How do our bodies have so many different types of cells with different functions?
Rainbow [258]

Answer:

Humans are multicellular, complex organisms. The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.

For example:

Cells in the brain may be longer in shape so they can transmit signals more efficiently.

Cells of the heart have more mitochondria because they need a lot of energy.

Cells in the respiratory system are responsible for taking up oxygen and releasing carbon dioxide.

All the cells work together to keep the human body running efficiently.

Why is it difficult for persons to survive on planet mercury?
aliya0001 [1]
Mercury is a barren planet with little atmosphere. In many regards it is similar to our own moon. However, it is also very close to the Sun, so humans will have to set up bases in craters or near the Poles to avoid being blinded.

What types of eukaryotic cells have vacuoles that act like lysosomes ?
irga5000 [103]
Plant cells

<span>There are several starting ingredients that are required for starting the process of photosynthesis. The most important are sunlight, water, carbon dioxide and certain minerals. Sunlight helps in building up the optimum temperature that is required to start the process of photosynthesis. Water is an important raw material that helps to absorb the carbon dioxide from the air. It also directly influences the opening and closing of the stomata. Carbon dioxide on the other hand is one of the most important raw material that helps to make glucose via the process of photosynthesis.</span>
