Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.

During plant growth, energy is provided as sugars and ATP by two key organelles of the plant cells, chloroplasts and mitochondria. Both organelles contain double membranes including characteristic internal membranes, called thylakoids in chloroplasts and cristae in mitochondria.

The correct answer is option A. Ribosomes are protein-nucleic acid complexes that function in the translation phase of protein synthesis. Ribosomes in eukaryotic cells could either be found in the cytoplasm or in the rough endoplasmic reticulum. During translation, the messenger RNA attaches to the ribosome.

Two types of membranous organelles that specialize in energy conversion are the chloroplasts and mitochondria. Chloroplasts use solar energy to make carbohydrates by using photosynthesis.

Mitochondria are organelles that are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule.

Passive transport requires no energy from the cell. Examples include the diffusion of oxygen and carbon dioxide, osmosis of water, and facilitated diffusion.

Three transport processes that do not require energy are; diffusion, osmosis and facilitated diffusion.

Active transport

The four major types of passive transport are (1) simple diffusion, (2) facilitated diffusion, (3) filtration, and (4) osmosis.

The different modes of transport are air, water, and land transport, which includes Rails or railways, road and off-road transport. Other modes also exist, including pipelines, cable transport, and space transport.

Railways

Five Major Modes of Transportation

• Road transport.
• Railway transport.
• Water transport.
• Air transport.
• Pipeline transport.

Water transportation

Air transportation

Car is the most comfortable means of transportation.

Air transport

The air travel, today, is the fastest, most comfortable and prestigious mode of transport. It has reduced distances by minimising the travel time.

Water: The Oldest Means of Transportation.

In comparison to the land and air transport, water transport is the slowest form of movement of commodities.

Some power induced in three wheel transports is two slow power . Explanation: Using as a means of transport by human and it is for good purpose used. Existence of transport as it is the time form that is used for walking, running etc.

• Means of travel help us to move people from one place to another.
• Aeroplane is the fastest means of transport.
• Communication means talking or writing to someone.
• Telephone is the slowest means of communication.

*Air Air transport is faster because it has less resistance and friction, whereas water transport is slower because the waves will crash against whatever you are using for transport and slow it down. Water transport is the process of moving people, goods, etc.

Traveling by plane is the fastest means of transport known to humankind making it the choice method of travel when you need to get to your destination much faster. Road transport is hectic, some journeys which will only take an hour by air will take you over seven hours if you choose to use road transport.

in road transport we travel from one to another by bus, car or any other vehicle that can travel on road. in rail transport we travel by trains from one place to another on rails.

The movement of passengers and cargo by aircraft such as airplanes and helicopters. Air transportation has become the primary means of common-carrier traveling. Air transportation also provides a communication or medical link, which is sometimes vital, between the different groups of people being served.

Types of air transport

• Aeroplanes.
• Helicopters.
• Hot air balloons.
• Blimps.
• Gliders.

What Happens If You Forget to Turn On Airplane Mode? Not only will the signals cause interference with airplane navigation, but the effort it takes your cell phone to keep scanning and tower hopping at fly-by speeds will also drain your battery and still not maintain a constant signal.

Two modes of air transport are helicopters and aeroplanes. Helicopters fly at a low altitude and are most frequently used for travelling short distances due to its low speed. Aeroplanes travel at a high altitude and they have a greater speed, travel long distances and can accommodate more individuals for traveling.
