roots like terrestrial plants.
How much of earths water is drinkable?
71% of the world is covered with water, but the oceans are so deep, 97% of the water on Earth is salt water.
Of the remaining 3%, about 2% is in glaciers or otherwise unattainable.
About 1% of Earth's water is drinkable quality found mostly in fresh ground water.
What is the underwater edge of a continent called?
You can't have a continent rise from land, but you can have land rise from the continental shelf, which may be under water, and that is called an island.
Coral reef decay refers to the degradation and decline of coral reefs due to various factors such as pollution, overfishing, coral bleaching, and ocean acidification. This can lead to a loss of biodiversity, disruption of ecosystem services, and negative impacts on communities that rely on coral reefs for food and income. Conservation efforts are essential to protect and restore coral reefs.
What percent of the ocean consists of dissolved salts?
Approximately 3.5% of the ocean consists of dissolved salts, mostly sodium and chloride ions. This gives the ocean its characteristic salinity.
The ocean is often seen as a symbol of vastness, mystery, and depth. It can represent emotions, the unconscious mind, and the unknown aspects of life. Additionally, the ocean is associated with adaptability, fluidity, and the cycle of life.
Words that can be made out of "gnetsra" include "gants," "stern," "gears," and "anger."
No, a glacier is not living. It is a mass of ice formed by snow accumulation over a long period of time. Glaciers move slowly due to the force of gravity and changes in temperature, but they do not exhibit characteristics of living organisms like growth, reproduction, or metabolism.
