Plants cells use photosynthesis from the sun, which requires them to have chloroplast filled with chlorophyll to complete this function; animal cells do not have chloroplasts. Chlorophyll also helps make plants green. Animal cells take on a round shape while plant cells form rectangular shapes.

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.

Commonalities of energy processing in both plants and animals have become even stronger by the finding that chloroplast can be found in animal cells.

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids.

One of the fun things to observe using a light microscope is the movement of chloroplasts around the cell, especially in the plant Elodea. This movement is referred to as cyclosis or cytoplasmic streaming.

plasmodesmata between mesophyll cells are aggregated in numerous thickened portions of the walls. The plasmodesmata are unbranched and all are characterized by the presence of electron-dense structures, called sphincters by us, near both ends of the plasmodesmatal canal.

The liver is one of the organs richest in mitochondria. Hepatic mitochondria have unique features compared to other organs’ mitochondria, since they are the hub that integrates hepatic metabolism of carbohydrates, lipids, and proteins.

Answer: liver and muscle cell have more mitochondria than other types of cells — as Muscles take part in various physical activities requiring more energy. these two types of cells need more power and energy in comparison to all other types of cells in our body.

A. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!

Some different cells have different amounts of mitochondria because they need more energy. So for example, the muscle has a lot of mitochondria, the liver does too, the kidney as well, and to a certain extent, the brain, which lives off of the energy those mitochondria produce.

Eukaryotic Exceptions Some parasitic protists, for example, take energy from their hosts and do not have mitochondria, as explained by an article in the Journal of Eukaryotic Microbiology. In humans, mature red blood cells, or erythrocytes, lack mitochondria as well, as reported by the Encyclopedia Britannica.

During fertilization, only the sperm’s head containing its DNA will penetrate the egg and the two nuclei fuse. The sperm’s midpiece contains many mitochondria so that a supply of energy is available for the sperm to perform its function of traveling to and later fertilizing the egg.

And each one has many mitochondria (where respiration occurs) to release the energy needed for its journey. Sperm cells also have special enzymes, called acrosomes, which allow them to break through the cell membrane of the egg. Sperms are more active than eggs so they have more mitochondria.

A sperm is usually a small, compact cell, highly specialized for the task of fertilizing an egg. Sperm differentiation is therefore directed by the products from both parental chromosomes, even though each nucleus is haploid.

Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells.
